Hello Everyone, I hope this message finds you well. I am currently working with a custom board based on the **STM32G474RE** microcontroller and attempting to program it using **PLECS Coder**. Unfortunately, I’m encountering an issue during the build and flashing process. Even a simple LED blinking test fails. To clarify: - The custom board **functions correctly** when tested with **STM32CubeIDE**. - The **PLECS simulation** is also working properly, as the same test (blinking an LED) runs fine on a standard STM32G474RE board. - The issue arises when I try to connect and program my **custom board** via **PLECS** I get this error : Error in build step #6 (Make): Make process exited with code 2: “C:/Users/Sajjad/Desktop/Coder\_Targert/tsp\_stm32/bin/c2p-gdb/c2p-gdb” load --server-cmd “"C:/Users/Sajjad/Desktop/Coder\_Targert/tsp\_stm32/bin/openocd/bin/openocd" -s "C:/Users/Sajjad/Desktop/Coder\_Targert/tsp\_stm32/bin/openocd/share/openocd/scripts" -f board/stm32g431.cfg” --server-start-delay 1000 --port 3333 --nvic 0x8000000 ./output\_STM32G474RE/G474RE.elf Architecture: arm Unable to load binary “./output\_STM32G474RE/G474RE.elf”.

Are you sure that you executed to **entire** command that I provided, including the `-c` arguments? I would have expected to see information about the flash and its protection settings. ---

> [@Beat\_Arnet](#): > > Are you sure that you executed to **entire** command that I provided, including the `-c` arguments? I would have expected to see information about the flash and its protection settings. Yesterday, the first time I ran the following command: “C:/Users/Sajjad/Desktop/Coder\_Targert/tsp\_stm32/bin/openocd/bin/openocd” -s “C:/Users/Sajjad/Desktop/Coder\_Targert/tsp\_stm32/bin/openocd/share/openocd/scripts” -f board/stm32g431.cfg -c “init” -c “reset halt” -c “flash probe 0” -c “flash info 0” -c “shutdown” as you suggested. I got the output shown in the first screenshot of the CMD window. i am sure that i did not anything, but after running the command again, I received the output in the second screenshot — and the board was successfully programmed. I was even able to use external mode via JTAG. However, today I’m working with the board again and facing the same issue as before. No matter what I try, nothing seems to solve the problem. ---

the problem was solder jumper of NRST on my board its soldering was weak. ---

Nice debugging! I am glad you figured it out.
