Open2X Dr7 And Problems Detecting Sd Card

[darionapole]

I had this problem yesterday, i don't know if this is because of some dirt or someting silly, but just posting because it could be a driver bug.

Well, i inserted my 8GB Transcend SDHC Class 6 card and everything froze up. Tried several times, being always the same result. Until i removed the card, and it gave me and I/O Error and unfroze.

Here's the serial output:

...and it completely crashed.

Rebooted and it worked...

This is the second time this has happened to me in the month
Is this important or it's only some gp2x randomness? :unsure:

Welp, I actually use a Transcend 8GB SDHC card so it is probably not the driver, though the driver is not perfect.

Are you safely unmounting the previous card by pressing "X" in GMenu2X, waiting a few seconds, removing the card, waiting a few seconds, and inserting the new one? If not, try doing that of course.

Sometimes Linux on the GP2X just doesn't want to let go of a filesystem. So you'll try to unmount it and nothing happens to the icon on the bottom left. Then, if you try to insert a new SD card anyways, it won't work because now Linux is thoroughly upset and you need to reboot the GP2X. There's not much I can do about that, I spent quite a while working out how to do it best and I think this might be the best it'll get.

Yes, always unmount before removing, and every now and then, i check it with fsck just to be sure that it's not corrupted or something, but haven't got a problem since 2 months ago.

Now it's working but i'll try cleaning it with iso alcohol anyways
