SD Card Reliability Problems

Former Member

I have been experiencing SD Card problems with 2 of the PZSDR SOMs. I would like to know if any other PZSDR users are having the same problem.

On one SOM, the unit suddenly failed to boot. I reseated the SD Card and the boot problem was fixed. The failure to boot later happened again (3 times total) and reseating the SD Card always returned the SOM to booting successfully. 2 times the SOM failed to boot on our custom carrier board and one time it failed to boot on the Avnet carrier board. Finally I replaced the SD Card and the boot problem has not returned so far.

On another SOM, the unit would boot, but Linux could not read the files on the SD Card (/mnt/mmc was empty) after boot 80% of the time. I changed to a different SD Card and the problem has not returned so far.

Thanks in advance for any info!

    Hi jlavie.

    1. your Samsung 32GB UHS-I is not a suggest SD Card solution, please look at section 4 of the SD Card advice document.

    2. I do not know the speed grade so i can no comment on if there should be an issue or not.

     

    Please refer to page 6 of that document and it contains a list of various proven SD Cards that I would suggest you choose from.
