Ok I found the solution! Based on provided scripts from FriendlyARM (sd-fuse_rk3399), I made this script to flash parameters, kernel and dtb files only into the first raw partition.
I copied usefull files next to my script :
- kernel.img (kernel binary)
- resource.img (dtb, logo, etc)
- param4sd.txt (from sd-fuse_rk3399 repo)
- parameter.txt (from sd-fuse_rk3399 repo)
- partmap.txt (from sd-fuse_rk3399 repo)
- sd_update (from sd-fuse_rk3399 repo)
Code: Select all
#!/bin/bash
# flash=mmc,1:kern:raw:0x2000000,0x2000000:kernel.img;
# flash=mmc,1:boot:raw:0x4000000,0x2000000:boot.img;
