TMS320F28035: Use Uniflash to unlock CSM and program again with one click

Part Number: TMS320F28035
Other Parts Discussed in Thread: UNIFLASH

Dear Champs,

I am asking this for our customer.

The user used to use C2000-GANG.

But because there is something wrong with C2000-GANG now (it's being dealt with), the user asked TI to have a backup solution using XDS110 + Uniflash.

The user uses CSM.

In the production line, it's required to update code (that is, the image on F28035 is already with CSM) sometimes.

In C2000-GANG, the user needs only to setup a correct CSM password for the first time on its GUI and it can be used to update FW code even if there is already a secured image.

Can Uniflash be used in this way?

That is, to setup a correct CSM password for the first time and then use it to program C2000 device with one click no matter its flash is empty or already with a secured image?

If yes, would you please show us how to do it?

If not, would you please add this function?

Hi Wayne,

This is assigned to me now.

In UniFlash GUI, there should be a provision to enter the passwords and an "unlock" button to unlock. Also a button "Remember My settings" is available so that the setting can be used to program any number of units later.

If I understand your question, you are asking whether or not it is needed to use the "unlock" button.

Did I understand your question correctly?

Thanks and regards,
Vamsi

Dear Vamsi,

The user wants to setup the password on GUI for the first time and then update images by only clicking "load image" to program the image directly including CSM unlocking, flash erase and flash programming.

They don't want to use unlock.

Is it possible?

Hi Wayne,

Uniflash also reads from the GUI and unlocks the device before program load if it finds that the device is locked.

Thanks and regards,

Vamsi,

I have another question, if the image(.out or .hex) added to uniflash is not locked(without password), then users need to use GUI, enter password and then press Program Password button to program security keys.

Is there any method uniflash reads from GUI and program passwords automatically, means that uniflash programs that non-password image and CSM passwords in one time when users press Load Image button?

Regards,

Luke

Luke,

Uniflash does not do that.

Thanks and regards,
