Maybe there are same bug in STM32CubeMx creating mp157 decvice tree

JXu.5 · ‎2021-02-28

I use CubeMx creating stm32mp157 device tree.

After the 2nd create , the path "CA7->DeviceTree->[My board]->u-boot" always has a file named "<My board>.dts.bak" .
modified the Device Tree code in kernel (USER CODE), then push create. The u-boot dts will be replaced by kernel dts.

The CubeMx version is 6.2.0, the mp1 package is 1.3.0

Hi,

this is expected behaviour, see the following wiki article: https://wiki.st.com/stm32mpu/wiki/STM32MP15_device_tree#STMicroelectronics_software_delivery

The linux device tree files are copied to the u-boot device tree. The nodes used by u-boot usually have a 'u-boot,dm-pre-reloc;' in the device tree node.
