Barracuda Networks F80 Repair (Atom c2000 bug)

(1/3) > >>

hy,
I have heard about repairing a synology NAS with the same cpu as my networking appliance(intel atom c2358)
https://www.eevblog.com/2020/03/10/eevblog-1288-synology-nas-dumpster-find-repair/
The cpu has the same errors, I fixed some appliances by completly change the cpu (BGA soldering by a company)
But this was to expensive.
I wonder if it would be possible to do the same as on the synology nas?!
My appliance is a Barracuda Networks NG Firewall F80.
It is manufactured by Lanner as far as I know.  The mainboard is from Microstar Internation - MSI.
I made some pictuers of the board.
I dont have any description of the appliance.
Is anyone able to help me get this done?
This is my first post in EEVblog, repairing stuff is a good thing instead of trash the usefull stuff.

you skipped the diagnose part, verifying if the processor is not soldered correctly, you didn't mentioned what's not working, does it boot etc...
try starting it pressing the cpu if it doesn't boot, see if it displays at least first page, or give us details about the failure

It can be repaired by simply connecting a pull-up resistor between LPC_CLKOUT0 and/or LPC_CLKOUT1 and +3.3V power rail. The same as an official fix for Synology NAS, no CPU replacement needed. The issue is if LPC is exposed on particular PCB and if you can find it.
