How to setup Eclipse for for cross compilation and cross debugging?

Hello,

Basically you need to establish in Eclipse the same environemnt as created by sourcing environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi

Following are the settings I use for Eclipse IDE for C/C++ Developers / Version: 2019-03 (4.11.0)

First you need choose during creation of a new project select "Cross gcc".

Then set in cross settings prefix and path

In compiler settings I use:

-O0 -g3 -Wall -c -fmessage-length=0 -march=armv7ve -mthumb -mfpu=neon-vfpv4 -mfloat-abi=hard -mcpu=cortex-a7 --sysroot=/home/osboxes/STM32MPU_workspace/STM32MP15-Ecosystem-v1.2.0/Developer-Package/SDK/sysroots/cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi

And linker settings:  -march=armv7ve -mthumb -mfpu=neon-vfpv4 -mfloat-abi=hard -mcpu=cortex-a7

--sysroot=/home/osboxes/STM32MPU_workspace/STM32MP15-Ecosystem-v1.2.0/Developer-Package/SDK/sysroots/cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed

Hope this helps
