Hello,
I'm using the nRF Connect SDK v1.9.0 and a nRF5340 on a custom board.
I want to use MCUBoot as a primary bootloader. On the development kit, the UART connecting the nRF5340 and the interface IC is UART_0. There the project central_bas worked fine.
Now I have a board were UART_0 from the nRF5340 is connected to another IC, and I only have access to UART_1 over some pin header.
Is it possible to route the input and output that MCUBoot and e.g. mcumgr usually send via UART_0 over UART_1?
I tried to set a <BOARD>.overlay file:
/ {
chosen {
zephyr,console = &uart1;
zephyr,shell-uart = &uart1;
zephyr,uart-mcumgr = &uart1;
};
};
But this fails in linking with "undefined reference to uart1"
In the device.h file it says: If you get an error that looks like <tt>undefined reference to __device_dts_ord_<N></tt>, that is what happened. Check to make sure your device driver is being compiled, usually by enabling the Kconfig options it requires.
/** * @def DEVICE_DT_GET * * @brief Get a <tt>const struct device*</tt> from a devicetree node * identifier * * @details Returns a pointer to a device object created from a * devicetree node, if any device was allocated by a driver. * * If no such device was allocated, this will fail at linker time.

What Kconfig is required to use UART_1 in this case?
Best regards,
Alex
