Well I seem to of royally cocked up the Ras PI method every time I use this hex file for flashing https://dl.dropboxusercontent.com/u/143860/BitForce_SC.mrrad.hex the process shows the following

Flash on AT32UC3A1256
Size(detected): 262144
Pages: 512
Page size: 128 words
burning...
addr: 0x8003FE00 page: 511
verifying...
addr: 0x8003FE00 page: 511
511 bytes total
Done.

I then run the following commands

jtag> instruction HALT
jtag> shift ir
jtag> dr 0
jtag> shift dr
jtag> shift dr

this should then start the front LED Flashing but nothing happens.

and CG miner says it is unable to start the device

Any ideas?

edit: I do not know how to compile firmware with atmel studio

edit 2: i found with the LED's on the back that are on are the one next to the power power connector and also if i remember correctly the 1st LED on the left (i belive these are the active chips LED's) this may help some one diagnose my issue

you need to change file .hex to .bin. you need to read over again for Ras pi by Redxxx information

here link http://randomcontent.wolfnexus.net/RandomSite/reflashing-a-butterfly-labs-jalapeno-with-only-a-raspberry-pi/

you might missed this step "pi@raspberrypi:/usr/src/urjtag/urjtag# srec_cat (path to .hex file) -intel -offset -0x80000000 -byte-swap 4 -o (path to output .bin file) -binary"

Agreed on the last step there. If you have done this and its still not working, I notice it only seems to be flashing about 500 bytes, this should be about 262000 bytes. Maybe re-download the flash file and try it again?

you meant .bin file is 262000 but not after jtag done with programming

ps: here from your site:
"Flash on AT32UC3A1256

Correct... The flash detected size is the 262k bit, the firmware size is roughly half that... Sorry people!
