When I erase flash from which arm11 boot, I can no longer attach to JTAG port of the the arm11. I can still scan-out the the two cores but then jtag_validate_chain() reports errors (see debug output).
With a valid image (that basically set plls, ddr, not etc.) I can attach to the arm11 via JTAG. Can anyone recommend how to debug this one?
