18:55 <micken> maybe I should try mainline uboot :D

19:10 <anarsoul> I doubt it

19:10 <anarsoul> with bad ram timings you wouldn't get your code running

19:10 <anarsoul> but sure, try mainline u-boot

19:10 <micken> I thougt so

19:10 <anarsoul> come to our side

19:10 <micken> yes!

19:10 <anarsoul> :)

19:11 <micken> Is there a page about what to put where on sdcard?

19:12 <micken> I get this far:

19:12 <micken> Trying to boot from BOOTROM

19:12 <micken> Returning to boot ROM...

19:13 <anarsoul> micken: there's README

19:13 <anarsoul> also there's https://stikonas.eu/wordpress/2019/09/15/blobless-boot-with-rockpro64/

19:14 <micken> thx

20:14 <micken> problems: I usualy switch to aarch32 in cmd/boot.c but it just crash now with this u-boot, I also tried to make the "ROM" a uImage , but I don't know how to set it to non kernel ( that is not looking for atag etc)

20:14 <micken> anarsoul: or is tftpboot broken?

20:14 <hanetzer> blerp

20:14 <micken> anarsoul: with mkimage making it a arm32 image

20:26 <micken> ok , tried a testprogram now , same result

20:34 <micken> anarsoul: this is set: CONFIG_ARM64_SUPPORT_AARCH32=y

20:38 <micken> found the mkimag setting, but no luck

20:47 <stikonas> maybe nobody tested mainline with 32-bit?

20:48 <micken> perhaps

20:48 <micken> but code is there

20:49 <micken> bootm should be able to figure out from image type

21:38 <micken> CONFIG_ARMV8_SWITCH_TO_EL1 , added that

21:38 <micken> made no diff

21:46 <micken> line 355 in arch/arm/lib/bootm.c

21:49 <micken> ah just for linux

22:00 <micken> crash from this: armv8_switch_to_el1

22:01 <micken> anarsoul: I think mainline was a bad idea for me :D

22:06 <stikonas> micken: try 64 bit :)

22:06 <micken> no

22:06 <micken> :D

22:06 <micken> stikonas: feel fre to port riscos to arm64

22:06 <micken> could just port to x86

22:07 <micken> it would be as hard to do

22:08 <stikonas> well, yeah... probably quite a bit of low level assembly

22:08 <micken> and the SWI system

22:09 <micken> all will break down on arm64

22:11 <micken> Loading Standalone Program

22:11 <micken> "Synchronous Abort" handler, esr 0x02000000

22:11 <micken> oh so fun

23:20 <anarsoul> micken: sorry, no idea about 32-bit

23:27 <micken> anarsoul: ok , well I use blob uboot , I don't want to spend time with lowlevel parts of el switching in uboot

23:28 <anarsoul> :)

23:38 <anarsoul> mmind00: 5.4-rc6 also hits "WARNING: CPU: 4 PID: 1 at drivers/iommu/rockchip-iommu.c:530 rk_iommu_irq+0x158/0x368"

23:38 <anarsoul> and as result system doesn't reboot properly

23:46 <anarsoul> hdmi audio is broken in 5.4-rc6

23:51 <stikonas> hmm, 5.4 sounds a bit broken :(

23:53 <anarsoul> rk_iommu issue happens in 5.3 as well

23:54 <anarsoul> I can't get analog audio working either

23:54 <anarsoul> sound card is here

23:55 <anarsoul> 'alsamixer -Dhw:0' complains 'cannot load mixer controls: No such device or address'

23:55 <anarsoul> -Dhw:1 is hdmi and kind-of works
