+/* The PX4 FMUV6X uses an STM32H753II has 2048Kb of main FLASH memory.
+ * The flash memory is partitioned into a User Flash memory and a System
+ * Flash memory. Each of these memories has two banks:
+ *
+ *   1) User Flash memory:
+ *
+ *      Bank 1: Start address 0x0800:0000 to 0x080F:FFFF with 8 sectors, 128Kb each
+ *      Bank 2: Start address 0x0810:0000 to 0x081F:FFFF with 8 sectors, 128Kb each
+ *
+ *   2) System Flash memory:
+ *
+ *      Bank 1: Start address 0x1FF0:0000 to 0x1FF1:FFFF with 1 x 128Kb sector
+ *      Bank 1: Start address 0x1FF4:0000 to 0x1FF5:FFFF with 1 x 128Kb sector
+ *
+ *   3) User option bytes for user configuration, only in Bank 1.
+ *
+ * In the STM32H743II, two different boot spaces can be selected through
+ * the BOOT pin and the boot base address programmed in the BOOT_ADD0 and
+ * BOOT_ADD1 option bytes:
+ *
+ *   1) BOOT=0: Boot address defined by user option byte BOOT_ADD0[15:0].
+ *      ST programmed value: Flash memory at 0x0800:0000
+ *   2) BOOT=1: Boot address defined by user option byte BOOT_ADD1[15:0].
+ *      ST programmed value: System bootloader at 0x1FF0:0000
+ *
+ * The PX4 FMUV6X has a test point on board, the BOOT0 pin is at ground so by
+ * default, the STM32 will boot to address 0x0800:0000 in FLASH unless the test
+ * point is pulled to 3.3V.then the boot will be from 0x1FF0:0000
+ *
+ * The STM32H743II also has 1024Kb of data SRAM.
+ * SRAM is split up into several blocks and into three power domains:
+ *
+ *   1) TCM SRAMs are dedicated to the Cortex-M7 and are accessible with
+ *      0 wait states by the Cortex-M7 and by MDMA through AHBS slave bus
+ *
+ *      1.1) 128Kb of DTCM-RAM beginning at address 0x2000:0000
+ *
+ *           The DTCM-RAM is organized as 2 x 64Kb DTCM-RAMs on 2 x 32 bit
+ *           DTCM ports. The DTCM-RAM could be used for critical real-time
+ *           data, such as interrupt service routines or stack / heap memory.
+ *           Both DTCM-RAMs can be used in parallel (for load/store operations)
+ *           thanks to the Cortex-M7 dual issue capability.
+ *
+ *      1.2)  64Kb of ITCM-RAM beginning at address 0x0000:0000
+ *
+ *           This RAM is connected to ITCM 64-bit interface designed for
+ *           execution of critical real-times routines by the CPU.
+ *
+ *   2) AXI SRAM (D1 domain) accessible by all system masters except BDMA
+ *      through D1 domain AXI bus matrix
+ *
+ *      2.1) 512Kb of SRAM beginning at address 0x2400:0000
+ *
+ *   3) AHB SRAM (D2 domain) accessible by all system masters except BDMA
+ *      through D2 domain AHB bus matrix
+ *
+ *      3.1) 128Kb of SRAM1 beginning at address 0x3000:0000
+ *      3.2) 128Kb of SRAM2 beginning at address 0x3002:0000
+ *      3.3)  32Kb of SRAM3 beginning at address 0x3004:0000
+ *
+ *      SRAM1 - SRAM3 are one contiguous block: 288Kb at address 0x3000:0000
+ *
+ *   4) AHB SRAM (D3 domain) accessible by most of system masters
+ *      through D3 domain AHB bus matrix
+ *
+ *      4.1)  64Kb of SRAM4 beginning at address 0x3800:0000
+ *      4.1)   4Kb of backup RAM beginning at address 0x3880:0000
+ *
+ * When booting from FLASH, FLASH memory is aliased to address 0x0000:0000
+ * where the code expects to begin execution by jumping to the entry point in
+ * the 0x0800:0000 address range.
+ *
+ * The bootloader uses the first sector of the flash, which is 128K in length.

+/* The PX4 FMUV6X uses an STM32H753II has 2048Kb of main FLASH memory.
+ * The flash memory is partitioned into a User Flash memory and a System
+ * Flash memory. Each of these memories has two banks:
+ *
+ *   1) User Flash memory:
+ *
+ *      Bank 1: Start address 0x0800:0000 to 0x080F:FFFF with 8 sectors, 128Kb each
+ *      Bank 2: Start address 0x0810:0000 to 0x081F:FFFF with 8 sectors, 128Kb each
+ *
+ *   2) System Flash memory:
+ *
+ *      Bank 1: Start address 0x1FF0:0000 to 0x1FF1:FFFF with 1 x 128Kb sector
+ *      Bank 1: Start address 0x1FF4:0000 to 0x1FF5:FFFF with 1 x 128Kb sector
+ *
+ *   3) User option bytes for user configuration, only in Bank 1.
+ *
+ * In the STM32H743II, two different boot spaces can be selected through
+ * the BOOT pin and the boot base address programmed in the BOOT_ADD0 and
+ * BOOT_ADD1 option bytes:
+ *
+ *   1) BOOT=0: Boot address defined by user option byte BOOT_ADD0[15:0].
+ *      ST programmed value: Flash memory at 0x0800:0000
+ *   2) BOOT=1: Boot address defined by user option byte BOOT_ADD1[15:0].
+ *      ST programmed value: System bootloader at 0x1FF0:0000
+ *
+ * The PX4 FMUV6X has a test point on board, the BOOT0 pin is at ground so by
+ * default, the STM32 will boot to address 0x0800:0000 in FLASH unless the test
+ * point is pulled to 3.3V.then the boot will be from 0x1FF0:0000
+ *
+ * The STM32H743II also has 1024Kb of data SRAM.
+ * SRAM is split up into several blocks and into three power domains:
+ *
+ *   1) TCM SRAMs are dedicated to the Cortex-M7 and are accessible with
+ *      0 wait states by the Cortex-M7 and by MDMA through AHBS slave bus
+ *
+ *      1.1) 128Kb of DTCM-RAM beginning at address 0x2000:0000
+ *
+ *           The DTCM-RAM is organized as 2 x 64Kb DTCM-RAMs on 2 x 32 bit
+ *           DTCM ports. The DTCM-RAM could be used for critical real-time
+ *           data, such as interrupt service routines or stack / heap memory.
+ *           Both DTCM-RAMs can be used in parallel (for load/store operations)
+ *           thanks to the Cortex-M7 dual issue capability.
+ *
+ *      1.2)  64Kb of ITCM-RAM beginning at address 0x0000:0000
+ *
+ *           This RAM is connected to ITCM 64-bit interface designed for
+ *           execution of critical real-times routines by the CPU.
+ *
+ *   2) AXI SRAM (D1 domain) accessible by all system masters except BDMA
+ *      through D1 domain AXI bus matrix
+ *
+ *      2.1) 512Kb of SRAM beginning at address 0x2400:0000
+ *
+ *   3) AHB SRAM (D2 domain) accessible by all system masters except BDMA
+ *      through D2 domain AHB bus matrix
+ *
+ *      3.1) 128Kb of SRAM1 beginning at address 0x3000:0000
+ *      3.2) 128Kb of SRAM2 beginning at address 0x3002:0000
+ *      3.3)  32Kb of SRAM3 beginning at address 0x3004:0000
+ *
+ *      SRAM1 - SRAM3 are one contiguous block: 288Kb at address 0x3000:0000
+ *
+ *   4) AHB SRAM (D3 domain) accessible by most of system masters
+ *      through D3 domain AHB bus matrix
+ *
+ *      4.1)  64Kb of SRAM4 beginning at address 0x3800:0000
+ *      4.1)   4Kb of backup RAM beginning at address 0x3880:0000
+ *
+ * When booting from FLASH, FLASH memory is aliased to address 0x0000:0000
+ * where the code expects to begin execution by jumping to the entry point in
+ * the 0x0800:0000 address range.

+/* The PX4 FMUV6X uses an STM32H753II has 2048Kb of main FLASH memory.
+ * The flash memory is partitioned into a User Flash memory and a System
+ * Flash memory. Each of these memories has two banks:
+ *
+ *   1) User Flash memory:
+ *
+ *      Bank 1: Start address 0x0800:0000 to 0x080F:FFFF with 8 sectors, 128Kb each
+ *      Bank 2: Start address 0x0810:0000 to 0x081F:FFFF with 8 sectors, 128Kb each
+ *
+ *   2) System Flash memory:
+ *
+ *      Bank 1: Start address 0x1FF0:0000 to 0x1FF1:FFFF with 1 x 128Kb sector
+ *      Bank 1: Start address 0x1FF4:0000 to 0x1FF5:FFFF with 1 x 128Kb sector
+ *
+ *   3) User option bytes for user configuration, only in Bank 1.
+ *
+ * In the STM32H743II, two different boot spaces can be selected through
+ * the BOOT pin and the boot base address programmed in the BOOT_ADD0 and
+ * BOOT_ADD1 option bytes:
+ *
+ *   1) BOOT=0: Boot address defined by user option byte BOOT_ADD0[15:0].
+ *      ST programmed value: Flash memory at 0x0800:0000
+ *   2) BOOT=1: Boot address defined by user option byte BOOT_ADD1[15:0].
+ *      ST programmed value: System bootloader at 0x1FF0:0000
+ *
+ * The PX4 FMUV6X has a test point on board, the BOOT0 pin is at ground so by
+ * default, the STM32 will boot to address 0x0800:0000 in FLASH unless the test
+ * point is pulled to 3.3V.then the boot will be from 0x1FF0:0000
+ *
+ * The STM32H743II also has 1024Kb of data SRAM.
+ * SRAM is split up into several blocks and into three power domains:
+ *
+ *   1) TCM SRAMs are dedicated to the Cortex-M7 and are accessible with
+ *      0 wait states by the Cortex-M7 and by MDMA through AHBS slave bus
+ *
+ *      1.1) 128Kb of DTCM-RAM beginning at address 0x2000:0000
+ *
+ *           The DTCM-RAM is organized as 2 x 64Kb DTCM-RAMs on 2 x 32 bit
+ *           DTCM ports. The DTCM-RAM could be used for critical real-time
+ *           data, such as interrupt service routines or stack / heap memory.
+ *           Both DTCM-RAMs can be used in parallel (for load/store operations)
+ *           thanks to the Cortex-M7 dual issue capability.
+ *
+ *      1.2)  64Kb of ITCM-RAM beginning at address 0x0000:0000
+ *
+ *           This RAM is connected to ITCM 64-bit interface designed for
+ *           execution of critical real-times routines by the CPU.
+ *
+ *   2) AXI SRAM (D1 domain) accessible by all system masters except BDMA
+ *      through D1 domain AXI bus matrix
+ *
+ *      2.1) 512Kb of SRAM beginning at address 0x2400:0000
+ *
+ *   3) AHB SRAM (D2 domain) accessible by all system masters except BDMA
+ *      through D2 domain AHB bus matrix
+ *
+ *      3.1) 128Kb of SRAM1 beginning at address 0x3000:0000
+ *      3.2) 128Kb of SRAM2 beginning at address 0x3002:0000
+ *      3.3)  32Kb of SRAM3 beginning at address 0x3004:0000
+ *
+ *      SRAM1 - SRAM3 are one contiguous block: 288Kb at address 0x3000:0000
+ *
+ *   4) AHB SRAM (D3 domain) accessible by most of system masters
+ *      through D3 domain AHB bus matrix
+ *
+ *      4.1)  64Kb of SRAM4 beginning at address 0x3800:0000
+ *      4.1)   4Kb of backup RAM beginning at address 0x3880:0000
+ *
+ * When booting from FLASH, FLASH memory is aliased to address 0x0000:0000
+ * where the code expects to begin execution by jumping to the entry point in
+ * the 0x0800:0000 address range.
+ *
+ * The bootloader uses the first sector of the flash, which is 128K in length.

+ *   2) System Flash memory:
+ *
+ *      Bank 1: Start address 0x1FF0:0000 to 0x1FF1:FFFF with 1 x 128Kb sector
+ *      Bank 1: Start address 0x1FF4:0000 to 0x1FF5:FFFF with 1 x 128Kb sector
+ *
+ *   3) User option bytes for user configuration, only in Bank 1.
+ *
+ * In the STM32H743II, two different boot spaces can be selected through
+ * the BOOT pin and the boot base address programmed in the BOOT_ADD0 and
+ * BOOT_ADD1 option bytes:
+ *
+ *   1) BOOT=0: Boot address defined by user option byte BOOT_ADD0[15:0].
+ *      ST programmed value: Flash memory at 0x0800:0000
+ *   2) BOOT=1: Boot address defined by user option byte BOOT_ADD1[15:0].
+ *      ST programmed value: System bootloader at 0x1FF0:0000
+ *
+ * The PX4 FMUV6X has a test point on board, the BOOT0 pin is at ground so by
+ * default, the STM32 will boot to address 0x0800:0000 in FLASH unless the test
+ * point is pulled to 3.3V.then the boot will be from 0x1FF0:0000
+ *
+ * The STM32H743II also has 1024Kb of data SRAM.
+ * SRAM is split up into several blocks and into three power domains:
+ *
+ *   1) TCM SRAMs are dedicated to the Cortex-M7 and are accessible with
+ *      0 wait states by the Cortex-M7 and by MDMA through AHBS slave bus
+ *
+ *      1.1) 128Kb of DTCM-RAM beginning at address 0x2000:0000
+ *
+ *           The DTCM-RAM is organized as 2 x 64Kb DTCM-RAMs on 2 x 32 bit
+ *           DTCM ports. The DTCM-RAM could be used for critical real-time
+ *           data, such as interrupt service routines or stack / heap memory.
+ *           Both DTCM-RAMs can be used in parallel (for load/store operations)
+ *           thanks to the Cortex-M7 dual issue capability.
+ *
+ *      1.2)  64Kb of ITCM-RAM beginning at address 0x0000:0000
+ *
+ *           This RAM is connected to ITCM 64-bit interface designed for
+ *           execution of critical real-times routines by the CPU.
+ *
+ *   2) AXI SRAM (D1 domain) accessible by all system masters except BDMA
+ *      through D1 domain AXI bus matrix
+ *
+ *      2.1) 512Kb of SRAM beginning at address 0x2400:0000
+ *
+ *   3) AHB SRAM (D2 domain) accessible by all system masters except BDMA
+ *      through D2 domain AHB bus matrix
+ *
+ *      3.1) 128Kb of SRAM1 beginning at address 0x3000:0000
+ *      3.2) 128Kb of SRAM2 beginning at address 0x3002:0000
+ *      3.3)  32Kb of SRAM3 beginning at address 0x3004:0000
+ *
+ *      SRAM1 - SRAM3 are one contiguous block: 288Kb at address 0x3000:0000
+ *
+ *   4) AHB SRAM (D3 domain) accessible by most of system masters
+ *      through D3 domain AHB bus matrix
+ *
+ *      4.1)  64Kb of SRAM4 beginning at address 0x3800:0000
+ *      4.1)   4Kb of backup RAM beginning at address 0x3880:0000
+ *
+ * When booting from FLASH, FLASH memory is aliased to address 0x0000:0000
+ * where the code expects to begin execution by jumping to the entry point in
+ * the 0x0800:0000 address range.

Should investigate the coexist option again added ifdef to not use timer 0 when wifi enabled - reverted esp32 rt_timer to make use of timer 0 by default fix setting incorrect bit in hrt timer register - hrt running as expected, but on startup the pwm_out driver starts up at about 200Hz and then rises over a minute or so 250Hz. Not sure if this was present previously, and could be due to Wifi running at time priority on timer 0 pull xtensa compilers in setup.ubuntu.sh revert logger stacksize and cmake argument esp32 chip revision and PX4 UUID implemented spi board reset implemented, formatting checked devkit acts on startup as a wifi bridge for comms - the most usefull setting for the general developer when buying a esp32 devkit - testing Mavlink shell using ./Tools/mavlink_shell.py - todo: Test mavlink messages being forward improve wifi telemetry by increasing prio - Remove power save mode on wifi - increased daemon thread schedule priority to 50 compiles without Nuttx changes - updated compiler settings to match those of nuttx on px4 side add espressif_esp32 to excluded boards ci: allow docker to find xtensa compilers	2025-08-19 11:09:56 -07:00
