TMS320F280023: The UniFlash could not Erase and Write the TMS320F280023, but could only read.

Part Number: TMS320F280023
Other Parts Discussed in Thread: UNIFLASH

Hi Ti C2000 team,

I have the following questions:

1. I try to use the UniFlash to download our code, but it report error. 

2. I also use the ccs to debug with TI's demo code, it stops in the  infinite loop of function PollX1Counter(), which was in the InitSysCtrl() function.

3. the document "migration between TMS320F28004X and TMS320F28002X"  mentioned that TMS320F28002X did not contain the DC-DC, so for TMS320F28002X, should the VDD pin be supplied with an external 1.2V regulator.

thanks a lot

Luke

Best Regards

    Luke,

    #1. This does not seem to me like a Uniflash (flash programming) issue.

    Please review http://www.ti.com/lit/spracf0 and see if that helps to resolve the issue.  You may also want to try the flash operations after configuring the boot mode GPIOs for wait boot option.  

    For the remaining questions, I will assign this post to our clock/PLL expert.

    Thanks and regards,
    Vamsi

    Hi Vamsi,

    1. the issue of the Uniflash programming solved, the Voltage of the VDDIO  lower than 3.0V, I just improve the voltage, now the flash could be erase and program by the Uniflash.

    2. the clock/PLL in CCS has not been solved, i would also check the project setting.

    thanks a lot

    Luke

    Best Regards
