I switched to v0.4.0 and it is working now. Thanks for your support.

I would recommend upgrading to v0.4.0. That said, did you change the uart2 pins in secure boot v0.3.0 nrf9160_pca10090.overlay ?

HI,

I am building fnrf9160_pca10090 which is the only board available in my SDK as I am using v0.3.0 tag. I had some difficulties importing project when I used v0.4.0 tag, and I already had v0.3.0 setup so I just kept using that.

I did not make any changes to prj.conf and CONFIG_TRUSTED_EXECUTION_NONSECURE=y.

I am using secure boot project instead of spm which is the option in v0.3.0. I did reload the secure boot to make the changes effective for UART0 there too.

Hi,

Are you building for target nrf9160_pca10090 or nrf9160_pca10090ns ?

Are you on the v0.4.0 tag ?

Did you make any changes to prj.conf ? Is CONFIG_TRUSTED_EXECUTION_NONSECURE set to n or y ?

Since spm(previously called “secure boot”) also uses UART0, you might need set the overlay for the spm project for the changes to take effect. I.e. add the uart0 changes to the nrf9160_pca10090.overlay in folder \ncs\nrf\samples\nrf9160\spm
