Rock5B solid green LED and doesnt boot

#1

i bought a rock5b recently and was working all well with microSD card. All of a sudden the display went off and the LED shows solid green colour after that. Tried with a different MicroSD card, also tried following the advanced method as mentioned https://wiki.radxa.com/Rock5/install/spi to see if the device can be recovered, but gives below error.

I tried reading the GPIO pins using the Serial Port and via putty, but they dont give any readings.
Any pointers or suggestions to recover the board.

Its hardly one week i have bought the board :frowning:…

Looks like your board is faulty…

#3

No no, please don’t write over and over again that boards are faulty if something went wrong,
There can be many reasons that command above fails, probably just bad quality cable was used. Also there are some problems with drivers and rkdevtools versions, sometimes usb port just don’t provide enough power to perform all needed tasks

I’ve got best result with usb-c - usb-c cable that came with docking station, some ports are marked with some thunder or just amperage so they provide more power. Try several things. Test device fails does not mean that it’s faulty, but that failed to communicate after bootloader with any reason.

Yup, it’s true that it might be the cable - I assumed @sandeep checked this

#5

yes, i used the radxa provided type c->c cable which came with the PD30 to perform this.
Still the same results.

#6

Did you check the wattage of your power supply? A lot of people have had issues with ones that don’t supply enough power.

#7

Check other ports, as well as different cables and setups. It’s not thing that is perfectly clear and even some thick cables are just useless. I don’t have any “radxa cable” but You need to check few things to find suitable. If that fails check different computer and connecting via hub/docking station.

thanks for the suggestions @dominik.
I tried with several cables and different PCs, but the same issue.
I also checked with a CH340 Serial reader to see if the GPIO pins give out any info, that is also not giving any readings.

I am kind of stuck here :frowning:

Uart has nothing to do here if You are trying same thing as on top post, also I don’t know if there will be anything.
What version of rkdevtools are You using?
Is system booting from sd card?

Its not booting or the board is not responding by any means and i got the reply from Radxa Support about possible faulty board and request for RMA.
But AllNet Customer care doesn’t respond. All emails go unanswered. @NBA
I bought the board with very high expectations and now i regret that buying decision with board dying in few days.

I suggest trying to see if you get UART output on boot as this should confirm that your board is alive. However CH340 isn’t particularity reliable at 1.5Mbps I couldn’t get any of the ones I had to work at that speed with the Rock5b. I reverted to a FT232 although CP2104 should work, see this link about CH340 issues at 1.5Mbps.

#12

i used the FT232 initially and then with CH340, both doesn’t give any UART.
For me the board doesn’t respond to anything other than showing the solid green light ON all time.

Then the next option is to see if Maskrom mode can be enabled for the SOC to be alive, as per “3) Boot the board to Maskrom mode” . It took me a few attempts, If you try it under linux, ‘lsusb’ shows me

Bus 001 Device 024: ID 2207:350b

It puzzled me as I was expecting “Fuzhou Rockchip Electronics Company” but no description just the usb id 2207:350b indicating the board can be communicated with.

#14

lsusb database may be inclomplete or even empty, don’t worry about that,
most important You have good usb id device and label for that is not needed.

#15

Hi, I have got the same problem, after few hours of work (Rock5B with radiator) , the board stoped working and the green LED is always on,
No way to restart the board, where is the problem ?

#16

Check out if its possible to enter maskroom mode so there is some hope for it…
Double check every other thing (mainly ac adapter), disconnect all accessories, chceck out if there is anything on uart.
