Congratulations!
How would it be formatted in the file? All three memory regions or just the data? Binary or ascii? Do you hope to reprogram from the same file?
My preference is binary so one may view it later with hexviewer. If the dump is full card. As we always may read. Then all three memory regions please. Thank you! I owe you some coffee
bus_pirate5_rev10-SLE4442-filedump.zip (173.4 KB)
I didnāt test it. It has no help. I reused the dump command, add a -f filename.bin flag. Format is
MEM: 256 bytes
SECMEM: 4 bytes
PROTMEM: 4 bytes
Iām pushing to a new branch if you need to trouble shoot. its in /commands/2wire/sle4442.c line 313-ish.
Iāll flesh it out when I have a chance.

Iāve got your SLE4442 board. Itās not finding any cards. Just to make sure, what do I need to set up on the BP to test things? I enter 2-wire mode and then try sle4442 init and [0x30 0 0] r:256
Are the switches on or off? Power? What voltage?
Iāve tried both the old SIM adapter and the full card slot. I buzzed the connections and I think they are good.
Any debug tips.
I have a few SIM cards lying aroundā¦ 
p.s. The LEDās never light up. I oriented the arrows in the direction you said. My meter in diode test mode lights them up.
Looking good!
The switches should be set towards the Bus Pirate for normal use.
be sure to enable power with W and usually also a pullup resistor with P.
For a SIM card:
- Use HLFDPLXUART mode (whatever itās called, its an unfortunate abbreviation)
- set to 9600buad, Even parity, 2 stop bits
- W 3.3; P for power and pullups
- G 1 - to generate a clock frequency on IO1/clock
- set to 3.5712MHz, 50%
- type
{to open the uart with live view a 2; @ 2lower and raise IO2/RST- The ART should come out. Usually starting with 3B
- Decoder
For SLE4442 (big chip card, six pins, usually used in hotel room keys):
- Use 2WIRE mode
- speed 20-50khz
- W 3.3; P for power and pullups
- L for least significant bit mode.
} D { ^ } r:4this should fetch the ATR- 0xa2 0x13 0x10 0x91 should be the ATR. If it starts with 0x45 check that you set LSB mode with
Lcommand. - also check out sle4442 -h

Your board might need some flux cleaningš
I just tested that firmware. I managed to dump one card that had some data on it.
2WIRE> sle4442 dump -f card.bin
--SLE44xx decoder--
ATR: 0xa2 0x13 0x10 0x91

Dumping to card.bin...

2WIRE> ls

But empty card gave me this:

Then I did # restart and it worked two times in a row on the same card.

When is Error: invalid path triggered?
EDIT: I see it now. The error is triggered when i used hypen (-) in the filename. Then one need to reset BP5 to be able to dump afterwords.
And after reset and using filename without hypen it works again.
EDIT2: Nope I was wrong its not hypen its filename longer than 8 chars.
Yup, that is it. It shouldnāt hang though. Iāll look into that. Long File Names are not supported, so everything needs to be old 8.3 dos format.

Owww please dont look here why it hangs it doesnt hang i just didnt post the full outputš It throws an error but hangs not.

So the dump to file works but I think it should also be able to dump to screen. Maybe if -f is added then dump to file. And if not then dump to screen.
Yeah, I need to add a new verb (dump/read?) and help and options.
Also write from -f would be usefulš
I never would have come up with this sequence.
Iām having trouble with this step.
When I type
HDPLXUART> G
Generate frequency
Choose available pin:
2. IO2
3. IO3
4. IO4
5. IO5
6. IO6
7. IO7
x. Exit
I cannot choose IO1
I also get this response when I input āG 1ā
Is this on your rev8 board?
Bus Pirate 5 REV10
Firmware main branch (2024-04-13T13:41:55Z)
Iām updating the firmware to the latest as we speak. Aha! Todayās version doesn;t have this issue. Continuingā¦
I used some iso alcohol this time. It looks better now. Thanks.
Sorry for being confused, but I tried your syntax and had problems.
2WIRE> L
Bitorder: LSB 0b00000001
2WIRE> a.2 D A.2 ^ a.2 r:4
Invalid command: a.2. Type ? for help.
2WIRE> a 2 ; D ; A 2 ^ a 2; r:4
Error: IO2 is in use by RST
Invalid command: D. Type ? for help.
2WIRE> a 2
Error: IO2 is in use by RST
WIRE> > a.2 D A.2 ^ a.2 r:4
Error: at position 3 IO2 is already in use
Syntax compile error
Sorry! My fault, I copied and pasted from above, and I actually added a method to control RST on IO2:
} D { ^ } r:4
- } RST (IO2) low to start
- D delay
- { RST high
- ^ one clock tick
- } RST low
- r:4 read the 4 byte ATR
I get
2WIRE> } D { ^ } r:4
RST LOW
Delay: 1ms
RST HIGH
Tick clock: 1
RST LOW
