Subject: [Zephyr-users] STM32: Ethernet Driver not working on F7 and H7 with 2.4.0 #driver #ethernet #stm32 #networking

 

Dear all,

We try to run the net/sockets/packet sample on both, the Nucleo F746ZG and the H747I Discovery Board an run into the following issue with version 2.4.0 (works fine with 2.3.0 on F7):

Has anyone encountered this behavior with the Ethernet driver on the STM32? It seems like the ethernet driver (eth_stm_32_hal.c) is not able to pass on the received packets to the buffer using net_pkt_rx_alloc_with_buffer().

Regards,

Andreas
