Hello everyone,I'm using the STM32H7 and the new fully reworked ethernet driver along with the LWIP and FreeRTOS for sending and receiving the UDP packets. The issue is first two packets get corrupted when sending. I don't send the UDP packet with ze...

Hi, I've been using the STM32H7 example which uses the new reworked Ethernet driver (https://github.com/STMicroelectronics/STM32CubeH7). Changed the application layer of the example (LwIP_HTTP_Server_Netconn_RTOS) and during larger transfers, the DMA...

Hello everyone,I'm trying to set up the LwIP and FreeRTOS on the STM32H7.Currently I can send UDP packet from the client (STM32H7) to the server (PC),but I cannot ping the STM32H7.There is the main.c in the attachment and the lwipopts, ethernetif and...

Hi ktrofimo,I managed to remove the issue with the stalling by modifying the lwipopts.h file, more precisely: Modified the TCP_WND which is the tcp receive window. If set to high the download will be quicker but it can stall.Maybe there is a disbalan...

Hello everyone,Just an FYI, I added the clean data cache for the packet buffer which is sent over the UDP right before sending and that appears to have fixed the issue (for now, at least).Now, the initial packets and all the others that are sent out ...

Hi Bob, I've tried changing the MPU settings but it didn't help.I'll check the discussion.

Also, the data is correct if the delay is applied.

The buffer is static and it is only changed there, so that shouldn't be an issue.

First UDP packet sent contains all zeroes in the payload, second packet has partially false values in the payload, all the other packets that come after have correct payload. Why does this happen with the first packets?

ETH_DMACSR_RBU error occurs and stalls the Ethernet receive on STM32H7. Is there a way around this issue with the DMA?

Difficulties pinging the STM32H7 which uses LwIP and FreeRTOS. STM32H7 can send the UDP packet to the server but the server cannot send UDP packet to the STM32H7. I cannot ping the STM32H7, what could be the cause here?
