hi, i am working with infineon's XC164CM microcontroller. i could program the flash of the development board through Ulink Jtag adapter. But when i was trying with my own board(not a development board) i could not. the error message i got was " JTAG communication failure". Can anybody help me? Thank You.
Check the schematics in your hardware. The XC164CM is a bit critical since you need proper pullup/pull-down resistors. See: http://www.keil.com/support/man/docs/ocds166/ocds166_pinout.htm Reinhard
