NonPH locking on erase?
I have a nonPH box. I do the norm, reads code/nvram fine. I do modifications to them and go to program code and BDM OFF is in bottom right, and Erase starts.. comes up in output window, but thats where it stops. after 5 minutes still same way. What am I doing wrong?
further info- config is set to nonPH, chip is Intel 28F800C3, USB BDM works fine with CR4 verison board, C105 is lifted. After 'Erase starts...' is on screen for 10 min or so, up to 402000 of code is all FF meaning erase is going TEDIOUSLY slow?
correct range for reprogramming is 406000 aa000 like CR4 boards?

after reset 1
rpc 00000460
A7 00200400
I do reset 1
init
ldram 400000 (load backup)
flshdct code
program
destination 406000 size aa000 with intel chip
Erase starts... thats where it ends. I have tried setram code and it writes but don't actually write, program code 406000 aa000 same thing, program code same thing, program same thing. I have no idea what else to do.
left it go for over 5 hr and no change to the flash.
also tired an init directly before program and no difference.
-reset 1
-R
-init
-ldram 400000
-flshdct code
Found Intel 28F800C3
-init
-program
Erase starts...
where it hangs every time.
software v0.87 dcttest 0.241

this one did have flipped firmware.. didn't really make a difference as it only partially erased the flash and refuses to program.
Im unsure if it would work with the partialy intact flash, it does turn on and show channel numbers. since its deactivated it don't do much else - has a boot dip V5.68 I think.

R7 and RPC looks good to me.
I hope you have removed C105. If it hangs the watchdog is the first thing I will look at.
"setram" CAN NOT used to program flash. It is used to copy NVRAM.
If all the above is cleared, I need to know what flash do you use. See if the line of the flash in flash.def is not right.
Please
1. Copy paste your flash name detected by the USB BDM.
2. Your one line in the flash.def.

-flshdct code
Found Intel 28F800C3
verified it was detected correctly. IRD has 2 28F800 chips.
flash.def file line:
I believe this is correct. Thanks for clearification on setram - makes sense now.
Is it possible that there could be a cold solder joint on one of the IC pins that allow for read, but not for erase? seems weird that it 'partially' works - almost like a hardware issue with the IRD. This IRD is at least 6-7 years old and has been likely on for 90% of that time (I presume)

C105 to be removed.

Yes, C105 is clear of board. I cut the positive side of that, bent it back and slid some electrical tape to prevent it from even inducting much less touching. Identical thing I did to CR4 board, which works perfectly.
I have read through the forums for well into 10 hr now, and no one seemed to have this issue - or posted a thread about it... seems that others do have this issue though as they chimed in here with same occurance.

Whats the hard way to disable the watchdog timer? If C105 isn't working - is there an alternative? I am quite handy with rework - and have almost all needed SMT gear available to me.
also just did a getram code to see how much is erased. the software successfully blanked the flash range 400000 - 480000. The NVRAM has no issues writing to the box on the other hand. did several obsurd modifications to it and wrote and cmpram and they were OK.

Setup VNC or logme in and let me fix it for you. But you must have a good copy of flash and NVRAM and it should not be a big problem for fix it. If you do not have a copy you are more like ly to have a box boot from DIP which gives you "white" diag screen.wiggim wrote:Whats the hard way to disable the watchdog timer?

Hello!!! for all
I have the same problem, 2 boxes with 2 intel flash (Found Intel 28F800C3 ) and another with ST flash does not recognize. the 3 box are dct2000 old board
i can read and have backup for code and nvram.
my steps in intel Flash....
-reset 1
-R
-init
-lram code
-flshdct code
Found Intel 28F800C3
-program code
Erase starts...
I have usbbdm version 0.89 and DCTtest 1,0,0,1
any ideas?
thanks in advance... ingeleo
