I've a processor ADSP-21160 (jtag compatible) connected to AMD flash memory (non Jtag).
Is there a free tools that interface Jtag port trought a PC parallel port and allows to program the flash memory?
Thanks in advance.
what was your starting point, and could your program be extended to load a program into the Sharc memory space and execute it, I take that you are twiddling the bits in software without custom hardware.
sorry about that, I meant you are doing all the shifting of bits and stepping through the jtag statemachine required to implement it via software, without hardware - from a parallel port.
You English is fine, you make yourself understood perfectly.
Indeed, I control directly the state machine with parallel port...
I have also an FPGA on board. I plan to implement the state machine handling in VHDL but it needs more time... I needed a fast solution, in term of developping time :wink:
Do you have info about reserved JTAG registers ?... :roll:
