USB SPI Flasher with PIC18F2455 - now with source and binaries

[fatjoe]

"design" is horrible and how this can work without ground ?
lawk it's so hard to build something like this :

Do you have schematic for this?

It's the same as this: http://www.xboxhacker.net/index.php?topic=12306.msg87732#msg87732

@rolf2
nice, could you upload a picture of the bottom side?

Where are the capacitors for your crystal/vcc etc?
Resistors for pin 1/26?
Ah Found them :-)

ok no problem - here is bottom of my pcb , but i dont understand why you need this..., just folow initial diagram ...

For folks just popping into the thread, go back to page 4 or so and read ahead - there are a bunch of variations on the original diagram if you find some hard to read. Also, see this post if you want the most recent hacks (won't even call my mods to this coding) to DarkStarTM's excellent work, the V3 binaries in the opening post are not 100% accurate to the included diagram and pin function descriptions.

Here is the result of some reversing I did a while ago. Basically better nand detection than looking at the config register for specific values.

Excellent, thanks Redline99; this is actually something I should be able to implement and test on my own falcons.

Your flashconfig is wrong, it couldn't possibly work. You got a wire mixup, a bad parallel port for this, or the wires are too long.

I shortened my wires, checked my wires and now i just get error 0 every time and a flash config 12fe2c (what should a good config be)

[CyberPK]

That's my board.
Fully working and tested with cory1492's binary and NandPro v2.0b and a 16Mb flash.

[damn!]

How do I have to flash this? I don't have a PIC Burner, i was buying it allready flashed.

Can someone please help me?

If the person you bought it from followed the instructions it should be possible for you to get into the usb bootloader, from there you can flash the chip with the new firmware.

All explained in this thread

How can we use USB programmer (PDFSUSB.exe) to reprogram the PIC after the first time that we programmed it?
The first time when there was only Bootloader on the PIC, PDFSUSB.exe recognized the USB device and I could program it with PICFLASH.hex but after that when ever I connect the USB cable and start PDFSUSB.exe, it doesn't recognize anything!
Do I have to use ART2003 to erase the PIC and reprogram the Bootloader again?

[maximilian0017]

You can connect pin 17 to ground (jumper in Sandugas his image) and it should be recognised by windows as the bootloader, then you can reprogram it.

If you have a very old version of the bootloader it could be a problem if i remember correctly....again is mentioned in this thread.

Finally i have the PIC, and i built the "mini" version in breadbord exactly like i draw here ---> http://www.xboxhacker.net/index.php?topic=12306.msg84955#msg84955
The only modification is that there is no trace between PIC legs 8 and 19 (this legs are ground, and are connected internally in the PIC)


Bootloader writed with winpic800 v3.64 & ART2003 PIC programmer
PICflash writed with PDFSUSB.exe with the PIC in the USB circuit (some functions of PDFSUSB.exe crashes for me, like "erase"... can somebody verify this?)
Both, bootloader and PICflash from PICFLASH_v3b_plus2 package

Bootloader & jumper working OK:
JUMPER ON - Device detected as: Custom USB devices/ Microchip Custom USB Device
JUMPER OFF - Device detected as: LibUSB-Win32 Devices / Memory Access

I had no fails while writing/reading several times a xenon 16mb nand (making single block, and full dumps, binary comparisons)
It works normally with XD cards 16mb in a XD socket (card inserted in the 360)




Edit:
The real photos at full size

The ART2003 ghetto programmer (i move the capacitor here because i was having problems with it...but can be soldered in the db25 directly)

*dont take care of the numbers i wrote in the corners of the PIC... 15 & 28 are wrong numbered... ops (but the wiring is ok)

[damn!]

Mhh, then i belive this is my problem, as it doesn't get recognized... So i have to burn the whole PIC again?

The version v3 of the bootloader (the one that is posted in the first message) is reported as buggy
There is a conflict with the bootloader mode function (and another function that i dont remember)... this blocks the "bootloader mode" and the use of the jumper

The only solution seems to be to write a new bootloader with the PIC programmer and the PIC programmer soft (not the usb circuit and PDFSUSB.exe)

[cory1492]

With the proper bins you don't even really need the jumper anymore to get to bootloader mode, just need to use a python command

It's also a quick way to tell if you have the proper bins installed if you have python.

[damn!]

So i tried it now with a LTP interface and it's still not recognized. On a Xenon board i have, both USB and LTP it working perfect.

I don't have any ideas what could be wrong, another Falcon i had was working wothout this problem.

[joeyddr]

Anyone willing to trade one of these pre-made? i have a couple of xenon nands i'm willing to part with, perfectly desoldered.

[TSX1]

How long does it take to Read a 256 or 512 MB NAND flash ( on Jasper M/B)?
I know for a 16 MB NAND it takes about 6 minutes with the USB programmer.

You certainly post some useful information here for me   could you please post a diagram of ART2003 ghetto programmer?  I cant make out what lines are joined in the picture you posted and what diodes are joined.
