Use Chibistudio with STM32L475VCT6

Postby sprehse » Thu May 21, 2020 3:18 pm

Hello everyone
I have a question about flashing STM32 controllers

I have created a project on a Nucleo64-L476RG and now I want to flash the program on an STM32L475VCT6. Unfortunately I do not know exactly whether it is possible at all and if so at which points in the config I have to make adjustments.
In addition, I use an ST-Link v2 to flash the L475, now. Starting the openocd with the L4-nucleo.cfg was correct or not?
I tried to flash the code but I got this message in the console window.

symbol-file C:\\ChibiStudio\\workspace_user\\SW_Slave_V2\\build\\ch.elf

Are you using the latest ChibiStudio? it includes a tool to generate debug configurations automatically:


Using L4-nucleo config is correct.

Hey Giovanni,
thanks for the reply.
No i have used the previous Verison of ChibiOS.
So i have update now and use the debug generation tool. It works now.
Thank you :).
