I am getting “Config Error:Failed to update IO Firmware” after flashing Ardupilot V4.2.3 via mission planner and above on my pixhawk cube orange+.I tried booting using safety button,but it did not help.
I am using Here 3+ GPS,all params other than NTF_LED_TYPES have been saved successfully but when I write this param gives me the error :"Set NTF_LED_TYPES Failed.
The GPS is still lighting all the LEDs(purple,yellow,green)
Hello @Uditi , welcome to the community,
Please update to ArduCopter 4.4.3 and retest.
Thanks for replying !
I started with ardupilot 4.4.3 but it gave the same error so went back to previous versions
By now you found that this is not a regression and as such not fixable by using an outdated software version.
That I did, I was just trying out different things, just to see if anything would work because I couldn’t get any solution anywhere.
I have same problem with OrangePlus+ after did more 10 good flight, after day, drone returned that msg and nothing is doing more !
I update new firmware, return to my origin firmware, nothing. I think that is internal error !
hello, any solution here ? i’m having the same problem
Try QGroundControl and flash Arducopter latest Stable. Not this 4.2 version you posted in.
i just did it, no hope, by the way now it can’t connect to mission planner, it seams it’s not booting correctly.
Press and hold the safety switch while rebooting
did it so many times, then power off/on again, no hope.
my problem now is that the cude doesn’t want to connect !
if i install PX4, it runs great, (but without main outputs)
i can’t connect to mission planner !

hi, unfortunately no, i bought another one, didnt tested yet, lets see.
i tried everything possible to repair the old cube (of course without opening it) no way.
i had a call with one of cubepilot managers, he recommend sending the device to the seller.
i contacted aliexpress guy, no response.
@paulfa Hello. How is your new orange plus working out? I have the same problems in 2 cubeOrangePlus. Could this be a fault in the new cube orange series? Seems that everyone has the same problem, nothing out of the ordinary then suddanly it gives this error? Seems fishy to me. Never had this problem before with my black cube. Has been working great for 3 years now.
my new orange plus is working fine !! LOL
it worked fine out of the box, i ordered it from 3dxr.
whith the old one, i noticed some strange behaviours, such as : problem with connection, failed to boot, have no idea why.
i think its a software/boot loader issue, i will repair it one day.
i heard that intalling QGC will affect the IO firmware, not sure.
regards.
Good to hear!
I am myself wondering what to do with the two that I have. I had the same problem as you, strange behaviour, connection problems, then failed to boot (IO error).
If it is a software related error, isnt there a easy fix that can resolve it?
I have always used QGC (have a herelink that is compatible with it), and that error came when using it.
I will let you know if I find out something, and hopefully you can tell me if you find a easy fix for it 
Good luck with your project!
I had the same issue with my Holybro Pixhawk 6c mini. I was able to upload PX4 but not the last version of ardupilot (4.5.6).
I had the same message : "Config error: failed to update IO firmware”
Note: only the FMU ACT and FMU B/E leds were off.
I removed the SD card while the board was off, then I turned it on. The FMU B/E LED started to blink. I turned off the board, inserted the SD card again, turned it on and from that moment the error disappeared.
