Fatal error: Failed to read CPUID for Cortex device

Question asked by kumar.pradeep on Jul 11, 2011
Is this on a board you created, or a commercial eval board?
this is the board created not a commercial eval board, I also have a commercial board on which it is working perfect.

Check the wiring, and connection, of the JTAG port?
Wiring and connection are proper.

Check if you want to use SWD vs JTAG signalling.
I wanted JTAG, but both are not working

Check you have current drivers and firmware from SEGGER.
As it is working on the eval board properly, I feel drivers are installed properly.
