LAUNCHXL-F280049C: Failed unlocking device (zone 1) after reset

Part Number: LAUNCHXL-F280049C
Other Parts Discussed in Thread: DRV8311HEVM,

Hi,

I am trying to get the LAUNCHXL-F280049C working with the DRV8311HEVM board for motor control. I have tried using the DRV8311xEVM InstaSPIN Universal GUI, but despite running through all the board configuration & steps, the firmware fails to control the motor correctly.

So I am instead now trying to run through the univeral motorcontrol lab examples to adapt and build the firmware myself, so I should at least have debug access to see what is going on.

However, when I try to debug (and flash) my built application, I get the following error:

C28xx_CPU1: GEL Output:

RAM initialization done

C28xx_CPU1: Error occurred during flash operation: Unable to get file info from algorithm
C28xx_CPU1: Error occurred during flash operation: No algorithm has been loaded in which to look up "_exit"

It looks like the flash is locked some how, presumably by the firmware loaded by the DRV8311xEVM InstaSPIN Universal GUI?

Any idea how I can get this unlocked?

Thanks.
