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"
