cory:
i have no problem on test your "test program" on mi jasper 512...then i will share mi experience about it...thanks, federico

i have a 512 and make a dump of the NAND and i can confirm the following:

-Read: "looks like it works" (but when i flash the backup using LPT the system does not boot, i flash it 3 times) so the read may be is corrupted (this is extrange because i do 3 dumps and the 3 are identical on TOTALCOMANDER...next time i will do one dump from LPT and one from USB and will compare bouth
-Erase: works
-Write: doesent worl at all...simply delets every block

(the strange thing is that the USB interface works perfect with xenon and falcon 16mb)

by the way i dont know anyting abou programing so...the only way i can hep is sharing mi experience...but i can fix it...i think that the person how do the picxflash_v3 know more about this and may be he could help....and by the way anyone know if the LPC2148 (recomended in the NANDPRO txt) have the same problem???....tahks, federico

yes, is there any news about flashing jasper 512 and 256 with USB???...why nobody talks about it??

is there anyone working on a new version of xbox tool that suports jasper 512 and 256 NAND backups?

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...

can a use a 18f2550 instead of an 18F2455???, whats the diference???, i cant find an 18F2455 here in argentina, thanks, federico

sorry if this is a noob question, but can i just flash the chip with the PICFLASH.hex whit a PIC prgramer without the need of first flashe the bootloader???

PS:sorri for mi english
