I have a Fuel that's being a pain. After initially giving L2 cache issues, which was mostly likely down to
the system having a 500 CPU when it should have had a 600, it now refuses to power on from the front
power switch and instead the L1 gives this message if one tries with "pwr up":

Code:
ERROR:SCAN:scan error - unable to reset scan hardware


Any ideas anyone? Google gave squat.

Meanwhile, a different Fuel went fubar in the middle of doing a PROM flash to change the settings so
that it would be correct for a 500 CPU module (was a 600). Maybe 10 secs into the flash, the system just
suddenly began a normal powerdown sequence, as if one had used the shutdown command. Now all I
get after power-on is a solid red light. Is the PROM hosed? Where is it anyway? A removable chip?

Not having the best of days...

Ian.

In theory you should be able to remove the prom chip and slot/solder a new one in, as they are usually separate READ ONLY chips.

There is a series of L3 tools related to SN1 scan/JTAG functions. I haven't had an opportunity to do much more than take a brief look at them, <so I don't know if they'll be helpful in your situation>, but it might be worth an in depth look <included are a "scan_Asterix_01" script and a tool to decode smdk error logs>.

And what magical chip would that be? It's not the Dallas chip, or the yellow one, or the 8-pin chip next to the fan header.

Hmm, for the time/effort involved, I might be better off just junking the mbds. Ah well. Thanks!! 8)

Well that would depend on the kind of PROM I suppose. I am just going off what I know here, in theory it should work.

What I meant was, as far as I can tell there is no chip of this kind which can be removed in that way. None that I can see anyway.

Having just last night reset a Fuel for use with a 600 (was an 800 before), the PROM that gets flashed is the 'Bedrock PROM', whatever that is. My first thought is that it is internal to the Bedrock ASIC, but would have to investigate further.

Hi everyone,

and after 2 months of waiting, I finally got my Fuel, and well, it doesn't power up :(

Any ideas what might the issue be ?

If my logic is right I would bet on the mainboard not receiving required voltages (some at all) from the PSU - could that be the case ?

I already vacuumed the dust from inside and reseated connectors - especially power supply with no change in behavior.

*edit, I tried to play with L1 a bit, and all I got is that all states are Enabled with PIMM 1.5 Faulty...

I think PIMM means the CPU...

It does, but I'm trying to figure out whether this could be PSU , NODE board or the PIMM module.
Afaik, PSU doesn't supply 1.5V, and maybe not even 3.3 so there should be some power regulator - for the 1.5V it could be on the PIMM board.

"Finally got" as in it arrived via some parcel service? Might be possible that your Fuel took a few hard knocks while in transit and the processor module or some other essential component isn't making sufficient contact allow the L1 controller to scan the bar coded serial number (if you're right and the 1.5V vrm is on the processor module, it might also explain the faulty 1.5V message)?

What's "serial all" look like?

Well, the hard disk is working - if it had taken a few knocks I would expect it to rather give up and die :)
But it' entirely possible, I've already taken the PIMM out, used some air spray and firmly reconnected it.

The serial numbers are actually readable:

I got it from Hamei - it shipped via China Post -> Japan Post (SAL - economy), I wouldn't be surprised if the first carrier wasn't very careful with it..

One more thing I found out - there was PCI blank flying around inside - I think it got detached somehow during transport.
When I found it - it was near the PIMM on top of the front fan cover, it wasn't really touching anything while powered on, so a short is unlikely. but who knows.

What's in the L1 log, and what does "pimm" return? While you're at it, you might as well describe what the Lightbar is doing when you attempt to start up the system.
