Can't flash CC3220 with OpenOCD

[Andreasdahlberg]

Describe the bug
I tried flashing the hello world sample application but the flash command returns an error(see console output) and the application is not loaded onto the board.

I have also tried loading the bin-file using UniFlash with no success. UniFlash does not report any errors but the application does not appear to be running(not console output at all).

To Reproduce
Steps to reproduce the behavior:

1. mkdir build; cd build
2. cmake -GNinja -DBOARD=cc3220sf_launchxl ..
3. ninja flash
4. See error

Expected behavior
I expect the hello world application to be loaded into flash.

Impact
Showstopper since i can't test any applications on target.

Screenshots or console output

Additional context
I have put the board into “Development Mode” using UniFlash and jumper SOP(j15) is set to [001].

I have also checked that CONFIG_XIP=y is set.

@Andreasdahlberg Which version of openocd are you using?

I am working on Ubuntu 18.04 and am on the latest commit (46a2181dbc2d5dc8fa800ca519efc4377a44e9c5) of the 'develop' branch, and can confirm that 'ninja flash' works for me:

If you had tried to use Uniflash to flash the .bin file, please first revert by removing the MCU
Image (.bin) file from Uniflash and reflashing the device with just the other files, as per step 3 in the Prerequisites section in https://docs.zephyrproject.org/latest/boards/arm/cc3220sf_launchxl/doc/cc3220sf_launchxl.html. Then go back to running 'ninja flash' and see if it helps.

Best regards,
Vincent

[Andreasdahlberg]

It's working now, i tried your suggestion about reflashing the device without the MCU Image and it solved the issue.

Thank you for the help!

Best regards,
Andreas
