From 58aff8491191634e4c913b82582bcd639a0b3533 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Beat=20K=C3=BCng?= Date: Thu, 9 Mar 2017 10:16:22 +0100 Subject: [PATCH] stm32f4discovery NuttX defconfig: lower CONFIG_DEV_PIPE_SIZE to 70 This saves almost 2kb of RAM when using the mavlink shell. 70 matches the size of the mavlink message. Since the pipe is blocking, a process writing a lot of data will just wait, data will not be dropped. The mavlink shell is the only process creating a pipe. --- nuttx-configs/px4-stm32f4discovery/nsh/defconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/nuttx-configs/px4-stm32f4discovery/nsh/defconfig b/nuttx-configs/px4-stm32f4discovery/nsh/defconfig index 063b604de8..4bfb7fac86 100644 --- a/nuttx-configs/px4-stm32f4discovery/nsh/defconfig +++ b/nuttx-configs/px4-stm32f4discovery/nsh/defconfig @@ -829,7 +829,7 @@ CONFIG_WATCHDOG_DEVPATH="/dev/watchdog0" # CONFIG_EEPROM is not set CONFIG_PIPES=y CONFIG_DEV_PIPE_MAXSIZE=1024 -CONFIG_DEV_PIPE_SIZE=1024 +CONFIG_DEV_PIPE_SIZE=70 CONFIG_DEV_FIFO_SIZE=0 # CONFIG_PM is not set # CONFIG_POWER is not set
