<naoki> macromorgan: hello
<naoki> macromorgan: you are using rk3566 devices, right? then, are you using mainline u-boot to boot vendor/mainline kernel?
kevery1 has joined #linux-rockchip
<macromorgan> correct
<macromorgan> A-TF and the ram init is still handled by blobs, but everything else is mainline

<naoki> I tried but kernel didn't boot. I think my procedure to make u-boot image is not correct
<naoki> make CROSS_COMPILE=aarch64-linux-gnu- xxx_defconfig all

<naoki> ./tools/mkimage -n rk3568 -T rksd -d ~/rkbin/bin/rk35/rk3566_ddr_1056MHz_
<naoki> v1.13.bin:spl/u-boot-spl.bin idbloader.img
<naoki> oops
<naoki> ./tools/mkimage -n rk3568 -T rksd -d ~/rkbin/bin/rk35/rk3566_ddr_1056MHz_v1.13.bin:spl/u-boot-spl.bin idbloader.img
<naoki> then i flashed idbloader.img and u-boot.itb
<naoki> I guess I need to set BL31=path/to/bl31.elf before make all?
Tenkawa has quit [Quit: Was I really ever here?]
<robmur01> yes, if you don't have a BL31 you're going to have a very bad time as soon as anything makes a PSCI call. Doesn't U-boot throw a warning about that? (in the middle of a bunch of other output where it's easily missed, IIRC)

<naoki> I think I tried with BL31 and got some problem... but it was in the middle of trial & error, I might be confused
<naoki> I'll try it again. thanks anyway!

<naoki> btw u-boot/doc/README.rockchip should be updated ;)

<naoki> U-Boot SPL 2022.10-rc4-00001-g043944d182 (Sep 06 2022 - 22:47:44 +0000)
<naoki> then hanged... hmm...
<naoki> Trying to boot from MMC1

<naoki> macromorgan, robmur01: which bl31 are you using? mine is rk3568_bl31_v1.34.elf

<naoki> I rebuild idbloader.img with ddr.bin by hand. I just use u-boot.itb built by make all (with/without BL31)
<naoki> with BL31, u-boot hangs(?) just after SPL. without BL31, it reaches u-boot prompt, it can load kernel etc, but it hangs just after starting kernel
