STM32MP157AAAC custom board. Ethernet works with ECO 1 & 3.1. Used CubeMX to a add ethernet. PHY provided clock to MAC. RGMII interface. 1000Mb/s2. Applied changes exactly as based on the WIKI and as generated by CubeMX to OP-TEE U-boot and KernelB...

This is a thread for your input how ST could improve providing known issues for example1. Update the WIKI2. Separate WIKI page,like this used on ST's Chinese website ?https://wiki.stmicroelectronics.cn/stm32mpu/wiki/Visual_troubleshooting_gridhttps:/...

Custom MP157AAA3 board. SD card formatted with ECO 5.0.0 using the SD tools using the files from the starter package. (including rootfs etc..) . Build the TF-A, OP-TEE (in SYSRAM), U-boot and kernel from the ECO 5.0.0 sources.Kernel generates the m...

on the left CubeMX generated for STM32MP157AAAC and on the right, dk1 dts included: stm32mp15-pinctrl.dtsi (kernel dtsi)The biases are reversed and the pin controls are in separate groups in the DK1 dtsi files. and the slew rates are diferent.i am w...

ECO sources used (not git). Custom board based on STM32MP157AAA3.Both when using OPTEE in DDR and SRAM this issue occurs.The kernel reports an "cut here" and then reports:[ 0.273935] Unhandled fault: imprecise external abort (0x1c06) at 0x97638f7aThi...

1. The WIKI is incorrect for Reset GPIO, it should have () around GPIO statements.2. The reset GPIO pin added.. et voila... the PHY now worked . IPv4 address ok3. The datasheet of PHY's PHY ID seem to mentioned a different ID than the ID read back...

Fixed, Wrong config of PHY (forgot to check the CLK125 in Cube-MX)https://wiki.st.com/stm32mpu/wiki/Ethernet_device_tree_configuration#DT_configuration[a] The wiki is ambiguous <STM32_PINMUX('G', 8, AF2)>, /* ETH_RGMII_ETHCK */This applies to 3.3.4 ...

Hello Bernard, about ideas. Don't want to interfere this discussion So Ill probably create one for it to that other can provide input as well.

Very interesting, the same error with a totally different reason ! Perhaps a way to prevent this is to only make changes using the USER sections of a DT and then let CubeMX make M7/M4 changes and then apply those to the DTs ?

Fixed after recreating the linux defconfig (default as per WIKI) and recompilation.
