CCS/TMS320F28069: Error encountered when writing to flash memory

just wondering :
before I used the TMS320F28069PZPS – with Success

Now I try to program the TMS320F28069UPZPS – but I do not succeed

any differences between theses 2 versions that don't allow me to use the XDS100?

your answer is very appreciated
Thanks
Hamid

Hamid, both device should be same from CCS connection and code loading point of view. Please check if you have installed all the CCS updates. You can check the same by clicking on "Help" -> "Check for Updates" and install any update available for C2000.

Thank you Vivek for your fast answer
I figured out that TMS320F28069UPZPS has USB andd TMS320F28069PZPS not and that has nothing to do with my problem.
Regarding the update I downloaded the last version of the UNIFLASH and I can't even erase the flash memory or calculate the checksum but I can read
Hamid

I also install all the updates available for c2000 but I still having the same problem:
[ERROR] C28xx: Error occurred during flash operation: Timed out waiting for target to halt while executing FlashAPIInterface2806xV1_00.out
[ERROR] C28xx: Flash Programmer: Error erasing flash memory. Flash operation timed out waiting for the algorithm to complete. Operation cancelled.

Instead of Uniflash, can you try CCS?

I tried first with CCS and is the same behave

Hi Vivek,
I just found that the xrs pin goes low every 13.4ms milliseconds when I launch the erase or program tools and stays high after. Is that normal ?
is it important to add a capacitor (100nf) at this pin ?
Thanks
Hamid

Hamid,

You should follow the guidelines provide in device manual. Toggling XRSn is not good and could cause issue with connection. It may be because of BOOT MODE pin setting. Please check of BOOT MODE pin setting is same on working and non-working boards.

Hi Viivek,

Yes I am following the guidelines provided in the manual. The pin XRS is tied to vdd through 2.2k   but I didn't put any capacitor   and I did the same thing for another board athat I was able to load the program on it.

regarding the boot mode   , when the emulator is connected the pin TRST is set to high level  so  the selected mode is "Emulation Boot"    regardless of the  state of  other pins.

when I connect the emulator  the pin XRS  doesn't toggle.  Only when I start the erasing or  the programming   functions   XRS start toggling  and stop when the functions end with error.

any idea what can cause this problem ?

Thanks

Hi Viivek,

I configured GPIO34 and GPiO37  to work in wait mode at power up , I am no able to erase flash , to read memory  but I still not able to load the program
