<tomeu>
narmstrong: the power sequence seems to be pretty solid on the vim3 basic I have on my desk, but 50% of the time the boards in our LAVA lab hang when etnaviv probes
<tomeu>
do you know what I could have got wrong?
<xdarklight>
tomeu: at which stage does it hang? random guess: maybe the bootloader is different between the two boards - there's some magic blob for DDR initialization in it
<narmstrong>
tomeu: no idea, but yea what's the difference between the boards ? can you check the early boot log and the board type/version ?
<narmstrong>
and at some point you should get rid of the vendor u-boot :-/
<narmstrong>
tomeu: do you use the same kernel ?
<tomeu>
this was with the same kernel build, yeah
<tomeu>
let me check the logs before the kernel starts booting
<narmstrong>
probably the boot image of the CI VIM3 should be updated

<tomeu>
narmstrong: something I don't understand is that the board on my desk is showing 2GB available after boot, but the bootloader logs mention 4GB (and I should have purchased a VIM3 Pro)
<narmstrong>
tomeu: it may happen with vendor u-boot not updating the dt correctly

<lvrp16>
Speaking of u-boot and LAVA. Did u guys see the u-boot wget patches? Does open interesting applications but also a huge attack surface especially if people don't have a process to check signatures.
<lvrp16>
Give users just enough rope to hang themselves.
<narmstrong>
If it's only enabled for CI u-boots, I don't think it's worse than tftp or smb...
<narmstrong>
indeed they removed all pages on spi flash boot
<narmstrong>
the safest would be the flash the current bootloader on emmc, then try to replace the one in SPI
<tomeu>
narmstrong: because if something goes wrong with the one in SPI, the board will fall back to emmc?
<narmstrong>
If the binary is invalid yes
<narmstrong>
If it’s broken, no
<tomeu>
narmstrong: and the same images that can be booted from SD can be used to boot from SPI or eMMC? (sorry to ask, but I'm not finding any docs for mainline u-boot on internal storage)
<narmstrong>
The same boot binary will work from sd emmc or spi
<narmstrong>
But you’ll have to extract the boot binary from the sd or emmc image to flash it on spi
