user error: reset failed in IAR while and download the debug the lightning_demo project to STEVAL-IDB008V2 in IAR

[Anitha]

I'm using the IAR(8.40.1) for flashing the code(Lightning_demo from stsw-bnrg-mesh package) using stlink. After pressing the download and debug icon i'm facing User error: Reset failed.

But while flashing with BlueNRG1 ST-Link Utility, I was able to flash the code success fully.

At the same time if press on the debug without downloading then i was seeing fatal error: ST-Link, No MCU device found. Could u please help me to resolve the issue.
