I`m working on SOM-RK3399 devkit for prototyping. And I'm considering to use eflasher for cloning eMMc image of dev-board to another board's one.
So, I try to burn eflasher image ( rk3399-eflasher-lubuntu-desktop-xenial-4.4-armhf-20200916.img ) to 64GB class 10 micro sdxc card.
I used dd command on lubuntu-desktop that Friendly-elec provided, and dd command succeed without error. Then, I insert sd card to dev-board and turn power switch on. But, display shows nothing, and CPU board looks like not working. I checked config of router that is connected to dev-board, then I'm sure that DHCP assign IP address to board. But, tring to connect with ssh fails. says connection timeout.
Is there something that I missed ?
I used following command to burn eflasher image to ssd
I also checked md5 of eflasher image and it is not broken.
