Low Power Mode

Other Parts Discussed in Thread: TMS320F28027, TMS320F28377D

I have been trying to connect to a custom TMS320F28027.  I get this error

"Failed Software Reset: A reset is already in progress:

(Error -1156 @ 0x0)
Device may be operating in low-power mode. Do you want to bring it out of this mode?
(Emulation package 5.1.8.0)"

I have a pull up resistor on the XRS pin to try to pull it out of reset.  Please help if you can.

    Hello,

    Have you scoped the XRSn pin to see if indeed it is 3.3V?  Also scope all of the power pins to confirm that the required voltage is being supplied.

    Regards,

    Hello Adam,

    Whether the bad flash(on chip) or lock the flash may lead to this issue?

    Roc,

    Which device are you using?

    Is the device on a controlcard, TI kit or custom PCB?

    How are you powering the device?

    If you are programming to flash, this could be caused by not supplying enough current to program the flash.  

    Regards,

    Adam

    Hi Mubin Qadri

    I had similar problems with 28377D controlCard. (The problems arised when I was playing with PLL settings...)

    I was able to solve my problem by erasing the whole flash like this:

    (if question about low power mode comes -> click yes)

    • View ->Target configurations
    • Right click on target config -> launch selected configuration
    • In Debug perspective -> Menu Run -> Connect Target
    • Then setting a breakpoint at 0x80000 (in disassembly view)
    • Free run until breakpoint is hit
    • Menu Tools -> On-Chip Flash -> Erase entire flash
    • After erasing -> Stop debug -> cycle power of board

    After this procedure I was able to connect "normally" whith debugger.
