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?
