Failed to connect STM32G431C8U6 via UART (Error: GETID command not acknowledged!)

Hello,

I'm trying to burn my program into the STM32G431C8U6 chip with UART on my PIN9 and PIN10.

When I want to connect the chip with STMCubeProgrammer and I got the following output:

I'm using a optoisolator then an USB toTTL converter to connect the PC and the board. I have checked several times the chip power supply the state of boot0 and the uart wiring. Do you have any ideas as to where the problem is?

Thanks

Hello @Chanles and welcome to the Community :)

Which CubeProgrammer version are you using?

Are you making a reset in your application? Are you selecting "Run after programming"?

Could you please share the Option Bytes states?

Check this post, this may help you!

Hi Sir,

I'm using the version 2.15.0

Yes, I have the reset on my board and I tried but had the same result.

I dont select "Run after programming" cause it's a new chip and there's no program in it and I haven't been able to successfully connect and read the Option Bytes
