SG135 C2000 BUG

Hello, I recently bought a used SG135 rev.1 which has AVR54 bug (I found out about this bug after I buy it).

For others vendors I found a possible fix, but not for Sophos.

There are two (as far as I know) fixes:

1. Replace a atom c2xxx with C0 revision

2. external pull-up resistor (18.2k to 10k), from LPC_CLKOUT0 or LPC_CLKOUT1, tied to 3.3V

Did someone tried to fix this bug? (I use home license, so I don't have any agreement with Sophos).

 

Best regards,

  Robert

  • Ahoj Robert and welcome to the UTM Community!

    I haven't been inside an SG 135, are you telling us that the Atom processor cannot be replaced?

    Cheers - Bob

  • Hello BAlfons, I didn't opened yet, but generally they are soldered to mainboard, so replacement is very, very hard.

    Best regards,
