I have an issue with an SD card that works fine with USB Power but fails after a while under 5V Power.
I understand that the B**3 runs “Faster” with 5V Power sources. I can see the performance bump.
Is it possible that an SD Card works only at the “Slower” Card Clock?
I have tried a few cards and only this 32G SD has these issues. It is the best card I have for a “ROOT” card so I want more information on what to get to replace this “touchy” card with a solid performer.
I have the Latest Updated Beagle Board Black Angstrom OS Update.
What I wanted to do was “expand” the ROOT from 1.9G ==> 32G so I can work on some python code that needs more room. The DD of the OS went well and the “expand2fs” was fine. The “FSCK -f” passed OK.
What I was seeing is that over a “few hours” the OS hung when I was on 5V Power, and worked on USB Power. The performance on 5V power is great, so I did not want to loose that level.
What changes are needed to just use an “external USB Disk” as the ROOT? That would fix by problem also… I could just use an external USB as the “expanded” root for my development.
uENV looks like the place to start, but trial and error will take a long time. Any help here?
The Goal is a DEV Platform with 10’s of G free space to build my project on the ROOT.
