Unable to erase flash on F28069 ControlCard/Usb Dock

Other Parts Discussed in Thread: CONTROLSUITE, UNIFLASH

Hi,

I am getting an error when trying to erase any flash section using the "On-Chip Flash" tool in CCS 5.3. it looks like this

C28xx: Erasing Flash memory...
C28xx: Erasing Flash Sector A
C28xx: Flash Programmer: Error erasing flash memory. Error erasing Sector A

Loading anything (code or data) on to the flash creates similar error.

C28xx: Writing Flash @ Address 0x003F452D of Length 0x00000016
C28xx: Finish Writing Flash @ Address 0x003F452D of Length 0x00000016
C28xx: Writing Flash @ Address 0x003F4000 of Length 0x0000052D
C28xx: Flash Programmer: Error encountered when writing to flash memory
C28xx: Error Writing Flash @ Address 0x003F4000 of Length 0x0000052D
C28xx: GEL: File: C:\ti\controlSUITE\development_kits\TemplateProjects\FlashingLeds-F28069_v1.0\F2806x_FLASH\FlashingLeds.out: Load failed.

The same program runs fine from RAM.

What could be wrong? Thanks

Hello!

Perhaps you have incorrectly set the target device at "On-Chip Flash" tool.

Thanks for reply but I don't see where I get to set target device in the "On-Chip Flash". I am able to debug programs that run from RAM so I suppose my target configuration is fine.

Hello!

It seems everything is right at your screenshot. I work with CCSv5.2.

Run->Debug Configurations->main:

Run->Debug Configurations->target:

And what about OSCCLK? Maybe the external crystal (not 10 MHz) is used in your board? Do you apply Flash.CMD instead RAM.CMD?

Igor

I am using the F28069 Experimenter Kit so I don't think it runs off an external clock or crystal. The RAM.CMD works fine, but FLASH.CMD creates the error mentioned earlier.

Thanks

After thinking something went wrong at the Flash process, I'm convinced the error is another. The CSM password could be read, when debugging with a RAM-Linkerfile. The Screenshot shows the situation.

Hi Dan!

Try to go through this thread http://e2e.ti.com/support/microcontrollers/c2000/f/171/p/293372/1024794.aspx#1024794

Hi Yan,

Did you try running the flash example meant for F28069?

Also, please try with CCS Uniflash.

Nope,

it's an F28335 on a Control Card put into a slot of a self developed hardwareboard, which runs in another project without any problems.

The Example I use is the F28335_examples_CCSv5 (nonBIOS) in combination with the Library V.210.

I tried to use Uniflash as well, but the same error occurs. The device seems to be unlocked, but I can't delete sector A. The Clock settings are correct: 150 MHz-> 30Q * 10 / 2.

I can't finish the depletion tool successfull, too. Is my µ destroyed or can I save it?

Regards

Dan

Dan, before concluding anything, I would like you to check with the attached project:

1323.flash_f28335.zip

Also use the Unlock feature in CCS Uniflash before programming.

Gautam

Hi Gautam

Thank you for your help.

In the above picture you can see, that I tried Uniflash and failed. I can't try the example, because I can't enter the Flash. When I start the debugger, CCS tries to erase the whole Flash Memory and an error occurs. I can start the debugger only, when I start the program from RAM.

Best regards

Dan

So, it wouldn't be wrong if we conclude that flash memory of your device has been bricked :(

The above statement would be true if and only if you're 100% sure that cmd file has been properly configured.

Gautam
