Can you reprogram the boot loader to the PIC? Are you using the correct frequency for your board? What type of crystal/resonator are you using? It could be a damaged PIC or somehow the payload overwrote a part of the boot loader (which is unlikely).

Don't have access to pc with lpt or com port at the moment, but i'll try to reprogramm the bootloader out as soon as possible. The resonator is 12.00 MHz with two 22pf Capacitors (used the same resonator\capacitors when built psgroopic dongles, they all where working, so I think it's not the point).
This can be a dead PIC, but I think it's not, but have some PICs left so will programm them too when I'll get to programmer.
P.S: can't find a camera to post pictures of motherboard with connected wires, but I had rechecked that like five times and I'm sure it's right.

either my comp and every comp in my house is retarted or this doesnt work at all.
I have rebuilt this 4 times everything is correct but every single time i plug it into my computer it comes up as an unknown device and wont let me install drivers for it. I go under device description and the hardware ids are "USB\UNKNOWN"
I have gone WAY over what it would have cost me to just buy one, I have absolutely no clue why it doesnt work. Any and all help is greatly appreciated.

I have a PSgroovePic with bootloader and I want to adapt it to xbox 360 USB nand flasher, but it is built with 20mhz crystal. The original PICFLASH.hex uses the 12mhz crystal, will it do the job if I record it to my device with 20mhz crystal? Or do I really need a "PICFLASH.hex 20mhz version"? I hope someone has a hex file like that, otherwise I'm stucked by now.

If your groove has the microchip bootloader you should be able to flash just the application hex. Having the crystal setting is only important if you are reprogramming the PIC fuses, so long as you don't let it reprogram them your bootloader should (hopefully, there should be a pin or button to force it into bootloader mode) always work. If you need an app hex for HID bootloader, that is possible too.

@cory1492 Thanks a lot for the fast answer! My psgroove does have the button to force it into bootloader mode, yeah!  . I normally use Microchip PICDEM tool to flash it.  You helped me a lot, it's very good to know that it will work despite the 20mhz crystal. \,,/ EDIT: I did it and everything worked like a charm! See some pics of my PsGroovePIC to Xbox Nand Flasher adaptation :    Once again thanks a lot cory1492! |

Hello, I have a problem, the programmer is detected as unknown device by usb on the motherboard m4a88td-usb3.0 but works fine on another old motherboard. I tried to connect the programmer to a different port and disable support for high-speed usb port. Clock frequency is present, flash and pull-up resistors are normally

I've built the usb spi flasher using the 18f4550 - I've got the boot loader on the PIC and programmed it using pdfsusb. After connecting it to the PC I get prompted to install the drivers and all seems to be working. It gets picked up as LibUSB under devices. I've wired it up to the xbox (falcon) and run nandpro which starts reading the nand and then a few seconds later (after it gets to around 3F) I start getting tons of error reading blocks. The LibUSB also dissapears under drivers. If I run nandpro again I get no device found. I have to unplug it and replug it in and then it gets detected - but I get the same errors. Any ideas where I could be going wrong? I've trippled checked the wiring. The PIC is also good as if from a ex PS3 JB I build so I know its working. The other thing I notice is that if the xbox is not wired up to the flasher and I plug it in - it gets detected and can see it under devices, but then a few seconds later it dissapears from the devices. Is it supposed to do this? Update: Bah humbug! A few hours later and its working. I clearly didnt check the wiring enough - pin 13 needs to be taken to 5V!!  All working 100% now  |

I got the same issue with the connection losses on a nand flasher I used on several consoles just fine a year ago. I get disconnects after reading a while, sometimes it will actually go through without error, though. Pin 13 definitely has 5V. I resoldered everything, tried on a pc and laptop, checked all wiring, added extra caps for filtering.. no go. Any ideas?
Edit: Nevermind, likely caused by R7 (10kohm resistor on pin 26) being broken, replaced it and it did a few reads and writes fine.

I do NOT give support by email, PM, ICQ or whatever. Anyone annoying me that way will have his balls removed. With a rusty butterknife. Slowly. And I'll enjoy doing it.

Good day Forum.
I built a darkstar nand flasher using a PIC18F2550, and im trying to load the usb bootloader with my PICKIT 3. The bootloader is responsive, but the problem is that it is stuck in bootloader mode, ALL the time! I tried setting MRCL, LVP etc etc. My circuit is correct(The bootloader pin only grounds when i push the button, checked it with the multimeter).
Does someone know if I should relocate the memory in MPLAB's to get the bootloader to run only when pushing the bootloader button? Hw do I fix this please help!
Thank You!
Regards

question is, did you even flash the picxflash? it will always be in bootloader mode if the bootloader is the only thing on the chip. |

Hi Illness (Respect for work on PS3 scene, that was epic) Im using a PICkIT3 and MPLAB to flash the PIC. I loaded the bootloader successfully(Bootloader always enabled, pin 17 grounded or not), and when I reprogramming it using the PICDEM USB FS Tool it programs flashX successfully(I detect memoryaccess in device manager), but then I have no more bootloader. I cant use PICKIT 3 with LVP(microchip made it obsolete), so do i need to perhaps change or ground pins when programming the bootloader or what can I do!? Thank you, very frustrating having more problems with expensive pic programmer, my old ps3 art2003 worked better Good day Forum.
