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.
No no, please donât 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 donât provide enough power to perform all needed tasks
Iâve 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 itâs faulty, but that failed to communicate after bootloader with any reason.
Check other ports, as well as different cables and setups. Itâs not thing that is perfectly clear and even some thick cables are just useless. I donât have any âradxa cableâ 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. https://wiki.radxa.com/Rock5/guide/serial-console
I am kind of stuck here
Uart has nothing to do here if You are trying same thing as on top post, also I donât 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 doesnât 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 isnât particularity reliable at 1.5Mbps I couldnât 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.
i used the FT232 initially and then with CH340, both doesnât give any UART.
For me the board doesnât 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 â3) Boot the board to Maskrom modeâ . It took me a few attempts, If you try it under linux, âlsusbâ shows me
Bus 001 Device 024: ID 2207:350b
It puzzled me as I was expecting âFuzhou Rockchip Electronics Companyâ but no description just the usb id 2207:350b indicating the board can be communicated with.
lsusb database may be inclomplete or even empty, donât worry about that,
most important You have good usb id device and label for that is not needed.
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 ?
Check out if its possible to enter maskroom mode so there is some hope for itâŚ
Double check every other thing (mainly ac adapter), disconnect all accessories, chceck out if there is anything on uart.
