AM2634-Q1: DMM /RTP debugger interface for Sitara platform for use with Vector VX1000 high speed debug tool

Part Number: AM2634-Q1
Other Parts Discussed in Thread: TMS570LC4357

Hello Team,

On checking the TMS570LC4357 RM we could notice that the controller supported DMM /RTP interface for debugging. However, this in not seen in the Sitara platform.

Could you let us what is the alternative to be used with VX1000 Vector interface, other than JTAG. As JTAG seems to be a slower interface.

    Hello, 

    I apologize for the delay. The AM263x utilizes the DEBUGSS for debug which interfaces via JTAG/TRACE. Therefore, JTAG and trace will be the only debugging interfacing options for the AM263x. The debug subsystem is designed to provide the following debug features:

    • JTAG debug access to debug resources, mapped through an ARM SWJ-DP and TI ICEPickM scan module
    • System memory access without halting the processor
    • ETM-based trace for ARM R5F
    • Cross trigger to halt and restart cores and peripherals based on events such as watchdog, timers, DMA, and time-stamp events
    • capability to read the device ID data

    For more information, please refer to the On-Chip Debug chapter of the AM263x Technical Reference Manual.

    Please let me know if you have any further questions.

    Regards,

    Erik
