Migration from Linux 4.19 to 5.4 results in a non-booting system

[CErik.1]

Hello!

I see many having similar issues, but I have have yet to find a solution to the reason my boot is not happening.

ATF: v2.2-stm32mp-r2.1

U-Boot: 2021.01

Linux: v4.19-stm32mp-r3.3

Works just fine

ATF: v2.2-stm32mp-r2.1

U-Boot: 2021.01 (Edit: and v2020.01-stm32mp-r2.1)

Linux: kernel-stm32mp1-openstlinux-5-4-dunfell-mp1-20-11-12.tar.xz

Results in the kernel outputting the following (LL debug enabled with highest level)

[   0.398268][   T1] pinctrl core: initialized pinctrl subsystem

...

[   0.628638][   T1] bus: 'platform': add driver stm32mp157-pinctrl

...

[   1.831777][   T1] device: 'soc:pin-controller@50002000': device_add

[   1.838307][   T1] bus: 'platform': add device soc:pin-controller@50002000

[   1.845361][   T1] PM: Adding info for platform:soc:pin-controller@50002000

[   1.852543][   T1] bus: 'platform': driver_probe_device: matched device soc:pin-controller@50002000 with driver stm32mp157-pinctrl

[   1.864472][   T1] bus: 'platform': really_probe: probing driver stm32mp157-pinctrl with device soc:pin-controller@50002000

[   1.875802][   T1] stm32mp157-pinctrl soc:pin-controller@50002000: no pinctrl handle

[   1.883752][   T1] platform soc:pin-controller@50002000: Driver stm32mp157-pinctrl requests probe deferral

Then pretty much everything end up with "no pinctrl handle".

I prepared kernel-stm32mp1-openstlinux-5-4-dunfell-mp1-20-11-12.tar.xz by applying all patches and merged the config fragments. My DT is the DK1.

What am I missing?

Edit: I should add that I have tried the ST U-Boot with tag v2020.01-stm32mp-r2.1 with the same result.

Hi @Community member​ ,

Please confirm we can consider you are now using a consistent V2.1.1 OSTL ?

https://wiki.st.com/stm32mpu/wiki/STM32MP15_OpenSTLinux_release_note#v2-1-1

Between 4.19 and 5.4 dts structure has changed ? Did you align your DK1 DT on the 5.4 structure ?

Else can you share complete boot log ?

Sorry, my reply is on the wrong level.

[CErik.1]

I have modifications made to fit my board for ATF and U-Boot in the DT so that should be consistent with your release.

ATF: v2.2-stm32mp-r2.1

U-Boot: v2020.01-stm32mp-r2.1

For the kernel I now took version v5.4-stm32mp-r2.1 (e1b933d696) from https://github.com/STMicroelectronics/linux.git. I build with the

config from board/stmicroelectronics/stm32mp157a-dk1/linux.config and stm32mp157a-dk1 with the following modifications

Debug added to the .config and change of i2c-port for the pmic (if that even matters)

Complete bootlog (mmc not configured)

Boot log attached.

I am probably missing something trivial. Thanks for the help!

Hi @Community member​ 

Can you share your kernel DT ?

I'm also still interesting to get TF-A and Uboot traces ( prior to kernel traces )

Thx,

Olivier

[CErik.1]

Sure, again thank you.

I use https://github.com/STMicroelectronics/linux/blob/v5.4-stm32mp/arch/arm/boot/dts/stm32mp157a-dk1.dts with the modification to the i2c4 -> i2c2 as shown above for the stm32mp15xx-dkx.dtsi.

For the TF-A and Uboot I have my more complete DT (Ethernet + MMC + PMIC on I2C2), thus dirty.

Here is the traces
