Yocto Image for H3ULCB+Kingfisher M04

What is the best way to create a Linux Yocto (preferably 3.21) for the H3ULCB+Kingfisher M04 configuration?

I tried the build instructions from here, but the image doesn't boot: https://elinux.org/R-Car/Boards/Kingfisher#Build_image

During the Kernel startup I get a panic:

[ 1.531217] loop: module loaded

[ 1.537959] renesas-rpc ee200000.rpc0: using DMA read (dma0chan0)

[ 1.544521] Bad mode in Error handler detected on CPU1, code 0xbf000000 -- SError

[ 1.552007] Internal error: Oops - bad mode: 0 [#1] PREEMPT SMP

How can I build a Image which supports the Kingfisher features (especially 8ch. audio and USB3.0): https://elinux.org/R-Car/Boards/Kingfisher#S.2FW_support_status

Hello,

I confirmed that Yocto v3.21.0 is booted on H3ULCB(ES2.0 8GB) + KF(M04).

I checked your boot log, and noticed IPL and U-boot is old.

So, please update IPL and U-boot, then try to boot again.

Best regards.

Thanks for your help!

I have to admit that the boot log from the link above is not mine (just the error was the same).

My u-boot and IPL is newer, here is my full log of the kernel Oops: https://pastebin.com/wiXmDzxz

It is a dual-boot system which can also boot Android (for development), so the bootloader is from the Android build. I hope that's not the problem?

Here is my u-boot environment: https://pastebin.com/qqw8cJJS

Sorry, I have never used android on H3ULCB + KF.

But, I tested Yocto v3.21.0 on H3ULCB(ES2.0 4GB) + KF(M04) again.

And I confirmed that it works.

How about using yocto bootloader ?

if yocto can be booted, android bootloder may not be good for yocto...

Best regards.

Thanks for your help Y.H. With the Yocto-Firmware it boots as expected.

How I need to get the Android part working again, but boota is not supported in the Yocto's u-boot. But that's a different story now.

Hello,

I prepared android 9 for H3ULCB(ES2.0 4GB) + KF(M4), and tested for booting yocto.

In my environment, yocto was booted with android's IPL and U-boot.

If you use old version of android, how about updating it ?
