[Answer]
There may be the following causes.
- The setting value of reset vector address and the reset vector of MPU are not matched.
(You can confirm it at RESET tab on MPU-specific settings.) - nSRST signal of ICE does not connect to the reset signal of MPU.
- nSRST pin is not assigned to JTAG connector of the target.
- Because of the specification of the target or MPU, JTAG communication is not available while the system is resetting.
(Such as nSRST and nTRST is connected in an OR condition)
If the all of above are satisfied, you can use the reset vector break function.
If you want to do the reset vector break when issuing the reset command, make sure to select the reset vector break on RESET tab of the MPU-specific settings.
