STM32: Ethernet Driver not working on F7 and H7 with 2.4.0 #stm32 #driver #ethernet #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().

Dejavu, I think I have seen this question before. I don’t have a H7 or F7, but I remember a similar question was posted in April. Here is what it said, unfortunately there was no follow up to say if this helped or not.:

 

Hi Erik,

 

you are running out of RX network buffers. Try to increase the value of CONFIG_NET_BUF_RX_COUNT and optionally CONFIG_NET_PKT_RX_COUNT options.

 

Cheers,

Jukka

Andreas,

 

Can you bisect this to narrow down where things stopped working for you?
