Hello everyone.

I’m having hard time unsuccessfully trying to connect to TI TM4C1231H6PZ with ARM-USB-TINY. I’m using OpenOCD 0.9.0, and have the following output:

C:\openocd-0.9.0-rc1\bin>openocd.exe -f ..\olimex-arm-usb-tiny.cfg -f ..\stellaris.cfg

Any suggestions why could I have these errors? Why wrong IDCODE? Must be 0x4ba00477 not 0xffcc001f.

Well, this error was caused by bad wiring. Everything became OK when I excluded intermediate board and cable:
