[HOWTO] flash your jalapeno to 8+ ghs

[Zanatos666]

Ok thanks and you have less hw errors?

Yes, but I think part of that was because it was running hotter with the case on. Now that the case is off, and even flashed, it's running cooler than before.

Not sure if you've done it or not, but with the case off, make sure to turn the fan around as well so it's blowing down instead of sucking .

Absolutely did that.

A word of note as something we discovered, if you dont have a JTAG cable and need to use a IDE cable, if your unit is a heatsink unit, and your IDE cable is right angled, you can use your heatsink to keep the chips cool during flashing.  You dont need to even cut the cable, just let it hang over the side, and make sure that the pins match up on your Dragon, which will also have the cable hang off the side.  This will save you from having to hold the back plate on the chips when erasing and programming.

Are you saying install the cable and add back the heatsink and leave the cable?

Does anyone know if I need all 10 pins? I want to use clips and it would help to skip some.

Yes, put the cable on and then put the heat sink back on. The cable will obviously hang over the edge, but there is plenty of clearance for the heatsink to be out back on to keep the chips cool as they fire up when you plug the unit in.

Would this device be suitable for reprogramming the Jalapeno?

There is even an alternate firmware available which makes it a STK500 v2 AVR programmer clone.

you better get Avrdragon work with Avr Studio 6.0+ and you wont get more headache with it.

if everyone thinks that they can get away with using another jtag programmer then go for it dont ask! 

otherwise its prolly a good idear to use the AVR dragon

[bitpop]

Yeah the Dragon isn't much more from mouser

hmmm i havent even check mouser... good lookin out! i get great deals from mouser.

Seeing that the Atmel AVR Studio 6.x is not available for linux....
This same process can be completed with the Atmel AVR Toolchain .... correct?

I'm trying to avoid actually having to install windows to do this :/

You could try the old Linux version of AVR32 Studio (2.6.0). Maybe just for flashing will be enough.
Still haven't received my dragon board so I didn't tried that yet.

So nice one..... i just killed my jala today
i did flash the firmware from ckolivas , all was fine till then.
Plug in and the Jala wants to run with 60Ghash......only HW errors.
Then i tried to flash the 1.2.5 firmware and he did 500 Mhashand froze after 5 minutes.
Tried it several times and no its dead. Cant flash the firmware any more, the atmelchip gets hot, all leds are lightning.

So i waited 9 months and now i killed it.

Did you update your mining software?  I had all HW errors after flashing, had to update BFGminer.

Have you tried using the hex that is originally released from BFL?

...
WHAT YOU NEED:
source code from BFL
https://forums.butterflylabs.com/announcements/3282-bitforce-sc-firmware-version-1-2-5-a.html
and/or
the .hex file from BFL, just in case you have trouble compiling it (I did initially).

Sorry in advance if this is a noob question. But how do I find my chip count, firmware, MHz on win 7 64-bit CGMiner 3.3.1? I see you can ask the api but I have know idea about api's.

"java API stats" for local machine but need to launch command from CGMiner directory so take command prompt to wherever you installed 3.3.1 then type that enter and away you go.

[Joshwaa]

Thanks for the help.

My Jally :
PROCESSOR 3: 15 engines @ 252 MHz
PROCESSOR 7: 15 engines @ 252 MHz

I think I will just let it be. Doing a good job as is.

More the point, you can't kill it unless you screwed something up yourself.

i.e. short something out, connect something the wrong way around, connect the wrong hardware, try connecting live hardware to live hardware etc.

The Atmel chip itself can be erased back to blank and reflashed if the contents get messed up.

I thought my howto was pretty easy to follow

Edit: though if you weren't using cgminer that pays close attention to the temperatures ... you may have screwed it up that way

Can I ask you what kind jtag were you using on your Jal?

[Sukki]

Jtag 1   10 pin  why?

[tom99]

  Are you using AvrDragon programmer with Avr studio 6.1?
