harry123 · ‎2024-07-20

I am using my own custom board which is replicate of stm32f429 disc1 development board.
I replaced main mcu chip i.e stm32f429 and stlink chip from my disc1 board to my custom board. After using my custom board for for many days now it stopped working.
The board is getting heated and st-link not detected error is getting popped one i connect usb power supply.
I unable to find the reason for its failure.I have attached my custom board schematic.
Now I want make another custom board with external debugger what changes I have to make in the schematic to make my board work like disc1 board.
