CCS/TMDXIDK5718: Target connect error

CCS/TMDXIDK5718: Target connect error --- CortexA15_0: GEL: Error while executing OnTargetConnect(): Target failed to read 0x4AE0C204

Other Parts Discussed in Thread: TMDSIDK437X

Tool/software: Code Composer Studio


Hello,
Could you please tell me how to clear my errors and reach main() ?

[My operation]

- CCS740.
- TMDXIDK5718.
- Several AM57 processor SDK RTOS installed:
    processor_sdk_rtos_am57xx_3_01_00_06
    processor_sdk_rtos_am57xx_4_01_00_06
    processor_sdk_rtos_am57xx_4_02_00_09
    processor_sdk_rtos_am57xx_4_03_00_05
    processor_sdk_rtos_am57xx_5_00_00_15
- On CCS
    - Create a new project for IDK_AM571X/XDS100v2/CtxA[ARM]/EmptyProject(with main.c).
    - Build
    - Launch a target configuration file (CCXML)
    - Connect to the A15 core >>>> Error.

[The console output]

My CCS project was attached:

/cfs-file/__key/communityserver-discussions-components-files/81/180829_5F00_JustMain_5F00_ccs740_5F00_tmdxidk5718.zip

[p.s.]

- SD boot was fine.
    - Linux
    - RTOS EtherCAT_slave

- TMDSIDK437X was fine. The similar operation reached main().

    Hi,

    You most probably have code previously running on your target that pre-initialized and protected some registers. This may be either running from a SD card or from code pre-programmed in Flash memory in the board. I suggest changing the boot mode or simply removing the SD card, disconnect from the core and externally boot/reset the board.

    At this point, neither the project nor the JTAG connection are influencing this.

    Hope this helps,
    Rafael

    Other suggestions to try is to disconnect to the target and either:

    -power cycle the target

    -or perform a system reset

    Thanks

    desouza and Lee,
    Thank you very much for your solutions.
    I could see pausing at main().

    In my case the on-board QSPI NOR Flash Memory contained Android.
    I had 2.5sec from reset to connect A15.

    I tried the CCS system reset (Ctrl+Shift+S) and the on-board WarmReset button. Both were successful.
    I liked the WarmReset button for a quick operation.
