stm32mp25: "EQOS_DMA_MODE_SWR stuck FAILED: -110" ethernet error in u-boot

[zakariazh]

Hello,
I am using the STM32MP257x-EV1 board with version 2022.10 of u-boot-stm32mp (with patch 0001-v2022.10-stm32mp25-beta.patch from commit dc5d7824 made on April 12, 2024).

When compiling u-boot + stm32mp257f-ev1.dts, only the eth2 interface is functional, the other interface displays the following error:

EQOS_DMA_MODE_SWR: mode: 00000000482c1000 - wait: 50
EQOS_DMA_MODE_SWR stuck FAILED: -110

After compiling u-boot-stm32mp, I used the dtc tool with u-boot.dtb to get my full dts file used and here is the configuration of eth1 and eth2.

Can anyone help me to solve this error ?

Thank you

Hi @zakariazh ,

Seems you are using old SW version (Alpha program).

I recommend first to take the official 5.1 version STM32 MPU ecosystem release note - stm32mpu

Hi @Olivier GALLIEN,

Thank you for your reply.

I am using Yocto and recompiled U-Boot 2022-10 from the mickledore branch (the latest version) and I still have this problem. Note also that I don't have this problem in linux when disabling the ethernet switch as described here https://wiki.st.com/stm32mpu/wiki/Ethernet_switch_device_tree_configuration#DT_configuration_example_to_transform_ethernet_switch_to_ethernet_standalone_at_board_level. (note that the mickledore version of u-boot disable it also)

Do you have any other ideas?

Thanks
