05:59 <narmstrong> hexdump0815: yes, if their secure boot is well done, it’s impossible

06:00 <narmstrong> But some guys managed to get usb boot working on the Amazon fire boxes, did you try ?

07:48 <hexdump0815> narmstrong: no did not try - do you have a link? worst case i can still uses with the balbes150 u-boot scripts and chainloading which works fine

07:51 <hexdump0815> its just that that way one always has to protect quite a big region at the beginning of the emmc from changes so that the legacy u-boot still finds its dtb etc.

07:51 <hexdump0815> with native mainline u-boot one can simply wipe the emmc and use it completely :)

07:53 <hexdump0815> narmstrong: btw. is hdmi output and usb kbd input in u-boot supposed to work flawless on g12a, sm1 and gxm? on gxl i had to disable serial input to make it work reliable due to noise from serial otherwise

08:10 <hexdump0815> maybe this is just a grounding issue, missing resistor or capacitor on the board issue - i have an amlogic and a rockchip box where simply soldering 15cm cable to the serial connector let the legacy u-boot stop early on

08:10 <narmstrong> hexdump0815: can't answer, I haven't tested enough

08:11 <narmstrong> I assume it's the same...

08:11 <hexdump0815> if i connect the cable to a properly powered usb-serial adapter it works perfectly fine

08:12 <hexdump0815> and with mainline u-boot it was similar: it was mostly working without serial soldered but failing often with a serial cable connected but not connected to an usb-adapter, so just hanging in the air

08:13 <narmstrong> hexdump0815: on which boards ?

08:13 <davor> hi, is there any news regarding NPU support on mainline kernel versions? specifically, I'm interested in the A311D SoC

08:13 <hexdump0815> narmstrong: tv boxes - so nothing proper :)

08:13 <narmstrong> yeah these boxes are crap

08:14 <narmstrong> davor: it can work

08:14 <narmstrong> I haven't personnally tested

08:16 <hexdump0815> narmstrong: did you see this one back then btw.: https://freenode.irclog.whitequark.org/linux-amlogic/2020-07-24#27574971

08:16 <narmstrong> but it has on AOSP with mainline linux (same driver) => https://android-review.googlesource.com/c/kernel/hikey-linaro/+/1416291 and https://android-review.googlesource.com/c/kernel/hikey-linaro/+/1327340

08:29 <davor> nice, thanks narmstrong. where did these files come from? I thought there were only blobs

08:29 <davor> couldn't find anything on amlogic's webpage

08:30 <narmstrong> davor: you can get the package on khadas website to use on their board

08:30 <davor> ahh, from here? https://www.khadas.com/npu-toolkit-vim3

08:31 <davor> I'll give it a shot and read those android commits, thank you
