SDK: qca4020-or-3-5_qca_oem_sdk-cdb

I can build all the demo application and also flash using "flash_openocd.sh". But after removing the jumper J31 1&2, and power cycle the CDB didn't come up.   

I appreciate help to debug what's wrong with the setup. 

Here are the few lines of flash output:

./flash_openocd.sh

The demo application works as expected when the apps built with SDK:qca4020-or-3-4_qca_oem_sdk-cdb.

Assume you are using python 3 to build and "build.bat f 4020 cdb" command resulted in successful compilation and linking.
There shouldnt be any issue if the valid image is flashed on CDB device.

Can you try switch to Helloworld_Demo and check the behaviour ?
