GENERAL JR Programmer Reading Writing Speeds?

[dantok]

Hi All,
I`m just wondering, i have the J-R Programmer, however it doesn't seem faster than my Normal SPI Reader.

Any ideas? The speed seems similiar? am i doing something not right? Or is there a way to read the nand faster.

Probably grab a NANDX, will it read as fast as the Demon? Like 23 seconds?

The J-R Programmer should be faster than original USB devices. However with the development of J-R Programmer V2 - speeds have been dramatically improved. Im sure Ubergeek said there is an addon for V1 being developed to bring its speeds in line with the V2. (it wont have all its features).

No. The DemoN reads the NAND directly, the NAND-X uses SPI which I believe goes via the Southbridge.

As BraveH said, v2 is in the works and will bring the JRP up to speed with the NAND-X (if not faster) .

Its not as fast Blakey but its close to Nand-x speed (a big improvement on v1 speeds)!

Hmm! seems like i should invest in the nandx, since i thought JR was suppose to be 80% of the NANDX but it's still slow And i do heaps of sets a day, waiting time... AH! lol.

What kind of dump time should i be looking at for a full 16mb flash? I`m sure there are many NandX users here

 

[BraveH43]

the 80% thing was incorrect and amended.
v1 gives average times of 5 mins 30 seconds
v2 is a lot faster
so wait a while for v1 addon (or get a v2), you'll be amazed and the jump in speed!

I can tell Nandpro to do 4 16mb NAND dumps, go make a coffee, come back and they're done.

That's with a NAND-X.

Holy sh*t, that's fast. OKAY i`m getting a NANDX, since i do heaps of RGH's a week. waiting for it to dump... *goes crazy* lol Thanks for the info guys!

The 80% figure was a mistake it's more like 50% but at 50% of the price too - that will all change with JRP v2

If you do 'heaps of sets' a day then how could you even consider anything less than a NAND-X ?

This device is almost 4 years old which rock have you been under ?

Do bear in mind I like to have a smoke break while I make my coffee... so it's somewhere around 5-10 mins for 4 dumps of a 16mb NAND (I haven't actually sat down and timed it properly)

 

[dantok]

lol, i`ve been using something i cannot mention.

Before RGH became possible, i was using the LPT to SPI JTAG points. to read flashes. (YES I KNOW THEY ARE DAMN SLOW)

It didn't seem to make sense to buy a proper programmer, until the RGH came out.

And it was $90 for the NAND-X. which was costly. Now on the other hand, i have a distributor account (can't say price, might get killed). I`ll probably get one, but they didn't have stock. Hence i wanted something faster than the standard MicroCHIP USB flasher, Guess it's time to invest the nand-x. It's alot cheaper when you have an account

I don't recall nand x ever being 90 dollars. I had mine for years think I got it for 40?

Perhaps that's due to conversion between AUD?

I have no complaint with the speeds of JR Programmer. I dumped 66MB from my 512MB jasper I did 2 of those at about 20.43mins each I think and wrote back the same image and it took a little over 23mins.

Nand-x Speeds

Falcon 16MB - 2:06 = 2 mins 6 seconds

Jasper 256MB dumping 66MB - 5-6 mins something around here, if i remember right could be a bit longer but not much.

all SPI flashers should be the same unless they have some sort of turbo mode

JR-Programmer is still new so might be a bit slower then nand-x but next version should keep up with the nand-x & be able to do more then the nand-x

-----

but as stated Demon is direct so it only takes seconds not mins.

Would be nice if JR-programmer v2 would be like the demon!!! maybe thats the JR Turbo v3. or JR instant flasher lol.

----
if the JR-Programmer was made like the demon or had a mode on it to do so, maybe just an option you could use & still have the extra features it's packed with.

could open a whole new world, like adding 1GB nands to PCB & adding multi banks something like xbox1 if possible or adding an os or something. just saying many possibilities if nands could be larger & used offline & undetected.
