Connecting as per the wiki’s guidance:
jumper on the last two pins.
USB Male A to Mail A cable to ROCK 3A OTG
Connecting power and otg cable to the computer.
Rock 3a does not enter maskroom mode
Read carefully.
- connect the USB to the computer
- power the board
- remove the jumper after you power the board
then you go check with lsusb.
Hi, I tested it like that too
Maybe you are too fast, or too slow to remove the jumper?
hi, I did the test with 5 seconds and 30 seconds but there was no change
Use a power supply (PD charger) to power the board instead of USB.
hi, same behavior
Do you understand the instructions below?:
- Power on the board
- Take off the yellow hat.
- Check usb device
yes i followed all the intentions but i get the same behavior
other than that, I can’t get adb to work
yeah adb wont work in bootrom
rkdevtool in windows sadly it works better as in linux
the only thing with the jumpers is that you short the spi and emmc device so that bootrom cannot find any device and as long bootrom sees a device it would not enter bootrom mode
so there only 2 things
or wrong otg cable
or it still sees a device
as long rkdevtool dont see a connected device you do something wrong
that is why it is easier in windows as in linux in windows it alarms you when rkdevtool sees a device by sound and confermation you got a device connected .
I’ll try using the serial monitor to see if I have any extra info.
https://wiki.radxa.com/Rock3/dev/serial-console
Can you get into maskrom now? Hardware
This page indicates that I should connect the pin on the left and the middle(The Hdmi interface is facing me), and in my experience, I need to repeat this step many times to enter the maskrom
thanks for replying but i tried with the jumper like that too
The serial only returns me something when the SD card is plugged in

Can someone help me?
Try to do something different:
- flash sd card with latest radxa image,
- compile rkdevtools (recently it has problem that it’s described on rk github, easy fix)
- connect one rock 3A board (with maskroom jumper) with another - it should detect it without any problems
if this fails then replace cables/chargers/jumpers - something is faulty, maybe Your jumper?
Usb-A/Usb-A cable is not that popular, there are some only for charging, but it’s quite easy to find usb-a/usb-c and adapter to usb-a that works.
Few days ago I tested this setup and I’m sure that it works (I tested that on few Rock3A versions.
thanks for answering.
I tried compiling again. I connected the rock 3A with several jumpers and cable I tested it with the usb otg switch but I always have the same behavior both in linux windows and mac.
I can’t figure out what the problem is, try looking at the rock 3A serial as well.
Do you have any tips on how I can debug the problem?
gratitude for answering
