PSoC62 cannot reset after programming bootloader

[JeHu_3414236]

I am using J-Link to program the secure bootloader but the chip cannot reset and run the bootloader after programming is finished.  I have to cut the supply power and power on again for the bootloader to run.  If I connect a Miniprog 3 after programming, I can reset and run using PSoC Programmer by pressing the Load from Device button.  What is Miniprog 3 doing to reset and run that J-Link can't?  The device is powered by external voltage and not by the debugger.  This is the J-Link log when it is stuck:

In PSoC Programmer,  go to Options > Programmer Options. Here you will see that Auto Reset of Chip will be enabled. This is what causes the reset to occur in the case when you use a Miniprog3.

When using the J-Link, can you try the command "rnh" (Reset without halting the target) instead of "r" and check? Since you said, turning ON/OFF power supply works, can you try the command "power" and check if it works?

Let me know your observations.

I tried rnh and power and they don't work.  Power is not supplied by J-link to the board.  It is external powered.

[DheerajK_81]

Are the physical connections between the programmer and the debugger in accordance with this?

More information on this can be found in Page#20 of the Programming Specfication​.

Yes.  VDD on J-Link is connected to external 1.8V and not connected to anything on PSoC side.

Just for the sake of understanding,  check if you have connected the Gnd of both the host programmer and target together?

If you see XRES pin functionality, from the picture given above, if the XRES pin of the target is given VSS potential, then reset takes place. 

If the connections are fine, can you short XRES of the target with the VSS(Target Gnd) just for a second to check if the reset works. If so, I don't think PSoC 62 has any issue with the reset functionality. You have to look at host programmer side for debugging this issue.

Thanks.
