on another forum post I found this info which may be useful before spending too much money on high speed SD cards?


--- Quote ---We use Transcend 8GB Class 10 for development.

Yet, don't bother to get sdcard with speeds over 25mbytes. The SoC won't handle anything above that.

Having just spent over $500 on vet bill for my cat, all plans to buy something have been put on hold.

from a separate sticky I see

--- Quote ---Board Won't Turn on
Few steps to follow:
1 - Check your power supply. See if its providing 5V when you turn the board on.
2 - Check your SD Card. Reflash the Image.
3 - Check the eMMC/SD Jumper
4 - DO NOT USE ANY KIND OF SD CARD ADAPTER. mini/micro to fullsize.

Now of interest to me, is for my allwinner attempt I did try sd card adapter so that advice might hold true to all devices?

In other words, if your micro/sd card slot is faulty, your adapter won't work either?

hmmmm

@aus9:  I've had lots of problems both with defective (regular-size) SD card readers and the cards themselves.  There seem to be a lot of fakes on offer out there. I've found that Class 10 cards are more reliable booters than class 4, and forget about class 2.  No read speed differences, just more predictable boot.  I finally bought a Transcend USB reader/writer that has been reasonably reliable in terma of producing usable cards, again on the 'big' SD cards.  Perhaps you could dd an image to your micro card in the device itself via android?  The android terminal apps I looked at were all pretty clumsy, but might work for a wget and dd.

I second that, been there many times.
Except I couldn't resolve whether the faulty part was the mmc-sd card or the usb adapter.
If it's not a problem, could you disclose where you bought your Transcend usb adapter?
