Is it detecting as a usb device under windows, at which point you'd install the libusb drivers? Do you have Pin 1 (MCLR) pulled up? Do you have Pin 13 (RC2) connected to USB 5V (it's for usb presence sense - the bootloader doesn't use it, the xflash program does)?
Thank you. RC2 to USB 5V is what I needed. I said it was going to be obvious.  |

anybody had problems with writing 256mb jasper nand??
Tried and when i read back just FFFFF at the beginning = box not booting.
Flashed with LPT =everything fine.
i have the same proble using the USB on a jasper 512mb unind nandpro 2.0a... heres mi experience: mother xenon 16mb...read NAND whit USB...then write xell.bin with USB...everiting woks ok and the restore the xbox with the backup of the NAND and now ists working ok. now with another xbox with mother jasper 512mb i can rad the NAND with no problem, but when i try to write the jasper 512/256-hack.bin the xbox dosent boot anymore...then y read the NAND to see whast on it, and its all ffffffffff....it looks like the write comand doent work on jasper 512/256... anyone caold help, please !!!! thanks, federico PS: Straßenkampf , did you try with LPT and you have no problem or you have the same problem??? PS2: sorry for my english EDIT: i try with LPT instead of USB and works ok, now, i dont know why it doesnt work in the jasper with USB, because in a xenon i have no problem... |

I built the spi flasher like this  1. then i used my jdm programmer to flash PicXBoot_12.hex to the 18F2455 PIC (i changed it to 8 mhz since thats the resonator i'm using instead of the default 12) 2. then i connected the 18F2455 to my SPI flasher and connected the USB cord then installed the drivers from the Orig post http://www.megaupload.com/?d=X6TBNFDC the device shows up as it should 3. run PDFSUSB.exe, select the only device from the drop down, select load hex picflash.hex, click program 4. removed jumper, removed usb, plug usb back in, device is now detected as "libusb-win32 devices, Memory access" 5. opened cmd prompt typed "nandpro.exe usb: -r16 nand.bin" and i receive this error Looking for usb interface device
Incompatible ARM hardware for this version of NandPro
Can not Continue anyone have any ideas? note: on step 3, i also tried to load xspiflash.hex from the nandpro folder and it fails to flash to the 18F2455 PIC |

you have to use nandpro v2.0a, not v2.0b !

Could not detect a flash controller
Fatal Error |

finally got it to read via USB.
an hour later i decided to read the readme.txt in nandpro A and it says no resistors, no diodes needed. my problem was i had a diode on the board @ J1D2.4 from when i was doing LPT. took the diode out and it works fine now with nandpro-a thanks tux. hopefully nobody else makes this dumb mistake!

I have some questions about the shopping list: Why is there a USB cable with both ends type A? What about the LPT connector? Anyone got pictures of the flasher built from the shopping list? sry for the noob questions  |

Hey,
Does anyone know if I can use these:
PIC18F242-I/SP
PIC18F252-I/SP
PIC18F442-I/P
Those are only I can find here.. Thanks for answers..

i have done some looking and i cannot find a schematic to make a programmer using the parts shown in the programmer list ? is there any schematics available using these components ? I have seen other circuits, but i just bought these parts so i am hoping to use them Thanks |

Surely you can't miss the picture 8 posts above yours.
I am amazed at the amount of effort you seem to show.

hi cant get the usb version working ,built the breadboard with pic 18f2455 en 4 mhz resonator,flashed picboot(edited with winpic800 to 4mhz) to pic with my willem from picflashv3,gets regonized by windows as (microchip)custom usb device,then i can start usb program ,its sees PICDEM FS USB (BOOT) 0,load the picflash hex ,press execute and then i get failed to reset board, usb write failed,failed with error 997:overlapping i/o operation,and if i hit program it says usb write failed,fail with error 6,the entry is not valid,is this a pc problem,and do i have to edit the picflash also to 4mhz.i have the bootloader jumper on the board but it is if it is not responding to the jumper,so any suggestions,can i flash both the hex to the pic with the willem or do i have to use the usb programmer?and how do i know that the bootloader is working?

droe: mentioning it yet again, the binaries posted don't work "as advertised" so the reset function from picdem does not work. Using those files you need to deal with the programming jumper and just unplug and replug after programming to get it to reset into user code - or look back through the thread to where I posted a build of what is in git where that stuff is all working. Also, the config settings in this project are only in the bootloader so there should be nothing to change in the other file - if you are getting it recognized as a usb device and/or in picdem then you've set osc. right.
fatjoe: there are alternatives, but it will require work on your part. PIC18F2550-I/SP will be fine, the only real difference to PIC18F2455 is slightly larger program flash memory (the hex should work without modifying anything except osc.)

Thanks for answer! But theres more stupid questions to follow.. What do you mean by modifying osc. ? And how to i do it?

If you don't use the recommended oscillator but rather one of the other compatible values from the data sheet, then before you flash the picboot hex file you will have to adjust the configuration setting to match the oscillator you are using. If you use winpic800 to do the programming, it's as simple as selecting your oscillator value from a drop down list in the config tab.
