[HOWTO] flash your jalapeno to 8+ ghs

[lightfoot]

Speaking of which, I have two jalapenos running at 28gh now with more chips. Both need extra cooling; you can take a stock cooling system up to five chips without anything, six chips with small copper heat sinks on the FETs, and seven chips requires either water cooling or a big heat pipe.

I wonder about 8 chips :-)

so im guessing only 2 chips

i had been running it under cgminer and that was reporting a steady 8.2gh/s after running for a couple of hours. this is bfgminer output after 4 mins.

i presume then these boards can take 8 chips in total? assuming cooling and power could be dealt with.

how easy is it to see what firmware revision im currently running ?



thanks again for the advice

monkey


and again after another 5 mins or so

Interesting. Can you go back to cgminer and see if the speed goes back? I'm wondering about that a little bit.

but its only been up for a little while, after running it for the first time i came back to it several hours later, the next morning. Ill see if its gone up more and report back !

anyone out there in the UK that can mod these things ?


both cgminer and bfgminer are latest versions, from git as of a couple days ago and running on a pi

[lightfoot]

To be honest, it's probably not worth a flash, however there is a guy who can do it remotely if you have the programmer. You have replaced the POS power supply with a locally compiant one, right?

C

[monkeynutts]

Yea didnt like the look of the psu the moment I set eyes on it !

I was thinking more of adding chips to the board, if anyone in the uk would be able to do that, I have everything in place to flash the unit, from my pi, but as i was seeing such good numbers ( as im writing this its running at 7.7 avg ) I started to think twice, hence my posts here.

Miners for me are more a hobby than a profit maker Im willing to take the risk to boost this little pup, I have been inspired by your efforts but sadly i lack the ability to do it myself.

Hell mabye ill splash out and get whats required.

7.7 GH/s avg for 2 chips is nice (on stock? interesting to see what firmware you got??)
You might think you can flash it via USB, but you need an JTAG programmer such as the Atmel AVR DRAGON afaik...you have that?

[monkeynutts]

I never said I could flash it via usb. I have a PI and a home made cable as outlined earlier in this thread, AVR dragon not required.

Unit is on "stock" firmware, that is to say I haven't flashed it so I dont actually know what version its running sorry. Any easy way to tell or will i need to hook up the pi ?

Most BFL products have a sticker inside the unit, sometimes on the base plate, with the version number and production details.

[monkeynutts]

Thanks ill take a look this evening.

At the risk of playing Captain Obvious, I'd start with a lower JTAG clock speed and work up if that connects okay.

Update: Wondering over. Can do 32gh. With 8 chips you need a water cooling block and a big power supply, but it is fun!

I flashed two jalapenos yesterday with the 1.2.9 firmware.

Got some strange results on both:

These two shipped together in one box, I bought them used. I'm guessig they are fairl early as the heatsink leaves room for the jtag cable.

they have 1256 chips not 1128.


The first one I flashed without making any changes in the firmware and it hashed at a steady 3740...

So I went back into the files and changed it from a single to jalapeno in the std_defs.h.

It hashed at 6745, 7740 and 8812 cycling between the three exact rates.

I went back in and altered to a little single and nothing changed.

So I went back in again and altered it to a Jalapeno and the frequency from 33  to 64.

Tested it and it now cycles between 7891 8898 and 10126.

Used the exact same build on number two and it cycles between 6665 7490 8812.

Wondering what is going on and what I did wrong?

Hardware errors on both after 24 hours are low 76 on the first one and 188 on the second.

They are not in the cases and have a 120 mm case fan on top of the heatsink. Before flashing they ran at 33 degrees and after they are running 41.

I'm amazed it worked, need to do little_single or jalapeno.

Tested it and it now cycles between 7891 8898 and 10126.

That's really weird, how many chips are reported in bfgminer (use D, then M to show the chips)

C

[otsaku]

bfgminer can't find either. I'm using cgminer instead.


little update, after trying to start bfgminer and then returning to cgminer the first one is swinging between 8.5 and 10.7 and the average is showing 9.1.


I maybe should have mentioned that I bought these as 5ghs and one has run rock steady at 6ghs and the other at 6.5ghs with some amazing spikes on start up, up to 43ghs.

Avr dragon shows number one 3.3v

and number 2 3.2v.

Nice thread =) So i had to flash my jalapeno too =) But do i get too much HW errors?

HW / (A+R+HW) =
1359/(12342+117+1359)=0,0983 = 9%
That's after 2 hours of mining.

Should i go back to BFL original 1.2.5?

Cheers for the nice work from everybody =)

[lightfoot]

Eh, as long as it's hashing I would stay with it, especially with two chips.

When you have 8 chips on a Jally, you want to tune it down a bit for no errors. Reason being that errors cause heat, and heat will drive you bats with an 8 chip unit.

Mine as much as you can. And good job boosting it.

So it's not better with 7.2GH/s with 1.2% HW errors instead?

[lightfoot]

I tried to flash my faulty jalapeno with an AVR DRAGON, the good news, the mining software detect it but the bad the hash rate = 0 ghs.

I tried different firmware, would it be possible for somebody to share with me a right firmware for model 1256 model please?

Anybody can help me on this?

Just what did you flash? A stock jalapeno should be flashed with the 1.2.9 code compiled either for AVR 128 or 256 (to be honest if you compile 128 it will work on both types of chips), and make sure you set the device type to "LITTLE_SINGLE" and not "SINGLE" in std_defs.h.

If you're totally sunk send it over and I'll fix it for you.
