I want to move the UART on thingy91:nRF9160.
prj_thingy91_nrf9160ns.conf added the following two line.
CONFIG_UART_ASYNC_API=y
CONFIG_NRFX_UARTE0=y
The asset_tracker added to the main function of the sample as follows.
/* Initialize the UART module */
uart_dev = device_get_binding(DT_LABEL(DT_NODELABEL(uart0)));
if (uart_dev == NULL) {
LOG_ERR("Cannot bind UART device\n");
return -EINVAL;
}
err = uart_callback_set(uart_dev, uart_cb, NULL);
if (err) {
LOG_ERR("Cannot set callback: %d", err);
return -EFAULT;
}
The callback uart_cb a function that does nothing.
static void uart_cb(const struct device *dev, struct uart_event *evt, void *user_data)
{}
If you do this, booting will repeat infinitely.

uart_callback_set a comment that is calling for a comment, it will move.

What causes it not to move?
