Sun May 31 11:43:35 CEST 2020
The ROCK-PI-E is a credit card size SBC based on Rockchip RK3328
Quad-Core ARM Cortex A53.
Net - Dual ethernet port, 1 X Gbe, 1 X 100M
USB - USB 3.0
DC - USB-Type C, 5V 2A
Storage - TF card, eMMC
Just build idbloader.img and u-boot.itb for Rockpi E board and
follow the blow steps to replace the relevant partition.
dd if=idbloader.img of=/dev/sdcard seek=64 conv=notrunc
dd if=u-boot.itb of=/dev/sdcard seek=16384 conv=notrunc
