Tool/software: Code Composer Studio

Hi,

The program crash after the breakpoint.

I find that the program run ok when I do not configure the Wait1 pin.So I suspect the crash has something to do with the Wait1 pin.

I have two doubts.

1,What causes this problem(Can't Single Step Target Program: (Error -2062 @ 0x1FE) Unable to halt device.) ?

2,It caused the crash because the AM335x did not wait the Wait1 signal. Is it possible ?

    Hi,

    Yes, it is possible, it looks that you used the wait1 pin for GPMC read access. Please look at the AM3358 TRM, 7.1.2.3.8.3 External Signals:

    • WAIT Pin Monitoring Control
    • A-SYNC/SYNC read access

    If your configurations violate this.

    Regards, Eric
