Yes a little because I got error “undefined reference to ''__device_dts_ord_84” so I commended out the below code in setup_uart() and disabled the UART in dev tree. With NFED I think you mean nrf sdk version? That is V2.6.1.
`
static const struct device *const console_dev = DEVICE_DT_GET(DT_CHOSEN(zephyr_console));
/* Disable console UART */
int err = pm_device_action_run(console_dev, PM_DEVICE_ACTION_SUSPEND);
if (err < 0)
{
printk("Unable to suspend console UART. (err: %d)\n", err);
return err;
}
