    163163=== Booting to a kernel/rootfs on the microSD ===
    164 This assumes the bootloader will remain on the eMMC, but then we switch to the microSD for the kernel/rootfs.
    165 
    166 Run the following commands in the uboot bootloader command prompt on the Newport SBC bootloader serial console:
    167 {{{
    168 
    169 #This sets the bootargs, make special note of the root = and adjust partition as necessary
    170 setenv bootargs 'cma=64M coherent_pool=16M net.ifnames=0 root=/dev/mmcblk1p1 rw rootwait console=ttyAMA0,115200n8 earlycon=pl011,0x87e028000000'
    171 
    172 #This loads the kernel file (Image) from folder boot (on microSD) into memory
    173 ext4load mmc 1:1 ${kernel_addr_r} boot/Image
    174 
    175 #This boots the board
    176 booti ${kernel_addr_r} - ${fdtcontroladdr}
    177 }}}
    178 
    179 Troubleshooting:
    180  * Use the ext4ls to confirm you can read the microSD and see the kernel in the boot folder
    181 {{{
    182 GW6304-B> ext4ls mmc 1:1 boot
    183 <DIR>       4096 .
    184 <DIR>       4096 ..
