Should code that runs on F303re Nucleo run on F303ze nucleo? Virtual Comm port issues

DPeki.1 · ‎2022-11-02

Hello. I have a project that runs fine on F303RE Nucleo board. I loaded it on the F303ZE Nucleo board and I get no banner displayed on the Virtual Comm port. The device manager sees the port fine.

Are there any solder bridges or jumpers needed on the ZE board to enable the VCP?

Thanks,

Dave

You should also note that both NUCLEO use different target packages:

NUCLEO-F302R8 = NUCLEO-64, VCP via USART2, SB13, SB14
NUCLEO-F303ZE = NUCLEO-144, VCP via USART3, SB5, SB6

Hello @DPeki.1,

Try to connect using STM32Cubeprogrammer.

You can check the solder bridges and jumpers needed on the nucleo-F303ZE board in the UM1974.

Thank you for your contribution.

Thank you. That explains it. I was naive to think it was just pin configurations differences between the two boards F303RE and F303ZE.
