Hi JTAGers,

I'm trying to revive my SIMpad with JTAG after killing it with the 
hh.org bootloadr.

When I run detect I get different results each time. Whenever I get a 
reasonable output I move on to detectflash and I always get "Flash not 
found!"

jtag> cable ppdev /dev/parport0 DLC5
Initializing Xilinx DLC5 JTAG Parallel Cable III on ppdev port /dev/parport0
jtag> detect
Device Id: 00100100100100110000000000010011
  Manufacturer: Intel
  Unknown part!
jtag> detect
Device Id: 10011001001001100001000000010011
  Manufacturer: Intel
  Part:         SA1110
  Stepping:     B5
  Filename:     /usr/share/jtag/intel/sa1110/sa1110
jtag> detectflash
ROM_SEL: 16 bits
Flash not found!
jtag> detectflash
ROM_SEL: 16 bits
Flash not found!

I've checked and double-checked all contacts from the test grid to the 
end of the JTAG connector. Everything is O.K.
Oh yeah, I made my own cable from the instructions at sf.net. And yes it 
is very short (~20 cm.).

I would be thankful if someone can help me out on this one. Otherwise my 
SIMpad days are of the past.

Chris
