Customboard with RK3566 flashed with OrangePi3B Armbian minnimal image, no more MaskMode in RKDevTool

Norbert Oravetz · February 14

Hi Gents,

I would like to ask for your help or tips and tricks in the following problem...

Basically to keep the long story short, I have a custom board with RK3566 and 2 GB of RAM, 32 GB Samsung emmc on it ... basically if you are familliar it is a Linxdot Helium miner which has some problems with the onboard Lora module.

I had tried to flash using RKDevTool a few Debian version that I found for Rk3566 but not all of them worked properly. All the time I was able to reflash it by using RKDevTool by pressing the button while I powered up the board but after flashing the Armbian minnimal for Orange Pi3B I can't use the RKDevTool anymore, it is simply not seeing the board anymore (No device found). I have an UART 3.5mm Jack type port, I had a homemade cable so I was able to create the user at the first boot, I am able to log in, but there is no HDMI, the ethernet port is no recognized, WiFi also not recognized, I am plug in a USB Flash stick and I am not seeing it in the lsblk command output, so basically I have now a very basic board. (I know, I am stupid, but I was thinking that I can't damage it because the RKDevTool was working fine under all previous circumstances).

My question would be, if there is any possibility somehow to restore the functionality to be able to boot it in MaskMode for the RKDevTool or any other solution to make at least the Ethernet and USB ports to work?

There are no other button, just 2, one reset and one user button on it. All the time I had to keep pressed the user button in order to be detected by the RK tool. There are no jumpers on the board (at least I can't find them) which I can short to stop the emmc from booting or similar things

Many thanks in advance !
