Other Parts Discussed in Thread: TMS320F28022, TMS320F28335

Hi,  I keep getting this error when I try to start a debug session.  I'm using a Spectrum Digital XDS100V2.  Target is a TMS320F28022.

C28xx: Failed Software Reset: (Error -1137 @ 0x0) Device is held in reset. Take the device out of reset, and retry the operation. (Emulation package 5.0.747.0).

The test connection function works and passes.

    Tom,

    set the device to wait boot mode or SCI/PARALLEL boot mode before you connect to JTAG. Its probably trying to boot to flash and since you don;t have aything programmed yet in flash it is going through iTRAP and getting reset because of iTRAP handling in bootROM.

    Hi,

    I have a similar problem with the TMS320F28335 using the XDS100v2. I have the following error messages :

    This is the first time I'm trying to program the device. I don't understand why there is the first warning, because I'm sure the device is a TMS320F28335. Electrical levels on the JTAG are OK so it seems its connection is right. I have a pull-up on the XRS pin, but it gives me only 2.6 V (instead of 3.3V). Is 2.6V too low and it is consider as a low logic level giving a reset ?

    Best regards,

    Maxime,

    change the boot mode pins to let the device boot into wait boot mode or SCI/Parallel boot modes. Now connect CCS via JTAG and see how things work.by the way the below error message means you are using a wrong traget config for your device. Try selecting the proper device by editing the target config or creating a new target config.
