Hi,
In our custom which is similar to sabresdp imx6 quad core. In our custom board we have used imx6 solo instead of quad and also change the sd card slot from SD3 which is in sabresd to SD1 in our custom board. there is no eMMC card on our custom board. I am using LTIB build system. I would like to know what changes are require in uboot to fetch the kernel properly and in which file I need to set the defualt configuration. I have used make mx6solo_sabresd_config to build the uboot. I was able to run the uboot from SD card from sd1 but not able to load the kernel from sd1 following are the printenv log
bootdelay=3
baudrate=115200
ipaddr=192.168.1.103
serverip=192.168.1.101
netmask=255.255.255.0
loadaddr=0x10800000

ethact=FEC0
bootargs_base=console=ttymxc0,115200
bootcmd_msd=run bootargs_msd; mmc dev 2; fatload mmc 2 ${loadaddr} ${kernel}; bootm
bootargs_msd=setenv bootargs ${bootargs_base} root=/dev/mmcblk1p2 rootfstype=ext4 rw rootwait
bootcmd=run bootcmd_msd
stdin=serial
stdout=serial
stderr=serial
bootargs=console=ttymxc0,115200 root=/dev/mmcblk1p2 rootfstype=ext4 rw rootwait
please help me where I am going wrong.
