the best thing to think about with this problem is:
why did the cards work ok on the 3.6 aqnd not the 3.7?
well the 3.6 software sent the card some info and waited for a responce, lets say (and this is not the real time) 40 cycles, if it did not get a responce from the card for some reason it would wait just a bit longer and then pop! the responce that the box was waiting for came..
but in the 3.7 software the box sends the card some info (same as 3.6) and waits for a responce lets just say 40 cycles again, and when it did not get the responce the box does a resend of the information again and then waits, it does not do what the 3.6 did and wait that bit longer, so the 3.7 would keep resending the command to the card and not getting the responce so in the end would just stop..(this is the easyest way i can put it)

so really you have to change the flash to make sure it responds to the box in the correct time. there are more than 1 ways to do this. some have done the ICP way, which i think is the hardest way but problery the best and then there are other ways..

also if you are doing it for the fun you are going to have to do the new keyroll as well as its not set up in prune.asm or grape.asm but its in the redneck.asm but thats for atmega cards, but can be used to do the prune/grape.asm.
i would say fix the fun or atmega first then try the keyroll 8 for the fun card after, if you do the atmega then the keyroll is already done so you dont have to do it!

you are going to need to learn some info on AVR source code, to get a better understanding but that is good as you have a project to do while reading so you can put what you read into practice.

here are some links i have collected see if they will help but google is good!

Code:

http://www.atmel.com/dyn/resources/prod_documents/doc2505.pdf

Code:

http://www.avrbeginners.net/

that is but a few thats out there i am sure people have others!
also AVR studio is a good thing to download and its free, then you can compile your own project with the files from the .asm, and look and make your flash with it.

hope that helps a bit

i noticed that on the 3.7 update file, this is repeated

21 C1 01 ; FE 1F
12 E1 01 ; FE 0C

21 00 08 ; A0 CA 00 00 02 C0 00 06 87
12 00 08 ; B0 04 08 03 00 00 90 00 35

21 C1 01 ; FE 1F
12 E1 01 ; FE 0C

does it a few times, and from what i have read it's asking for info which makes sense as it does it a few times before failing as the information doesn't get sent. in the 3.6 it did send, so worked.
So im guessing if you had both files you could change them a bit and add the code that worked in 3.6 and included it within 3.7.
As i say im just skinning over stuff at the moment

there is not 2 files thow, its just the 1 flash file, the same 1 as 3.6 it just has to be modded for the 3.7. this is because the 3.6 has a timing issue that was there before 3.7 was out but did not matter. they have just tighted up the timing thats all..

you will have to open the .asm in wordpad or notepad and look at it in there, look for were you could change things to get the correct or as near as timing right. have a read of some AVR source info also the stunt guys faq so you know what the timings should be and were, and also what they are doing. you will need to get some basic knoledge of the code so u know what your changing/looking at. but as you have the .asm open you can look between the info and the .asm so u can see what is what, this does help alot.

thanks guys some good info

yeah meant sending it back to the box lol
also downloaded AVR studio just looking over the files etc and having a read of the guides.
More or less worked out the the timing has to be the same as the box otherwise it will blackout.

still getting my brain into gear for it all tho, but the guides and files have been a great help.
I think once you get the correct timing on the file, then it's just changing the code to update it.
But it's try and error for me at the moment.

cg010169 · 6th November 2009, 15:17

I also think the timing has to be changed from to either 15 or 20. Might be completely wrong, might have read to much info and getting mixed up lol

cg010169 · 6th November 2009, 15:21

now think it's 32 cycles lol

The problem is really more to do with synchronisation of the incoming bitstream rather than command response times. Generally, the commands themselves respond well within the required timeframes (in most cases, the response is actually better than a real Mosc card due to the funcard doing far less checking and being a more efficient processor). The only real area where command timing is an issue is EMM processing where the funcard takes approx 8 secs to decrypt an Emm as opposed to 500mS for a Mosc card. The only reason this works is because the Emm processing is done in the background and the stb is generous enough to occasionally poll to see if the result is ready.

If the incoming bitstream isn't properly synched, then the card itself doesn't see a valid command..........

The bit timing has always been the Iso-defined standard bit time requested by the Nagra card. Thats 32 IsoClk cycles per bit !

If you work that out then, for the 3.68Mhz Xtal used in most phoenix devices you'll get -

( 1/(3680000) ) * 32 for a bit time of 8.6956 uS

or a baud rate of -

1 / 8.6956 uS = 115,000 baud (115Kbaud).

You could simplify the above and just do (3680000 / 32) if your not interested in the actual bit times.

This is why programs like NagraEdit connect to the card at 115Kbaud !!!

cg010169 · 6th November 2009, 15:45

well my head hurts now, worked more in the last 2 hours than it has in last month, but all good lol

Code:

eq_Reset:	ldi	r18, $40
		sts	rPCB, r18	; PCB = $40 

		ori	r16, 0x20	
		mov	r18, LEN	
		rjmp	Send_Reply

will have a better look through it later, but i think this is what needs changing. not 100% I might add lol

Pretty warm but no cigar for you yet

Rather than trying to fix the problem straight off, why not try to understand how the system works first. Start by explaining exactly how serial data is captured by the funcard. Once you understand that then I think you'll be in a much better position to fix the problem.

Thanks for clearing that up madBrummie and Nozzer.

What are the 3 files for? My guess is:

Prune/Grape for Fun
Redneck for Atmega
Chaos for ?

wasn't the chaos file for 2110 issues ?
