Hi, All,

I have one question about JTAG programming to ask for your help.

Do you know how to access PowerPC's GPRs via JTAG port? I mean if we must use private JTAG instruction of Freescale to access GPRs, SPRs of powerpc/mcu.

I plan to design a JTAG tester to speed-up our hardware design/debugging and mass producing.

Your any help is appreciated!
