Hi, any experience with the newest sdfat (multiple cards support) and two sdcards connected?
Thx.

No, I don't have a board with 2 sockets. Yet.
The first build only supports 1, the 2nd had incorrect uSD socket pinouts.
Have Rev 2 designed, but no cards purchased. Will handlle one of SD or uSD on either side of the board.

Suppose I could try an Adafruit shield for a 2nd one as a test.

Meh bootloader does not work:
Code: [Select]
avrdude: stk500_getsync(): not in sync: resp=0x00

Actually my device is 8MHz so I installed WinAVR and compiled bootloader code (from brewtroller) but no avail...

Programmer is FTDI breakout.

EDIT: Turns out common ground is needed for board and ftdi breakout. Also I attached 8Mhz bootloader which works at baudrate 38400.

Call me blind, but i cannot find the PCB layout for this exact board:



It's wonderfull, and i would like to toy a little with the layout ;-)
