I been reading the guide for a few days now trying to grasp how this all works but still finding it i hard for it to l sink in. I'm trying to fix an atmega card because i think its the easiest one to do as you don' t have to play around with the keyroll.

having looked at the 3.7 log am i right in thinking that to fix the timing issue cmd $00 is where the problem lies and is the only piece of code that need to change, Forgive me if i'm talking bollocks.

Is there a guide somewhere that shows you how to edit the asm code and how to use AVR studio 4.

3.7 log below.

No, Im just us stuck as you if not more, ive read up on how the code works on avr, Then i had probs running avr, so ive open ida, But nothing looks the same

Ive been reading about old keyrolls in the hope i can answer nozzers questions on prev page

As i keep hearing we need to understand key roll system first.?

Im a bit stuck is wrll m8, trying to figure out how to yse aver studio but cant get my head around it, is there a easier option such as using note pad to make changes to the flash.

TBC · 13th November 2009, 14:46

hi chaps !

I just popped over to look at the question being framed by nozzer and see if maybe there was a simple reason why it was causing confusion.

I think you might be better off forgetting keyrolls ect for a time, i think the way this is being put across is from the aspect of starting from scratch yet building a conoceptual understanding based on pulling the code apart.

first off one of the thing that make serial comms different from parallel ect is the way data is transmitted. 1 single bit at a time rather than bytes or words.
If things are sent 1 bit at a time as they are in iso comms and rs232 then each bit is received loaded then the next bit is received and loaded until you get a full word - then you can store the word to ram. and get the next.

There are 2 forms of serial comms that can be utilised. Asychronous and synchronous, 1 meaning use of a common clock and one meaning on the fly. The later often utilizes start and stop bits.

I realise this doesn't give you much to go on BUT it does actually help point your googling i think. Without knowing how data is exchanged on a basic level in a serial form you wouldn't even be able to start looking at a keyroll ect becuase you couldn't get the card firmware to understand the host device and visa versa. It's very much the same in glitchers.

here's a for example of how stuff can mess up;

a while ago i was trying to make a flash to run at 18mhz, the comms are serial and so they have to be timed correctly. After a while pulling the original code apart i thought i had it all worked out. I was wrong lol, what i was getting back was supposed to be an ATR but it didn't make any sense. After studying it for ten minutes i realised all the bits were shifted left so the bytes were all wrong. Of course i'd spent that much time on it by then i was able to see the flaw and fix it straight away.

So get googling serial comms protocols and have a look at iso smartcard protocols as well, should give you a good step in the right direction. Especially since there is source code for the funcards knocking about over the net.

Good to learn so i thought i should

thanks alot

i have been reading, reading then reading over it again as not somethink you can just browse over and expect to do sadly.
then MW2 came out so this took a bit of a back burner with me.

from what i have read so far, I think it's this part of the source code that needs to be changed

Send_Reply:
mov LEN, r18 ; LEN
mov PCB, r16 ; PCB

ldi r25, 128
rcall Delay

mov r16, NAD
sts rNAD, r16
mov r16, LEN
sts rLEN, r16
clr r18

rjmp Err_Respond

more like the method needs to be changed so that the rcall happens sooner than its currently doing. If i was on 3.7 would be easier to mess with test etc, as im still on 3.6.

im messing with this part at the moment

Send_Reply:
mov LEN, r18 ; LEN
mov PCB, r16 ; PCB

ldi r25, 8
rcall Delay

dont you have a box you can bang on 3.7...? Or anything you need testing i dont mind helping,

windy1603 · 15th November 2009, 13:59

I am on 3.6 i did all my testing using XNCS as you can send commands etc to card to test. I found just doing a reset card command would show all of the errors in the comms tab.

Just remember guys the logs only give an symptoms of what is wrong. You can go down the wrong route like i did (I rewrote the whole recieve data routine as i thought that where the problem was based on the logs and it made no difference) the logs show what is sent to the card (not what the card recieved)

If we assume that the command response part of the code works OK (as it did in the past). It can only be the card is getting the wrong data and sending an invalid response or no response based on the faulty data. What would make the card recieve the wrong data ?

I just popped over to look at the question being framed by nozzer and see if maybe there was a simple reason why it was causing confusion. I think you might be better off forgetting keyrolls ect for a time, i think the way this is being put across is from the aspect of starting from scratch yet building a conoceptual understanding based on pulling the code apart. first off one of the thing that make serial comms different from parallel ect is the way data is transmitted. 1 single bit at a time rather than bytes or words. If things are sent 1 bit at a time as they are in iso comms and rs232 then each bit is received loaded then the next bit is received and loaded until you get a full word - then you can store the word to ram. and get the next. There are 2 forms of serial comms that can be utilised. Asychronous and synchronous, 1 meaning use of a common clock and one meaning on the fly. The later often utilizes start and stop bits. I realise this doesn't give you much to go on BUT it does actually help point your googling i think. Without knowing how data is exchanged on a basic level in a serial form you wouldn't even be able to start looking at a keyroll ect becuase you couldn't get the card firmware to understand the host device and visa versa. It's very much the same in glitchers. here's a for example of how stuff can mess up; a while ago i was trying to make a flash to run at 18mhz, the comms are serial and so they have to be timed correctly. After a while pulling the original code apart i thought i had it all worked out. I was wrong lol, what i was getting back was supposed to be an ATR but it didn't make any sense. After studying it for ten minutes i realised all the bits were shifted left so the bytes were all wrong. Of course i'd spent that much time on it by then i was able to see the flaw and fix it straight away. So get googling serial comms protocols and have a look at iso smartcard protocols as well, should give you a good step in the right direction. Especially since there is source code for the funcards knocking about over the net.

If i was on 3.7 would be easier to mess with test etc, as im still on 3.6. im messing with this part at the moment Send_Reply: mov LEN, r18 ; LEN mov PCB, r16 ; PCB ldi r25, 8 rcall Delay __________________ [SIGPIC][/SIGPIC] I live to GiveI LIVE TO GIVE DIE HARD SHEFF WED FAN & ARCADE KING!!!

I am on 3.6 i did all my testing using XNCS as you can send commands etc to card to test. I found just doing a reset card command would show all of the errors in the comms tab. Just remember guys the logs only give an symptoms of what is wrong. You can go down the wrong route like i did (I rewrote the whole recieve data routine as i thought that where the problem was based on the logs and it made no difference) the logs show what is sent to the card (not what the card recieved) If we assume that the command response part of the code works OK (as it did in the past). It can only be the card is getting the wrong data and sending an invalid response or no response based on the faulty data. What would make the card recieve the wrong data ? __________________ You only need two things to fix anything. WD40 and Duct Tape.
