[HOWTO] flash your jalapeno to 8+ ghs

[Techknowledgy]

I'm planning to flash my jalapeno , only thing I want to ask will I have any trouble running it with bfgminer or Bitminter clients after the flash because I am having trouble running my jally on CGminer now ?? In other words will doing the flash force me to use CGminer only   ?...Thanks

No, nothing should change.  But I am curious as to why/how you are having problems running one with one client and not the other.  The only thing that would be a difference is making sure you have the correct driver.  I used to use my jally on Windows and ran it with bfgminer just fine.  I run it now connected to a BAMT rig running cgminer, and again, no problems. On Windows however, if you want to use your Jally with cgminer you will  need to change over the drivers to winUSB using zadig.

I have been trying to get it to run in CGminer ,I've tried zadig and it detects 0 devices , I have no problem with BFGminer and Bitminter ..  The poster above has got me worried about using ck's firmware because he says it doesn't work with  bitminter client anymore which I like , would it be safer for me to just use the Bitforce original 1.2.5 ?  Thanks for any input........im getting 5.8 without errors running out of the case with fan blowing down now............

The official BFL 1.2.5 didn't work on Bitminter for me either. I flashed up to the BFL firmware and tested it out and then went to CK's version.

EDIT: This might be elementary, but did you choose the List All Devices section in the Zadig menu?

  Thank you so much , that was it ........

[Techknowledgy]

Thank you so much , that was it ........

Glad I could help!

BTW, if you need to go back to the original driver I don't think you can do it from Zadig. I go to the Devices and Printers section in Windows and just rollback the driver.

[mrrad]

Well it was hashing on cgminer and lost connection and now the bitforce sha256 sc usb driver wont work with anything, ive put the FTDIChip CDM Drivers back on and I am back to bfgminer or bitminter... So what I have to find out if the FTDIChip drivers work or not after the flash , basically Im stuck using the usb serial port driver (com3)....?

Bitminter is down right now so that's part of it. Maybe try uninstalling the device and then plugging it back in to start fresh again?

[mrrad]

It's just the website not updating I think cause im still going on bfgminer... i put the zadig ones back on and  they just close up after I enter the pools details... Probably could do with a reformat but not in the mood really.....  So now can anyone tell me if after they flashed their jally does the FTDIChip CDM drivers  ie:USB Serial port (com3) still work after flashing the jalapeno to either ck's version or 1.2.5  Thanks to all , I just don't want to brick it    ................. It's these drivers http://www.ftdichip.com/Drivers/VCP.htm that I want to know work after the flash.............. win7x64

Of course ftdi still works. Zadig is completely client side.
You also must be using latest cgminer

As a courtesy and to avoid double posting, here's a link to another post I made which might help people out if they want a faster / less intrusive / different way to connect their Jaly JTAG to the Dragon JTAG.  In summary, no need to remove heatsink or use JTAG cables, because female to female jumper cables have enough clearance to be attached to the jaly in situ.  https://bitcointalk.org/index.php?topic=236875.msg2981721#msg2981721

[bitpop]

Yeah I bent my pins and used that

[mrrad]

thanks pop and donkey i got my cable coming tomorrow to try  it looks like my heatsink has a cutout for the jtag i got my jala about 3 weeks ago

[bitpop]

Mine had a cut out for the fan but not jtag got 2 weeks ago

cgminer doesn't use the FTDI driver - it uses direct USB via the WinUSB driver in windows (... Zadig ...)
If it worked before and doesn't work now, then the WinUSB driver was probably screwed up (as can happen on windows with any driver)
Zadig also allows you to re-install the driver.

[mrrad]

I went back and forth several times and can't get that winusb driver (zadig) to play ball anymore , I wanted to use cgminer to find out how many engines I was using .. anyway I intend to flash my jally with ck's compilation and use the ftdi drivers and hopefully get an improvement  of my hash rate's with  bitminter client or bfgminer. I'm getting just on 5.8 now so have high hopes for the flash  .......... The cable that is on kano's tutorial fits on my jally without removing the heatsink   . My heatsink has a cutout around the jtag . I only had to take off less than 1mm from the side of the  female pin molding ... so now I've ordered my dragon .....   Got it done, over 8gh/s now

Don't use 1.2.6 on jalapeno

[Red_Wolf_2]

I had no real issues on 1.2.6 with my Jalapenos... Are there known problems with this version?

[mrrad]

I thought CK only modified the 1.2.5 firmware

[bitpop]

He recently uploaded .6

[Red_Wolf_2]

Reflashed both my Jalapenos now with 1.2.6. Frequency factor set to 7 in my case.

Units together were putting about 14-15ghash, now putting out 16-17ghash on average. Can't complain!

Anyone have an extra AVR dragon that they would want to sell for cheap? Or just lend me one and I'll mail it back to you? I'd like to try this out, but I'd rather not have to fork out $50 at the moment

There are ways to reflash the units that don't involve an AVR Dragon.... If you're game
