FAT 16 NOT FOUND

[twenty]

I am using the mikromedia board for xmega. Board is the first board released (not rev 1.1). I have loaded the example program for mmc from the libstock. I continuously get the above error. I have tried a number of different micro SD cards. The SD cards were checked with a note book and they all work fine. The mikromedia display is also working fine. Is there someone that would be able to assist in getting the MMB to read the card?

Thanks and regards

I have found the problem!!!!!!!!! The schematic of the MMB shows that the SD Card is connected to PortC. This is not correct!!!!! The SD socket on the MMB is in fact connected to PortD. I got the hint from the resource code in Visual TFT.

Mikrobasic, could you please update the schematic for the MMB (mikrobasic AVR Xmega) and also the example code in Libstock

Thanks and regards

Hello,

schematic that can be found on web page, is the schematic of the last board revision.
There has been some pin out changes between revisions.

We can send you schematic for your board revision, just tell us which is your board HW revision.
The same thing is with LibStock examples.

Did you solve your problem regarding MMC example?

Best regards.

Thank you for your prompt response

I had a closer look at the board. It is HW Rev 1.10

The SD card on this board is connected to portD

Yes, SD card is working fine now after changing the example code from SPI, portc to SPI, portd
