Salut Bastien.

I'm facing the same issue with my Aura.

I tried to build a mmcblk1 bootable SD by copying the internal one (dd if=mmcblk0...) with its 3 partitions. But it did not boot.

I digged a little bit in the u-boot from firmware.
Looks like the U-boot parameters are set to internal SD (mmcblk0) first.
baudrate=115200
loadaddr=0x70800000
uboot=u-boot.bin
kernel=uImage
bootcmd_mmc=run bootargs_base bootargs_mmc;load_ntxkernel;bootm
bootcmd_SD=run bootargs_base bootargs_SD;load_ntxkernel;bootm
bootcmd_recovery=run bootargs_base bootargs_recovery;load_ntxkernel;bootm
verify=no
bootcmd=run bootcmd_mmc
bootargs_recovery=setenv bootargs ${bootargs} root=/dev/mmcblk0p2 rootfstype=ext4
bootargs_mmc=setenv bootargs ${bootargs} root=/dev/mmcblk0p1 rootfstype=ext4
bootargs_SD=setenv bootargs ${bootargs} root=/dev/mmcblk1p1 rootfstype=ext4
bootargs_base=setenv bootargs console=ttymxc0,115200 rootwait rw quiet lpj=3997696
stdin=serial
stdout=serial
stderr=serial
bootdelay=0

I guess we have to set bootcmd=bootcmd_SD.
But I don't know how to do that since I have no console and delay for interrupting u-boot and get the CLI is zero (bootdelay=0).

I don't know either how the order of precedence is managed by u-boot.

Could some expert help?

Thanks in advance.
