TMDXEVM6678L reset from command line

Jorge A
Prodigy 20 points

I'm using an XDS560v2 Emulator connected to a TMDXEVM6678L board.

Sometimes my board gets into a strange state and I must power cycle it manually in order for the emulator to connect.  Is there any way to perform this power cycle using the emulator (i.e. "hard" reset)?  I'm looking to script this reset and avoid any manual button pressing.

    Dear Jorge,
    You can use "RSTCTRL" register to perform the RESET, you can do this programming with gel script.

    Jorge A,

    Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages (for processor issues). Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics (e2e.ti.com). Please read all the links below my signature.

    Note: We strongly recommend you to create new e2e thread for your queries instead of following up on an old/closed e2e thread, new threads gets more attention than old threads and can provide link of old threads or information on the new post for clarity and faster response.

    Jorge,

    What is the boot mode used? If you are running application on "No boot" mode using CCS and emulator, you should be able to reset using the CCS menu itself.

    Thank you.

    Raja, Thank you for this link.

    I am trying to recover from a state where I can't connect to the DSP via emulator so I think any reset requiring the toggling of registers won't work. Also, I'd like to perform the reset without any manual work (e.g. clicking in CCS). I found at the bottom of your link some information on the "dbgjtag" tool and how it can be used to drive the nRESET line, which I think is available on this board. I'm going to investigate this tool to see if it will work for me.

    Thanks!
    Jorge
