Hello,
I'm using the RM48 HDK Development Board trying to use the SD card.
I've inserted an SD card, ran the RM48 Hercules Demo that came with the board in CCS5, opened my terminal program, typed the command:
*001000!
to run the SD card alert / SD card Init, and it always returns:
*VALID#! 00000000
which the code tells me represents an initialization failure.
When I check the signals out of the SPI2 breakout, I see the CS line, MOSI, and MISO all have some sort of signal (I believe the MISO line could be interpreted as having a high/all FF's and the a low/stop bit).
What am I doing wrong?
Regards,
Griswald Brooks
*** Also, though it changed no symptoms, I noticed a bug where in the demo the SDC_init() function pinmux's SPI3 instead of SPI2 ***
