Cisco 871 Data Access Exception


I just managed to get my hands on a CISCO 871 router but when I turn it on I have some errors:

*** Data Access Exception ***

PC = 0xfff3026c, Vector = 0x300, SP = 0x8000498c

The first time I powered on the router it booted, then I turn it off and since then I have this errors every time it boots up. If somewone can give some info about the errors so I can try to remediate.


I tried to replace the IOS from rommon thinking is corupted but I get this:

Warning: Trying to free already-freed memory!!!

Warning: Trying to free already-freed memory!!!

flashfs: out of memory.

Failed to register flash with file system

*** Machine Check Exception ***

PC = 0xfff210f8, Vector = 0x200, SP = 0x80004bcc

the same happens when I try to format the flash.

Cisco 871 Data Access Exception

I managed to fix the problem. I opened the router, took the flash and the memory out of their slots then I put them back; it worked, now my router is booting and working.

Thanks anyway for your help
