TMS320F28015: Issues Connecting TMS320F28015 with XDS110 in UniFlash and CCS 12

Part Number: TMS320F28015
Other Parts Discussed in Thread: UNIFLASH,

Tool/software:

Hello everyone,

I'm using a Texas Instruments XDS110 USB Debug Probe with UniFlash (Version: 8.6.0.4688) to connect to a TMS320F28015 device. However, I'm encountering an issue where UniFlash reports that the "device is in low power mode" and fails to connect.

Interestingly, when I use the Flash Pro 2000 to connect to the same TMS320F28015 device, it connects successfully. I'm wondering if there's a specific setting or modification I need to make in UniFlash to resolve this issue?

Additionally, I'm also having trouble in Code Composer Studio 12 when trying to use the XDS110. The error I get is "IR and DR is invalidated."

Has anyone encountered similar problems or have any suggestions on how to fix these issues?

Thank you in advance for your help!

Best regards,
Mario

  • Hi,

    Could you take a look at this app note? Could you share a screenshot of you  "IR and DR is invalidated" message? Is that the same message you see if you Test Connection as mentioned in the app note?

  • Hi Mario,

    Could you please follow the debug steps in the app note for this error message?

  • Hi

    how can i set device to wait-boot mode?

    I have looked through the "TMS320F280x, TMS320C280x, TMS320F2801x Digital Signal Processors Datasheet (Rev. P)" but did not find the information.

    Thanks

    Mario

  • Any boot mode except boot to flash can be used instead.
