I am evaluating the KV46 MCU by using the HVP-K46F150M evaluation board. I tested all demo applications to understand how the various components could help us.
Today I have tried to run the freertos_queue example but I faced the first problem when I have built the example. The linker was not able to resolve some symbols. The project was configured to use REDLIB semihost. I modified the project settings to use the NEWLIB semihost and the linker was able to resolve all symbols. So I have tried to run the application in Debug from MCUXpresso and I have got the follow Confirm dialog box:
Device is secure. Erase to unsecure? WARNING: All information on this device will be erased. This inlcudes any pre-programmed libraries that may have been stored in a Flash Access Controlled (FAC) region (such as motor control library)
Since I am planning to use the motor control library I did not confirm to erase the flash.
What can I do to unsecure the device without erasing the motor control library?
Description of my setup:
* MCUXpresso with SDK 2.5.0 on MacOSX 10.14
* HVP-KV46F150M connected via USB to MacOSX
