06:36 <f_> zsoltiv_: hmm not AFAICT

06:37 <f_> The S805 datasheet could still be useful though.

06:38 <zsoltiv_> i guess so, if i cross-reference it with their kernel and u-boot sources

06:39 <f_> Yup. I guess neither HK, nor Khadas have leaked the S812 datasheet.

06:42 <zsoltiv_> f_: a real shame, but thankfully i only need enough to get u-boot to work, linux has mainline support already

06:45 <f_> zsoltiv_: IIRC xdarklight is working on those 32-bit SoCs

06:47 <zsoltiv_> f_: i'll hit him up then, once i'm home. would like to help out if it means i can resurrect my ancient board that's collecting dust

06:49 <f_> No idea if he works on u-boot too though....

06:49 <f_> *u-boot support

07:17 <zsoltiv_> can you even boot arm socs using something other than u-boot?

07:32 <narmstrong> I don’t think xdarklight started working on s805 support for u-boot, but patches are welcome :-) basic boot with serial and network should be easy since it would use already upstream drivers, only the -mx bits in mach-meson should be needed

07:44 <xdarklight> zsoltiv_: narmstrong is right, I've not touched u-boot on the 32-bit SoCs so far. and indeed, S805 and S812 have a lot of similarities (only tiny details are different)

07:49 <zsoltiv_> xdarklight: okay, i'll start hacking on it then

07:51 <zsoltiv_> narmstrong: thanks for the pointers

08:33 <xdarklight> zsoltiv_: nice. since I don't know which board you have: keep in mind that we don't have a (working) upstream NAND driver in Linux. The driver works for newer SoCs but last time I played with it on the 32-bit SoCs there were some bigger (memory corruption) issues. eMMC is much easier in that regard ;)

08:43 <zsoltiv_> xdarklight: i have an outdated MXIII android tv box thingy, for now i just want to get u-boot working, but i wonder if the board can even boot from an sd card

11:21 <zsoltiv_> narmstrong: are the -mx bits even needed? they seem to be doing things with arm trustzone, but i don't see any u-boot code touching that in other socs' sources

11:23 <narmstrong> zsoltiv_: by -mx bits I was meaning the S805 & similar specific code, as we did in arch/arm/mach-meson

11:25 <zsoltiv_> oh i see

11:28 <zsoltiv_> sorry, i'm very new to this

12:02 <f_> minute: Thanks a lot!

12:39 <minute> f_: great!

16:05 <f_> minute: indeed! I'll test it now.

16:07 <f_> G12B:BL:6e7c85:2a3b91;FEAT:E0F83180:402000;POC:F;RCY:0;EMMC:0;READ:0;CHK:1F;READ:0;CHK:1F;READ:0;CHK:1F;SD?:0;SD:800;USB:8;

16:07 <f_> Seems to work!

16:09 <f_> And...nice! I have download mode exposed via USB-C!

16:11 <f_> nice it also has eMMC flash :)

16:12 <f_> now...the ultimate question...how do I safely remove the CM4? :P

16:17 <f_> Honestly, what a tiny module.

16:18 <f_> First time I'm using an RCM4 clone (I also never used RPI CMs)

19:40 <f_> I wonder if mainline TF-A works on g12b...
