Hi everybody,
I found a bug in STMCubeMX in the way it generates .ld scripts.
Context:
- STMCubeMX V 6.12.1 (linux)
- EVK : NUCLEO-F446RE
- Toolchain/IDE : Makefile
- arm-none-eabi-gcc (GNU Arm Embedded Toolchain 10.3-2021.10) 10.3.1 20210824 (release)
Problem:
The STM32F446RE Tx_FLUSH.ld file generated by STMCubeMX contains several errors that do not allow a link to be made correctly using Makefile.
Here are the difference :
Notice:
- the STM32F446RETx_FLASH.ld.CubeMx is the one generated by STMCubeMX
- the STM32F446RETx_FLASH.ld is the corrected one
They are both stored in the attached zip.
