Kernel 5.2

Install to SD CARD

• Make it executable
  sudo chmod +x flash_sdcard_m64.sh
  sudo chmod +x format_sd_mainline.sh

• Format the SD card or the mmc device
  sudo ./format_sd_mainline.sh /dev/sdX (where X is your device letter)

Usage:
./flash_sdcard_m64.sh (SD CARD: /dev/sdX where X is your sd card letter or /dev/mmcblkY where Y your device number)

• Flash
  sudo ./flash_sdcard_m64.sh /dev/sdX (where X is your device letter)

Install to eMMC
Boot from the SD CARD and find the /dev/mmcblkY where Y is the number (0,1...,3) for the eMMC.

Format and Flash to eMMC (mmcblk2 when boot from SD CARD):

sudo ./format_sd_mainline.sh /dev/mmcblk2
sudo ./flash_sdcard_m64.sh /dev/mmcblk2

You may need to adjust the device number when you boot from eMMC.
Edit the file boot.cmd and change root=/dev/mmcblk0p2 to root=/dev/mmcblk1p2 and recompile the file with:

cd /media/$USER/boot/
sudo mkimage -C none -A arm -T script -d boot.cmd boot.scr
sync

and reboot.
