SD was detected once, never again #656

Open null-VOID-null opened 1 month ago

null-VOID-null commented 1 month ago

I have a dell Chromebook 11 3180 with a kefka motherboard, and I've recently installed the full rom uefi, and made made a bootable SD but it only detected once when I had put ventoy on it and then put the iso of ubuntu mate on it, and it booted with no issues. But then I used the sd to Install ventoy on a usb as well as an iso like I did with the sd, I did this because I wanted to install Ubuntu make to the SD like you would a normal storage device. Nothing went wrong with the Installation process. When I rebooted and tried to boot the sd however, it just wasn't detected. All I saw was ubuntu (probably from my internal storage), and my internal storage. I don't know why it only detected it once and never again nor how to fix it.

the SD card reader on Braswell is directly connected to the mainboard, and so has to be inserted at boot to be detected - it won't autodetect on insertion like USBs will. Unfortunately there's no good way to debug edk2 on Braswell, since there's no serial output. One would need a device with a Google servo header attached, or to solder 0.5mm pitch wires to the solder pads to get serial output and see what's going on

Ok then, well, I've done a bit if testing since I made this post, and it only really detects under these conditions:

Ventoy is installed on the SD

An iso file is on the SD

And it's the first boot after doing that. If I reboot it doesn't show up again.

So Im not sure if the issue is what you described, tho I could be wrong (and it is always inserted on boot btw) ((also, should I add the additional things I found to the post?))

does a warm vs cold boot make a difference in detection? "first boot' doesn't make much sense as a discriminating factor

I've only tried cold booting, so idk. And I can't test it because I currently have no access to said SD (currently using it for other, more important tasks that would be wiped if I tried to test it)
