SD Card Weirdness

uConsole
1

Here’s a poser for you:
I flashed Trixie on a new 1 TB SD card using Raspberry Pi Imager v2.0.7 running on a Win 11 PC. Imager cleaned, wrote to and verified with no errors displayed. Then I put the SD card into uConsole and Trixie came up with all the initialization dialogs. Still good. Did a sudo apt update and full-upgrade and over 100 updates were installed. I installed build-essential, FLEX, and a couple other tools. No problem so far. I ran raspi-config and had it expand the filesystem. This causes a reboot to be necessary. I rebooted and Trixie came up fine again. I then shut down for the night. The next morning I turned on the uConsole and - nothing. No flicker of the screen at all. I waited about 20 minutes just in case Trixie was slow to boot but still nothing.

What happened??? Any ideas?

Beyond the usual bad card or corrupted files, no !. Do you have another card to try or something to put this one into to examine the structure or scan for errors ?. Try reseating it in the slot ?.

I’ve had zero issues with Sandisk cards, especially the Extreme Pro’s.

are you using a cm4 or cm5?

4

CM5. Does it make a difference?

5

This is a SanDisk Extreme Pro. I figured it must be good after passing the Imager compare test.

I have a 1Tb in the top slot just for removable file storage. A 256Gb as boot backup via the AIOV2 usb-c (sd card copier from the 256gb nvme, Rex’s Trixie updated almost daily)…

Are you using rexs new screen image?

8

you’ve obviously updated eeprom?

Where is the latest found? I got mine from a MEGA download

Yes. I have SD as the first try with NVME if the SD fails. I’ve tried it with the NVME both installed and out of the system and the SD card won’t boot.

Latest Trixie ?

Yeah think I got mine from his post…

SD_QUIRKS=1 set in the eeprom boot ?. If so have you tried booting from NVME and using the Trixie sd card copier (under accessories) ?.

yes, cm5 is picky about SD cards and sometimes fails to boot, updated eeprom and the config changes to slow the interface down for the initial phase make it more reliable

Well I don’t know how I did it but I got the SD card to boot every time. Now I’m trying to get the NVMe to boot Ubuntu and I hooked up an HDMI monitor to see why I’m not getting anything on screen. All I see are two lines (Spelling may be wrong. The monitor is very small and text is blurry.):
zswap: compressor zstd not available. using default lzo zswap: zpuol z3fold not available, using default zsmalloc

The upgrade was the issue; should have been sudo apt update && sudo apt dist-upgrade -y

dist-upgrade is more thorough than upgrade and more likely to mess things up by installing a mainline kernel instead of our custom one
