lte_lc_connect() function error

[vchhabra]

Calling the lte_lc_connect() function eventually leads to the code breaking on:

fault_s.S line 104

#elif defined(CONFIG_ARMV7_M_ARMV8_M_MAINLINE)
    /* force unlock interrupts */
    eors.n r0, r0
    msr BASEPRI, r0

It never connects to the LTE tower. I am not using the nrf9160 board but a custom board config.

My question would be if there are any config settings which might cause the LTE to not connect?

The Issue was something to do with SPI0 and UART0 both being active and used at the same time in the project. When the code reached the connect function it probably could not resolve it and threw the fault.
