  • I'm also having problems with SD card init starting with v1.5 firmware.
    Some cards don't work at all; others only sometimes.
    Getting the serial port spitting out messages at 115200, I see a variety of bad responses, "no SD Card detected", "Failed Reading Header" and - my personal favorite - "sd_raw_read borks"
    If I get this working, my next question is about turning the GGA message back on. Since the parsing routine is in there - is there any reason this shouldn't work witht he EM-408?

  • Powerful little board!
    I had to read the source to figure out which of the UARTs to use. Unless I missed it, the datasheet does not explicitly tell you to use the UART0 pins. My first guess was that that was reserved for debug and ISP programming.
    Let me add my vote for new hardware features:
    RTC Vbatt pad option
    more pads for currently unused pins if there is room
    On the software side, mixed UART and ADC (I know, just a few lines of code I could do myself...) and RTC support.

No public wish lists :(
