Installing Ubuntu 20.04 (Focal) with BSP uBoot with deep sleep and sound

[Syonyk]

Do any of you who have had this failure have a serial adapter you can plug and get the boot logs?

Is there a reason you're putting Fedora stuff in the Ubuntu thread?

Sorry-I realize that this thread probably wasn't the right place to post that-I was just trying to be helpful. I deleted the post.

Before I jump in and flash to emmc just to end up borking something up with the emmc, is there anything wrong with just doing the sdcard? I have it running on on card now and was wondering if the building of the kernel section was meant just for the emmc or can it apply to both?

[Syonyk]

There's no reason you can't perform the various steps on the SD card, if you want to keep it running on the SD card.

Block devices and such will change - you'll want to put the BSP uboot on the SD card, not the eMMC, if you don't want to touch the eMMC.

Thank you, I'm still way rough around the edges, I assumed that the kernel on the emmc was used for both the os on the emmc and sdcard. Thank you for the tip on the bsb uboot.

I did read your other thread about it being worth while to buy an uart serial adapter and usb to emmc adapter. I have the one but just ordered the serial cable. Which is why I want to wait to flash the emmc.

When I get to the part of building kernel and I git clone the pbp-tools, after I cd into pbp-tools there is no pbp-build-linux-hwaccel for me to run ./pbp-build-linux-hwaccel or should I run ./pbp-install-linux? Or in the readme do I run each line under the **hwaccel:** section? Sorry for noobish questions.

That tool repo changes constantly. I'm pretty sure the pbp-build-linux now applies the hardware acceleration patches.

things are pretty settled now in pbp-tools. i was adapting all my personal scripts for shared usage, adding dependencies, and also working in $PATH. then merged several scripts that were similar.

i will write a howto document in the repo soon also.

you can build 5.7.0-4 and 5.8-rc2-3 with hwaccel patch. (default)

use HWACCELREL=none to build without the hwaccel patch. should work to build any 5.7 or 5.8 based kernel.

the hwaccel patches occasionally need to be rebased on newer kernels and can be delayed as is the case with 5.7.5+.

i included comments and override info in the scripts for a basic understanding of how they work.

In this tutorial the step that says to run ./pbp-build-linux-hwaccel I'll run ./pbp-install-linux instead and I should be able to continue with the give as written?

So upon looking at what was in the tools repo and what was being listed to run it seemed pretty straightforward. I believe I now have the latest kernel. Thank you for this guide.
