Device assignment:
mmcdev 0 = eMMC
mmcdev 1 = SD Card
1. Run the following commands in the Uboot shell to create update script:
setenv root_loop 'setenv start 24000 && setenv r1 $rootblks16 && while itest $r1 -gt 0; do if itest $r1 -gt 0x100000; then setenv count 0x100000; else setenv count $r1; fi && mmc dev 1 && mmc read $loadaddr $start $count && mmc dev 0 && mmc write $loadaddr $start $count && setexpr start $start + $count && setexpr r1 $r1 - $count; done; setenv r1; setenv start; setenv count'
setenv install_firmware 'echo MBR... && mmc dev 1 && mmc read $loadaddr 0 1 && mmc dev 0 && mmc write $loadaddr 0 1 && echo U-Boot... && mmc dev 1 && mmc read $loadaddr 3F 1FC0 && mmc dev 0 && mmc write $loadaddr 3F 1FC0 && echo U-Boot environment... && mmc dev 1 && mmc read $loadaddr 2000 2000 && mmc dev 0 && mmc write $loadaddr 2000 2000 && echo Firmware Partition... && mmc dev 1 && mmc read $loadaddr 4000 20000 && mmc dev 0 && mmc write $loadaddr 4000 20000 && echo Root FS... && run root_loop'
To calculate the value of rootblks16 devide the size of the image in byte by 512 and convert the result into a hex value.
2070 * 1024 * 1024 = 2170552320
2170552320 / 512 = 4239360
4239360 = 40B000HEX
setenv rootblks16 0x40B000
=> run netboot
