USB SPI Flasher with PIC18F2455 - now with source and binaries

[sandungas]

Hmm.. Not sure if Im blind or what but why cant i find any pics from programmer 

I dont remember exactly, but in the readme (or in a link in the first post) there are 3 links to 3 different programmers
The easyest one to build yourself is the "art2003" (is a .pdf) you just need some diodes, 1 or 2 capacitors, and not much more

If you use this programmer... in winpic800 (the programmer software) there is 1 option to select the art2003 (winpic800 & art2003 are fully compatibles)

This is the easyest way to build this, and more people has used it

Thanks! Found it.. I tried reading that pdf but i dont understand how to count pins on pic boards In that pdf they counting system is very confusing.. So if someone could clear that for me.. Then ill start building

Is there something new about flashing 256 and 512MB NAND with USB now?

[iNsAiNoNe]

It not possible to order from ebay for me But i found PIC18F2550-I/SP from local store So is it as good as  PIC18F2455?

thats where i get my pic chips   FREE!

Yeah, but if you are anything like me they give you one of these.

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

Thanks Grim! So I just check pins name and connect it to right lpt pin according to art2003 programmer tutorial.. I dont have to care about pins number just its name, right?

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

The "News"; Somebody with a 256/512 Jasper is going to have to fix "the issue". Until someone with a 256/512 Jasper is inclined to do so, anyone else with a 256/512 Jasper who isn't willing to do the work only need know: apparently read is working (or appears to work), erase seems to be working (internally the apps erase before write), write isn't (dumped data after a write is apparently only erased, no write - see erase.)

Consider this tool not useful or only partially useful (again, someone with a 256/512 Jasper needs to confirm partially useful) for the time being on Jasper.

All of which has been said in this thread already, just in fewer words. Not much else to "talk about" after that.

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

[G0t m4xx 21]

Hmmm currently at my work I am writing USB to I2C/SMBUS firmware for the Silicon Labs C8051F34x microcontroller (I'm basically copying a DeVaSyS USBI2C/IO to be embedded into our prototype PCB). These parts also have hardware SPI (built in control registers, buffers, interrupts) as well as USB, I2C, serial, 4kb ram, 64kb flash, etc.

I have a few of those DeVaSyS boards laying around (the new version with the C8051F340), the programmer, and the Keil 8051 C compiler, I'm going to take a look at that PIC source and see if I can't port it to 8051, and run it on a reflashed DeVaSyS USBI2CIO board. Probably a lot more work than just getting a PIC, but I could use the programming experience

[MRA]

Could someone please edit the first post, so that everyone knows that these binarys in the V3 archive are NOT working on a 2455 as they are supposed to?! Yesterday I spent 4 hours messing around with my circuit because I thought I had wired something wrong before I read the whole thread and found out that Cory has compiled newer binaries --> Downloaded them --> everything works! That would have saved me al lot of time. Also I think a hint on this could be useful too.

[ernestino]

I have done everything according to ColtB45`s post.
I use 18F2550. Programeed PIC with PicxBoot_12.hex, then flashed PICFLASH.heh with PICDEM.
Picdem failed to reset board. If I reatach to USB new device is found - Memory Access, but no driver found.
Where can I find driver?

Thanks

[cory1492]

Where can I find driver?

The libusb/Mem Access driver is in with nandpro, if you need 64bit look through my previous posts as the one in nandpro doesn't seem to install properly on newer 64bit OS.

[Grim187]

MRA: You could have just used nandpro2.0a.

[ernestino]

I have problem reading nand - after a minute or so i got only errors:

D:\nandpro20A>nandpro usb: -r16 nand.bin
NandPro v2.0a by Tiros

Looking for usb interface device
FlashConfig:01198010
Starting Block:0x000000
Ending   Block:0x0003FF
Press any key to begin reading nand

- Then blocks are read OK for about 1-2 minutes
- From random block I get only errors
- In a second it ends at:
Error: 399 reading block 3FF

Any advice?

I haven't seen that at all. Are you still having this problem or have you resolved it? If you did resolve it, what did you do?

[ernestino]

No, still the same problem.

Is it possible that it is problem because bad bootloader? I had big problems programming the PIC - I use Kitsrus K149 programmer and have to use fixhex2 to be able to load hex file to PIC. I also had to manualy set fuses to be able to load Picflash.hex with PDFSUSB. After that it is normasly recognized as libusb-win32 device, Memory access and also Nandpro recognize it.

 Hi all.

 I built the LPT Art2003 Pic18fxxxx programmer and it appears to work.

 I select the Pic 18F2455 as the device to use, set the oscillator as "divided by 3 (12Mhz input".  The usb circuit is using the default 12Mhz oscillator so i believe i am using the correct setting.

 I selected the PicXboot_12.hex as te file to write to the PIC and it writes ok, i select verify and it shows code,ID,config and Data as ok.

 Now i am confused what to do next.  Do i attempt to program the picflash.hex to the PIC while still in the programmer? or do i now remove the PIC from the Art2003 programmer and put the PIC in the usb circuit, connect it to the PC and continue on from there ?


thanks
