STM32H7 Ethernet works on restart and release mode but not on debug

Hi everyone,

I’m working with a custom board that uses the STM32H733VGT and the LAN8742AI Ethernet PHY. I’ve configured the MPU and middleware following the ST example for the STM32H75_DISCO board. The board responds to ping in release mode and after a watchdog reset in debug mode—but it fails to respond on the first run after flashing or power-up.

Please find attached my .ioc and ETH Init function file in the attachments.

 

Any comment or advice would be highly appreciated.

Tnx,

Amir
