Hi
<quinq>
Is it expected that the dhcp command does not update ipaddr/netmask in the env, after a successful (and applied) DHCP request?
<quinq>
Case is: env set ipaddr x.x.x.x; dhcp; env print ipaddr
<quinq>
This doesn't print the ip aquiried by dhcp, but the ip set manually
<mps>
quinq: IDK for sure but this look how it should work
<quinq>
I'm currently looking for a potential configuration option to allow dhcp/bootp command to set the env
<mps>
i.e. dhcp don't have to set any env var
<quinq>
ah :)
<mps>
well :)
<quinq>
But then there's no way to know the current network settings, is there?
<mps>
there is but I forgot what is command to list network parameters
<mps>
and don't have now any real board to check
<quinq>
Ah, right, I think I already had this point “clarified” last week, there's apparently a 'net' command in newer U-Boot, but not in my 2019 version…
frieder has joined #u-boot
<mps>
aha, yes. I forgot for it
<mps>
net list? maybe
<quinq>
Possible, but I won't be able to verify that ^^
<quinq>
Anyway, thanks mps, that's a bit clearer now
<mps>

I'm just started u-boot sandbox but it is new one 2024.04

one pointer of ubi internal data structures used in ubi_close_volume() points to an address outside of the physical memory, but why and why only in certain situations but not in others?

Kasreyn: some years ago Javier Canilas (then worked at samsung) explained to me how to do this for peach-pi but now this site where it is described doesn't exists
<mps>
iirc, it is done to use unsigned u-boot and flash it, but don't take my words seriously (writing from faded away memory)
<mps>
cah yes, looks like it is saved on archive.org. thanks for link

it mentions "servo method" but i want to use the XGecu Pro programmer since i have made a jig (wires sticking out of the Chromebook)
<mps>
yes, if you have external programmer I think it is safe. just make copy of original flash content if need to reflash to original
<Kasreyn>
so this cros_bundle_firmware script is what is needed? in the examples it is writing to SD card .. it can write a normal image?
<mps>
years passed and I forgot details. but with hardware device to flash chip on the board it is possible to flash anything
<mps>
ofc also it is possible to flash from booted OS with command flashrom iirc proper name of command
<Kasreyn>
so i recovered the device from brick (the eMMC is not responding) by unpacking and reflashing bios.rom from recovery image. it's basically just "losetup --show -f -P chromeos_12105.100.0_daisy_recovery_stable-channel_snow-mp-v4.bin" then "/mnt/usr/bin/chromeos-firmwareupdate --sb_extract directory"

but yes i made a backup before programming it (i heard it contains a serial number etc) it was already in developer mode not sure if CTRL+U worked before but it certainly did after flashing bios.rom

newer arm chromebooks have 8mb spi chip, no idea about ancient ones like snow
<ellyq>
i think it's safe to assume they have at least 2MB SPI though
<Kasreyn>
ellyq: snow has (4MB) W25Q32DW : 1.8V 32M-BIT SERIAL FLASH MEMORY WITH DUAL/QUAD SPI & QPI Winbond
<Kasreyn>
at least my XE303 has that chip :)
<ellyq>
Kasreyn: oh, then you should be able to just `flashrom -p internal -w image.rom`
<Kasreyn>
sure but i need to either build image.rom or download a prebuilt one :)
<ellyq>
well, defconfig should be sane for thet
<Kasreyn>
and it has to be a more recent version of U-Boot that supports bootz command
<Kasreyn>
the code needs to be signed though?
<ellyq>
no, BootROM on chromebooks never checks the signature of secondary payload
<ellyq>
s/never checks/doesn't check
<ellyq>
I'm currently working on u-boot support for MediaTek ones, so on MT8173, MT8183 and MT8186 i can swap the entire SPI image and have BootROM load it just fine without VBOOT or any other checks (though coreboot on MT8183 is currently completely broken)
<Kasreyn>
so would it make sense to make snow_defconfig then flash u-boot-dtb.bin directly to SPI chip?
<ellyq>
if you need zboot, i would do `make snow_defconfig` and then `make nconfig`, look for the options you want to add, save it and build
<Kasreyn>
very nice ellyq.. i have the Acer Spin 311 MTK.. want try that at some point :)
<ellyq>
Kasreyn: which one is that? kukui? corsola?

welp, sounds like you need to hook-up UART
