Re: [Elecraft] K3 appears to be bricked

[Ron D'Eau Claire]

Did you have the KIO3B board installed during the repair so you have an 8P8C
connector (sometimes called an RJ-45) on the rear panel? If so, you MUST use
the 8P8C and an RS232 port on the computer to reinstall following a failed
load.

On the front of the KIO3B main board, near the speaker cable connector, is a
toggle switch. Remove the K3 top cover and place the USB <-> USB/RS232
switch in the USB position. You should have received a suitable interface
cable with the upgrade but you'll need an RS232 adaptor if you don't have an
RS232 port your computer. 

Be sure to return the switch to the USB position after completing the
firmware upload.

Thanks for the suggestions so far - tried each several times but the K3 is

All you have to do is turn everything off including the computer. To turn
off the the K-3 you have to remove the power connection. Next, turn on the
computer. After the computer boots up, connect the power to the K-3 and turn
it on. You will see the same MCU LD message and blinking transmit light, but
the computer utility program should be able to find the K-3 and reload the
firmware.

Re: [Elecraft] K3 appears to be bricked

[Mike Murray]

Once again, thanks to everyone on the list for input.  I was finally
successful in getting everything reloaded only after disconnecting
everything but the serial cable to the PC.  Thanks to Don and Bill for
pointing that step out as a solution.  Thanks also to Dick for pointing out
the help files in the Utility - just never thought to look there as well,
but will if it ever happens again.

There is a fairly detailed procedure in K3 Utility Help, Troubleshooting,

I was in the process of updating my K3's firmware this morning when
something apparently burped leaving the K3 bricked.  The radio is wired
directly to a power supply  which also feeds a RigRunner for other stuff.
At the time I was also using a small 12V air compressor on the RigRunner.
I don't think it was involved, but can't say for sure.

The TX light is flashing, the display shows "MCU LD" and power button won't
power it down.  I've tried forcing a firmware download several times,
explicitly following the instructions in the K3 manual without success.
The K3 Utility program can't find the rig on the prior COM port being used,
nor on any other available COM port, so I suspect that's a major clue.
True COM ports are not available on the PC so I'm using a StarTech 4 port
USB converter that utilizes the FTDI chips.

Anyone have any ideas I can try???

Re: [Elecraft] K3 appears to be bricked

[James Walker]

Do you have a P-3? If so, you might need to reconnect the RS232 directly to the 
K-3 rather than the P-3 before starting the process.

Re: [Elecraft] K3 appears to be bricked

[Don Wilhelm]

Mike,

Remove the K3 power cord and wait at least 2 minutes.
While waiting, reboot the computer and after it comes up, power on the K3.
Check to see if K3 Utility can find the K3.
Try the Force Firmware Download again.
If that still does not work, disconnect everything except the RS-232 
cable from the K3 and try the sequence again.

Re: [Elecraft] K3 appears to be bricked

[James Walker]

I have the same problem with my K-3 from time to time. It’s a major 
inconvenience but it’s not fatal. I’ve tried a couple of times to get help from 
this forum but no one seems to have a good answer. My best theory is that there 
is a defect with the firmware chip. It’s not a widespread defect, so my theory 
goes, since most K-3 users don’t suffer from the problem. I’m sure Elecraft 
would replace the chip but I can’t be sure that’s actually the problem. So I 
just live with it.

All you have to do is turn everything off including the computer. To turn off 
the the K-3 you have to remove the power connection. Next, turn on the 
computer. After the computer boots up, connect the power to the K-3 and turn it 
on. You will see the same MCU LD message and blinking transmit light, but the 
computer utility program should be able to find the K-3 and reload the 
firmware. 

Lastly, and sadly, if my experience is any guide, you’ll have the problem again 
from time to time.

Have you removed power, waited 2 minutes, then restored power?
