Part Number: AM5718
Other Parts Discussed in Thread: AM5728

Tool/software: TI-RTOS

Hi,.

I successfully converted my gel file to c and i just included it to my main function(LED blinking).After 10-12 successful led blink it shows an error message like these..

CS_DAP_DebugSS: Error: (Error -242 @ 0x0) A router subpath could not be accessed. The board configuration file is probably incorrect. (Emulation package 8.0.903.4)
CortexA15_0: JTAG Communication 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 8.0.903.4)

    Hi,

    I suspect that a initialization step is missing. Given that it happens only after 10~12s, my suspicion falls into a watchdog initialization or disable routine.

    Are you using the AM5728 GPEVM board? It features a hardware watchdog that power cycles the device after a similar amount of time.

    Another course of action is inspect the application for any memory leaks that could cause the code to reset the core inadvertently, thus re-enabling the watchdog and causing the device to power down.

    Both scenarios above would cause the JTAG communications to break down.

    Regards,
    Rafael
