AI-64 - SD Problems

General Discussion
1

I’m wondering if I may have a hardware issue here, maybe someone would know what to check.

I have been using SD cards while messing around with anything that may cause problems with booting.

I have tried 4 cards, all good quality and am getting problems booting from the cards, sometimes fine, mostly issues.

The first sign of problems is an issue reading the status registerL

Gave up waiting for root file system device.  Common problems:
 - Boot args (cat /proc/cmdline)
   - Check rootdelay= (did the system wait long enough?)
 - Missing modules (cat /proc/modules; ls /dev)
ALERT!  /dev/mmcblk1p2 does not exist.  Dropping to a shell!

or here is another card:

I have loaded the cards up on a ubuntu machine and checked the filesystems, no problems.

Anyone any ideas?

Hi @AndrewCapon , which brand of microSD, I’ve personally seen this issue with Samsung EVO microSD, i know TI has seen it with PHY microSD… The best supported ones seem to be SanDisk Ultra/Plus/etc…

I’m pretty sure it’s just a new SOC, with a new driver, and not fully 100% debugged with every brand of microSD’s…

Note… We may want to create a list of “broken” microSD’s…

Hi @RobertCNelson

The two Samsung Evo cards I have tried give the interrupt problem. (32 GB Evo and 128 GB Evo Plus), I can’t quite find the other one at the moment but it was a cheapo 16 GB card.

The first problem (mmc1: problem reading SD Status register) is on a Toshiba Exceria 64gb which had been working perfectly. I have just re-flashed this and it is now booting ok.

I would like to copy my emmc to this card, I notice /usr/sbin/enable-beagle-flasher. Do I just copy /etc/beagle-flasher/bbai64-emmc-to-microsd to /etc/default/beagle-flasher and run that script?

Cheers

Andy

exactly!

5

Sorry should it be beagle-flasher or enable-beagle-flasher?

6

enable-beagle-flasher : just set’s it up do on the next bootup…

beagle-flasher : do the flash right now…

Regards,
