Update for OpenSTLinux 4 (Kirkstone) #8

Open piratecarrot opened 2 years ago

piratecarrot commented 2 years ago

Should be updated for the latest OpenSTLinux

arduzilla commented 9 months ago

Indeed, but they do not care

mingzhangqun commented 3 weeks ago

We are actively upgrading.

rhaberkorn commented 3 weeks ago

I was using the patches from this layer successfully with Hardknott. Now I am trying to upgrade to Scarthgap. Let's see whether this works out. They changed a lot in meta-st-stm32mp. Perhaps I will also have to go back to 4.x after all.

mingzhangqun commented 2 weeks ago

Yeah, I'm working on mickledore. When I'm done testing, I'll release it.

rhaberkorn commented 1 week ago

@mingzhangqun Are you using the optee boot scheme? I was using "trusted", but they removed it beginning with 4.0. Still struggling with the migration to optee.

mingzhangqun commented 1 week ago

@rhaberkorn Yes, I'm using optee.

rhaberkorn commented 1 week ago

Yes, I'm using optee.

Do you have it already booting into u-boot?

mingzhangqun commented 1 week ago

Yes, I'm using optee.

Do you have it already booting into u-boot?

I'll do it this week.

@rhaberkorn I'm still working on mickledore, and I'm having some issues, and they'll be resolved as soon as possible. Image

Interesting, I had a very similar panic:

This was on Scarthgap and the device tree is heavily modified compared to the Odyssey SOM, but I didn't touch the I2Cs. This is completely left as in stm32mp157c-odyssey.dtsi. The panic in both cases appears to be somehow linked to i2c2 (i2c@40013000). But I cannot exclude the possibility that I did some kind of mistake when I ported it. Especially, "exti_pwr" referenced in pmic, which is also on i2c2 no longer exists.

You can get the backtrace by adding EXTRA_OEMAKE += "CFG_UNWIND=y". There is a script in optee for analyzing the backtrace. That's where I stopped and would continue debugging.

I have solved the optee boot problem. This is mainly due to optee's lack of I2C clock support. You can try it with this commit, and I will push it later after I finish testing.
