DRV8343S-Q1EVM: F280025C_UNIVERSAL MOTOR CONTROL PROJECT FOR BLDC USING DRV8323 COMPILATION ERROE

Device register

This error means the JTAG debugger is unable to access the core or device on the board.

Technically speaking, this happens if the JTAG debugger fails to access an ICEPick register (exceptions are MSP430, Stellaris and some C2000 Wireless connectivity and Digital Power MCUs, which do not have an ICEPICK). If the ICEPick driver reports this error immediately upon connect, it's likely a hard fail with the JTAG connection itself (loose cables or connections, etc.). However, if the error happens later in the debug session the reasons are different (perhaps the reliability of the JTAG connection due to noise, or improper firmware that causes the device to power cycle or reset, etc.).

This issue can also manifest itself if the Debug Probe senses the scan path is broken. Some troubleshooting tips can be found at the section Invalid data read back below.

In certain scenarios the loaded code may cause issues with the normal connection and/or execution. In this case, check the troubleshooting tips in the error Invalid device ID below.

Additional tips to properly debug and correct this error are also in the section Troubleshooting the connect phase above.

    Error connecting to the target:
    (Error -2131 @ 0x0)
    Unable to access device register. 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).
    

Dear manaj

Now we can flash the program  to ECU but we can

1. when we connect programmer and without 12 v power supply  we can successfully flash the program to ECU , also debug happening 

2, during the time switched on 12 supply MCU got reset 

3. when we connect 12v and trying to flash program to ECU immediately got below issue, please give solution
