Hi All:
The hardware is working perfectly up until I changed some codes in the program and load it on the chip then I am unable to program again. The error message is:
JLink info:
DLL: V4.60a, Firmware: J-Link Lite-Cortex-M V8 Hardware: V8.00 S/N : Feature(s) : GDB
- JLink Info: Could not measure total IR len. TDO is constant high.
Anyone knows how to solve this?
Many Thanks!
