please post brands of card you found sucess or failiure.
transcend 2gb 4gb 8gb-hc all work well with my a13 and 233
sandisc 4gb was not seen by the a13 at all with any image, but ran on 233 with 2gb image.
please post findings and sticky this post to stop others wasting their time with lame/incompatible cards
I've used these with success:
Kingston 4GB class 4 (very slow)
Lexar 4GB class 4 (nice and fast)
Samsung 2GB (from Olimex)
Sandisk UHS-I 16gb card works very well, particularly given the high I/O issues on this board.
