I need someone with a flash problem to try this. You must have a 301.013 with a single 4mb tsop and the am29lv320dt tsop chip. I would do it myself but I already committed to another receiver. I want to know so when I mess this one up I can recover.

1. go into jkeys.
2. select your receiver manually
3. select flash programming.
4. get into program mode.
5. click the check emi button.
set them as follows:
bank 0: 0670
bank 1: A7D1
bank 2: 46D1
bank 3: 66D1
update all banks.
If you already had these numbers than you have a different problem.
(do not proceed).
6. full erase.
7. turn on vid mod
8. attempt to write flash.

Please post your results.

If you have a different receiver, get the proper numbers from someone else or another working receiver.

No luck. This receiver has slowly fallen off to where green light doesn't even come on anymore and, of course, can't do a damn thing with jkeys. Not sure why? The other 5 I did(vidmod) worked just fine.

Does it at least recognize the device id under jtag info? you need to get at least that far before you can do any programming.

I tried it with mine.

It recognizies the CPU on the IRD dectection page.
IRD model number is undected, but I expect this because I belive the flash to be erased.

The flash mfg/model still comes up as 0xffffffff/0xffffffff on the flash programing page. At one point I even went and edited the jkeys config file so that an STi W29M320DT used ffffffff/ffffffff as it's reported codes so I could at least try to program it. I now realize this was foolish, because if it can't even read the mfg/model id then the processor trap probably isn't in effect and you have about zer0 chance of getting acceszs to the chip.


I am confused as to why we need the trap at all. If we have the correct pin grounded haven't we effectively halted the CPU clock?

aunther - you are having the same problem I had. However, my receiver has the am29lv320dt chip and the settings I gave are for that chip only. I don't think they are the same settings, but I'm not sure. The settings affect how the cpu accesses memory. I was hoping that these settings would allow access to the flash after a wipe. Maybe this is a lost cause. Good luck.

We'll see. I found a copy of the of STi5518 specs in the files area. It's got a great section on the DCU. I have a lot more information now, and some things I want to try.

No, it doesn't. If I could get that far, then I don't think I would have any trouble erasing and reflashing.
