I have been trying to get an image to boot from sdcard by changing uboot cmd, but im not able to get other mmc devices diferent than mmc 0 to be detected:
Terminal ready
=> mmc list
dwmmc@ffcf0000: 1
dwmmc@ffd00000: 0 (eMMC)
dwmmc@ffc60000: 2
=> mmc dev 0
switch to partitions #0, OK
mmc0(part 0) is current device
=> mmc dev 1
Card did not respond to voltage select!
mmc_init: -95, time 10
=> mmc dev 2
Card did not respond to voltage select!
mmc_init: -95, time 9
I also double checked tf-card related switches and they are correct according to documentation. I suspect i need to recompile uboot and change the default boot config, but before that shouldnt uboot detect the sdcard in? how can i do this? is it possible?
