08:34 <mps> mszyprow: u-boot on my peach pi is 2020.01-rc3 and not 2020.04

08:35 <mszyprow> mps: good to know that such recent uboot still works on chromebooks :)

08:36 <mszyprow> mps: maybe I will check it if I have too much free time ;)

08:36 <mszyprow> mps: does the kernel config change helped to boot v5.9?

08:37 <mps> mszyprow: just installing it, will know in few minutes

08:41 <mps> mszyprow: no, even with CONFIG_THUMB2_KERNEL=y removed it doesn't boot though it now goes little further

08:47 <mps> mszyprow: one note about u-boot, I use extlinux.conf (not boot.scr) for it to have numerical boot menu, and it doesn't recognize 'FDTDIR' directive correctly

08:48 <mps> I must specify dtb file with 'FDT /dtbs-5.9.1-2-peach/exynos5800-peach-pi.dtb'

08:49 <mps> mszyprow: in a few hours (when finish some $day_job tasks) I will start with exynos_defconfig and see what will happen

12:56 <mps> mszyprow: 5.9.1 boots and works now. I should run 'make listnewconfig' on every major kernel build

12:57 <mszyprow> mps: while config did you miss?

12:58 <mps> I used config from 5.7 and on it build 5.8 and 5.9, and that didn't worked

13:02 <mszyprow> mps: btw, I didn't know about listnewconfig target

13:03 <mszyprow> mps: I always use make olddefconfig when I switch between releases and want to preserve modified .config

13:03 <mps> mszyprow: 'make help' will tell

13:04 <mps> also helpnewconfig, more helpful

15:36 <mps> on peach pi now when kernel 5.9 works I made new u-boot (2020.10) but machine says it can't boot from external devices (mmc in this case)

15:37 <mps> I'm sure that I enabled that and it worked when I recreated filesystem and tested boot from external devices

15:38 <mps> but looks like it after some time it 'reset' this (but boot fine from internal emmc)

15:40 <mps> cumbersome solution is to backup emmc, boot in chromeos recovery, reenable boot from external devices, restore to emmc

15:40 <mps> but, I hope someone know 'trick' how to enable boot from external devices from linux
