TMS320F28335: TMS320F28335

Part Number: TMS320F28335
Other Parts Discussed in Thread: UNIFLASH

I have designed a controller board using TI 28335 IC . I am trying to program it for the first time. I am generating and out file and then flashing it through UNI FLASH software. Following error is occurring. What could be the reason?

    The error messages are saying how the target device can't be halted, thus indicating it is running out of control.

    Given this is a custom board, I would certainly debug the hardware. During the programming, check if the device supply voltage is constant, if there are no significant noise or spikes, if there are no inadvertent reset assertions (typically asserted low).

    If all seems ok, check if you need to issue a reset before loading the code. In the screenshot above, the section Reset Actions queries the device for the available reset options. This may help leave the device at a stable status before loading the code. 

    For a more featured troubleshooting, you can run the dbgjtag command: 

    C:\ti\uniflash_5.1.0\deskdb\content\TICloudAgent\win\ccs_base\common\uscif>dbgjtag -f @xds100v2 -rv -S integrity -S pathlength

    If it throws an error, search for it at the Debugging JTAG page at:

    https://software-dl.ti.com/ccs/esd/documents/ccs_debugging_jtag_connectivity_issues.html 

    Hope this helps,

  • Hardware I have checked as such I didn't find any error. Is it that we have to do some memory allocation in the beginning? Elese I would try debugging my JTAG connection again.

  • Hi,

    Not necessarily a memory allocation, but the F28335 development kit I have here requires boot mode jumpers to be set appropriately for the device to properly work. Check table 6-1 of the device's datasheet for additional clarifications.
