Shalom!
I have a custom nRF9160 board with uart0 connected to the outside world by RS232. I set the uart0 as the printk() debug output. I also need to write and read binary data through uart0.
When using the nRF9160-DK I was able to configure everything and it worked well through a single virtual com. If I turn off the printk() output I can use the uart without problems but I want to see the Zephyr and Nordic debug information that helps in problem solving.
Now on our custom board, I get to z_arm_secure_fault() when I try to set the callback by ret = uart_callback_set(uart_dev, uart_CB, (void *) &tx_aborted_count);.
What conf and overlay defines must I use to make this possible?
It seems that the system may already use a callback.
I set in my boardns.overlay
&uart0 {
status = "okay";
current-speed = <115200>;
tx-pin = <1>;
rx-pin = <0>;
};
I set in my boardns.conf file:
# UART CONFIG_SERIAL=y CONFIG_UART_ASYNC_API=y # Enable Async API CONFIG_UART_INTERRUPT_DRIVEN=y #Enable RTT Console for prints() CONFIG_USE_SEGGER_RTT=n CONFIG_RTT_CONSOLE=n # Enable UART console, for printk() CONFIG_UART_CONSOLE=y ?!? changed to n CONFIG_CONSOLE_HANDLER=n CONFIG_CONSOLE=y CONFIG_UART_CONSOLE=y # Async CONFIG_UART_0_ASYNC=y CONFIG_UART_0_NRF_HW_ASYNC=y CONFIG_UART_0_NRF_HW_ASYNC_TIMER=1 CONFIG_NRFX_TIMER=y CONFIG_NRFX_TIMER1=y # Trusted execution CONFIG_TRUSTED_EXECUTION_NONSECURE=y
In my board_common.dts file I have:
chosen {
zephyr,console = &uart0;
zephyr,shell-uart = &uart0;
zephyr,uart-mcumgr = &uart0;
};
&uart0 {
status = "okay";
current-speed = <115200>;
tx-pin = <1>;
rx-pin = <0>;
};
