I am able to build the bare-metal "sdmmc_sdcard" example for the SAMA5D2 Xplained Ultra board and download it to QSPI Flash using the SAM-BA 3.1.4 tool, but I cannot get it to run.
For information, I have successfully built, downloaded and run other examples, e.g., "getting_started" and "usb_hid_device" without issue. The only two differences I can see between all the other examples I have run so far and this one are:
- This example requires two blocks of QSPI Flash (the binary is ~90kB in size). All the other examples fit into one block, i.e., the binary is less than 64kB in size.
- This example runs from DDRAM, not internal SRAM. It should be noted that I have successfully run the "ddram" example, so the DDRAM itself should be fine.
Can anyone help?
