Data Access Exception [solved]

[darf]

Recently I've been getting this error message when booting/resetting my SS5,

extensive google searches have not turned up anything useful, hoping someone here may be able to guide me to a solution.

This is what I get on the promt:

Code: Select all

ok set-defaults
Setting NVRAM parameters to default values.
ok reset
Resetting ...
Data Access Exception
Type  help  for more information
ok

Oddly this did not happen last week so its gotta be something new, I also keep getting watchdog errors whcih I believe are kernel traps when I do various things like boot net or emerge --sync etc.

Thanks for any help

Looks like I found the issue, memory in Bank #1 is not beeing detected, which means the memory is not continuous which causes the data exception error. I should have guessed that I had an issue when I saw 96MB RAM instead of 128MB, joke's on me.

Code: Select all

...
Probing Memory Bank #0 32 Megabytes
Probing Memory Bank #1 Nothing there
Probing Memory Bank #2 32 Megabytes
Probing Memory Bank #3 32 Megabytes
...

In case anyone else is having this issue you can generate additional messages with the test command by plugging in to a serial port and setting diag-switch? to true, then do a reset:

Code: Select all

ok show diag-switch?
diag-switch? =        false
setenv diag-switch? true
diag-switch? =        true
ok reset
...
