I know Sandisk is good, but I need a bunch and price starts to add up. Actually I tried some of those tiny Sandisk USB drives that were not working well at all, lots of kernel panics. I got some PNY microSD that are working well so far.by Sc30 - Debian
The card will boot in various uhs modes up to ddr50, but only when it wants to. It is not reliable. It will only boot in the Samsung adapter. It is very picky. Never had a problem on the laptop so may be a uboot issue, but I am going to get different cards.by Sc30 - Debian
Well I got it to boot by manually setting the mode. So far it is the only mode I tried that works.

They are Micro Center branded cards and unbranded adapters. I don't know who the OEM is. I have also tried a Samsung adapter.by Sc30 - Debian

Ext3, everything same as working card. Obviously it is able to read something as it gets the correct image header information, but fails to read the whole image.

New cards are not cooperating at all due to read failures. No problems when using laptop to format and copy rootfs. Googling for "ext4fs_devread read error - block" shows other similar issues, possibly something with uboot mmc driver. I guess I will try different cards.

Thank you, it works. I bought some new SD cards and unfortunately they are giving kernel CRC error when trying to boot, doesn't matter which kernel.by Sc30 - Debian
Any new thoughts on this? Maybe ask on the lkml? I can use the old kernel but would like to figure it out.by Sc30 - Debian
I can't explain why your box works, are you sure you are running 6.5.7 on it? I don't think it has anything to do with the card itself. I get the card detect with the dummy card at the same time as a real card. This is booting 5.13.6 from USB with a dummy card: [ 18.641056][ T7] mvsdio f1090000.mvsdio: Got CD GPIOby Sc30 - Debian

Well something has to account for the difference in mmc bringup and it seems eerily similar to that usb problem.by Sc30 - Debian
I decided to try Debian 5.13.6 kirkwood and it works even on class 4 card, so I think probably a kernel configuration problem.

Hmm. I am still confused as why your CD is coming so much earlier. Even when I put a dummy card (just plastic) in the slot I get the CD but still not until 32 seconds, after hotplug is started. Do you have pogoplug V4 or Mobile? Mine is Mobile. Can you post your whole boot log? Starting hotplug events dispatcher: systemd-udevd. Synthesizing the initial hotplug events (subsystems)...done.by Sc30 - Debian
Thanks for the information. Are you running the same kernel on your pogo v4? What is the mmc driver doing that is dependent on the speed of the card? Shouldn't the card detect come before the card is even initialized?by Sc30 - Debian

Yes that is how I did it. Same procedure with a usb stick and it works. I just found an old 4gb class 4 card and got the same result.by Sc30 - Debian
It results in around 10 more lines of Begin: Running /scripts/local-block ... done But ultimately same result.by Sc30 - Debian
The partition label is rootfs and the sd is the only drive connected. Here is the log. Thanks.

I am unable to boot 6.5.7 Kirkwood Debian rootfs off of a 32gb class 10 SD card on a pogoplug v4. The error is gave up waiting for root file system device after waiting at least 10sec. Is this due to a slow card or other problem? I can boot the same system off a 4gb usb drive. I don't have any other cards to try right now. Thanks.by Sc30 - Debian
