Hi sir

I try to exercise Task 2 Connect and Navigate Exposed services followed by the website

http://dev.ti.com/tirex/explore/content/simplelink_academy_cc13x2_26x2sdk_2_40_01_00/modules/ble5stack/ble_01_basic/ble_01_basic.html

, and I connect two LAUNCHXL-CC26x2R1 kits connected to PC, using simplelink_cc13x2_26x2_sdk_3_10_00_53, one download the host test.app, the other download the project zero.app

First time, I success using BTools, but cannot search for the Project zero, then I try to download the host test for a second time using CCS9.0.1, than comes out the error

In CCS console, the following error appears after I open the bTools.

Cortex_M4_0: GEL Output: Memory Map Initialization Complete.

Cortex_M4_0: GEL Output: Board Reset Complete.

Cortex_M4_0: Error: (Error -1170 @ 0x0) Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 8.1.0.00007)

Cortex_M4_0: Trouble Halting Target CPU: (Error -2064 @ 0x0) Unable to read device status. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 8.1.0.00007)

I just use the onboard probe and do nothing change to the HW, so I checked the target configuration
