config RP2040_FLASH_BOOT
bool "flash boot"
default y
---help---
If y, the built binary can be used for flash boot.
If not, the binary is for SRAM boot.
config RP2040_FLASH_CHIP
string "flash chip name"
default "w25q080"
---help---
Name of NOR flash device connected to RP2040 SoC.
(Used to choose the secondary boot loader.)
Basically this option should not be changed.
config RP2040_UF2_BINARY
bool "uf2 binary format"
default y
---help---
Create nuttx.uf2 binary format used on RP2040 based arch.
