program F28069 flash with uniflash

Other Parts Discussed in Thread: UNIFLASH, CONTROLSUITE

Can someone explain how to load a program using uniflash? Seems like it should be simple but I can't get it to work...

I'm using uniflash v 3.4 and the F28069 experimenters kit (controlCARD with docking station).

I can run the LED blink example from CCS v6 successfully. Now I want to program the flash using uniflash. So I setup a new configuration using the Texas Instruments XDS100v1 USB Debug Probe as the connection and Experimenter's Kit - Piccolo F28069. I add the .out file from the example project in the programs window of uniflash and hit program. It says loading program and then operations finished but the program doesn't run afterwards or after power cycle. If I hit verify I get:

ERROR >> C28xx: File Loader: Verification failed: Values at address 0x0000000000000000 do not match Please verify target memory and memory map.

File: C:\ti\controlSUITE\device_support\f2806x\v150\F2806x_examples_ccsv5\timed_led_blink\Debug\Example_2806xLEDBlink.out: a data verification error occurred, file load failed.

How do I get it working?

Hi,

Are you sure the blink code is designed to be written in Flash? The reason is that not only the address where the error occurs is mapped to RAM but also the Uniflash may reset the target after loading the code, thus probably causing the code to not properly run after programming.

I would try to get a flash-based example code and see if that works.

Hope this helps,

Hello,
That is odd. If you can get it to work in CCS, it should load fine with Uniflash. Can you zip and attach to this thread the out file you are trying to program?

Thanks

Thanks for replying. When you program through CCS it programs the flash right, so the .out should be designed to be written to flash? I'm not sure how to tell if the blink code is designed to be written in flash. How can I tell? I've attached the .out file.

Are you using the default (unmodified) Example_2806xLEDBlink example from ControlSUITE? That one uses the 28069_RAM_link.cmd file which puts the code in RAML0-3

Yes, I am using Example_2806xLEDBlink.

Ok so I see that in the properties for Example_2806xLEDBlink the linker command file is 28069_RAM_lnk.cmd. Seems like I should be using some flash linker command file? I don't see one that says flash specifically for 28069 but there is a F28069.cmd file. How do I set the example to put code in flash?

Try using the stock "F28069.cmd" file (it should show up in the dropdown list). That will allocate the code into into FLASHA

Changing the Linker Command File in properties to F28069.cmd made it possible for me to program the flash via uniflash. I had to power cycle the device after programming in uniflash. Thanks for your help Ki-Soo!
