Hi all,
I am a newbee to debugging,i have a hardware USB JTAG Debugger provided NGX
Technologies which has 20 pin standard JTAG Header.
But BB-XM has only 14 pins,so i used a pin-pin connection between BB-XM and
Hardware Debugger using Jumper wires between.
1.I have unused EMU0 and EMU1.
2.I have connected TDI of BB-xm to Debugger TDO and vice versa.
i started openocd by changing the tcl/target/amdm37x.cfg cortex-a to
cortex-a8 @144
when i run the command on command prompt : openocd -f
tcl/interface/ngxtech.cfg -f tcl/board/ti_beagleboard_xm.
cfg -f tcl/target/amdm37x.cfg -c init -c "reset init"
it displays the fallowing log on the console
