ChanServ changed the topic of #aarch64-laptops to: Linux support for AArch64 Laptops (Asus NovaGo TP370QL - HP Envy x2 - Lenovo Mixx 630 - Lenovo Yoga C630)
<steev> i'm not sure about the novago, but for the yoga c630, i had to get it from lenovo and create it on another machine
<hightower2> did you have to have some account/be part of a program or you just emailed them and they sent it?
<hightower2> but really they are such jerks for doing this... what's more, if I go to the model page on asus website, and search for 'reinstall' in faq, it gives me standard reinstall faq, non-specific for arm, which obviously doesn't work
<steev> had to do an account, and it was some request page that i don't recall
<steev> but again, that was lenovo

<steev> bamse: robclark: (anyone else from back then) - found a motherboard on ebay that had pictures - https://i.ebayimg.com/images/g/07IAAOSwKMJh5hqY/s-l1600.jpg looks like an ene kb9022?
<robclark> oh, is that the EC?
<steev> maybe
<steev> what is crazy to me, are some of them on ebay (motherboard only) going for 255+
<bamse> steev: very interesting
<steev> i found a schematic for 9022 on the badcaps forums, but it's for an acer and not sure if it's the same chip but no datasheets
<bamse> steev: do you know if we have the firmware for that thing laying around somewhere?
<steev> i don't think so, nor do i know where it would even be
<steev> maybe in one of the firmware update packages from windows?
<bamse> i just think i got an upgrade to it one of the times
<bamse> right
<steev> hm
<steev> unless it's part of the bios firmware itself, i don't think so?
<steev> the top 2, 9UCN23WW.bin (old) and 9UCN33WW.bin (new) are the BIOS firmwares
<bamse> hmm, i wonder what "bios firmware" would imply on this machine
<bamse> some uefi app perhaps?
<steev> it is
<robclark> I'd expect the EC to run before the AP is powered up.. maybe they use uefi capsule update to update the EC fw, but I guess the fw itself lives on some spi flash part or something like that? Or maybe it has it's own builtin flash?
<steev> yeah, it's definitely an efi capsule to update it
<steev> iirc, it updated the bios, and then rebooted to update the ec firmware
<steev> there is an "ecb.bin" in the efi bin file
<steev> it's ~128KB
<bamse> robclark: at least the kb9012 seems to have builtin flash...but yeah there must be some mechanism for bios to upgrade that thing
<bamse> steev: looks promising
<bamse> steev: so perhaps we can figure out how to drive the keyboard backlight pwm as well? ;)
<steev> https://www.file.io/download/osKpK2uEzleF - there's the ecb.bin file that i pulled out of there using uefitool - it just shows up as data, and i'm not even sure
<steev> apparently only 1 download is permitted at a time on that site, but sadly, while i've been on vacation, my boss redid some things on my server, so i can't just scp the file onto it
<steev> fwiw
<steev> steev@limitless:~/temp/BIOS/9UCN33WW$ ls /media/steev/Windows/Windows/System32/DriverStore/FileRepository/9ucn33ww.inf_arm64_f79a8fd87b4179a6/
<steev> 9UCN33WW.bin 9UCN33WW.cat 9UCN33WW.inf
<steev> steev@limitless:~/temp/BIOS/9UCN33WW$ ls /media/steev/Windows/Windows/System32/DriverStore/FileRepository/9ucn23ww.inf_arm64_3bf050869f63eb56
<steev> 9UCN23WW.bin 9UCN23WW.cat 9ucn23ww.inf
<steev> they're also apparently available in $WINDOWSDIR\Firmware\$FIRMWAREID\
<steev> just the .bin files
<steev> the biggest problem though, is "knowing" it's a kb9022... doesn't really help me, because i'm not smart enough to know what to do with that information
