SPL+UBOOT to boot the kernel. uboot version is 2020.01

[User.44]

The kernel cannot be started in a loop, as long as I use TF-A+UBOOT to start the kernel

Hi @文�?� �?​ ,

Can you please further clarify your context.

I understand you are using V2.0 ecosystem version.

Using Uboot SPL ( aka Basic boot no more supported ) or TFA+Uboot ( trusted boot ) ?

Did you use Distribution or Developper package to build your image ?

What customization did you do from default provided sources ?

Which HW ? ST board or custom ?

Thx

Olivier

I am in the uboot code. Use the configuration file stm32mp15_basic_defconfig. Compile SPL and uboot. Then replace flashing to SD card to start, the following situation will appear

Stuck here, will not boot the kernel

STM32MP157C-DK2

Hi @文�?� �?​ 

From ecosystem V2.0, "basic boot" is no longer supported. Uboot SPL can no longer boot the kernel.

Cf https://wiki.st.com/stm32mpu/wiki/STM32MP15_ecosystem_release_note_-_v2.0.0

You have to switch to Trusted boot chain.
