The USB interface is not functional, as we are in development, and have no idea how to use JTAG. SD card works.
I have been looking at this post:
https://community.nxp.com/t5/i-MX-Processors/About-quot-i-MX6-DDR-Stress-tester-quot/m-p/307472
=> dcache off
=> icache off
=> fatload mmc 0:1 0x00907000 ddr-test-uboot-jtag-mx6ull.bin
** Reading file would overwrite reserved memory **
So if I use loadaddr instead:
=> printenv loadaddr
loadaddr=0x80800000
=> fatload mmc 0:1 $loadaddr ddr-test-uboot-jtag-mx6ull.bin
66748 bytes read in 40 ms (1.6 MiB/s)
=> go $loadaddr
