Hi,

I need some clarification regarding NXP mk22fn series micro-controller

1. Whether CLI (Command line interface/frame work) available for testing of interface like uart,i2c,spi,can,etc..

2. Whether this MCU support RTOS ?

3. Whether U-boot gives diagnostics for testing ?

or menu selection to see the boot console ?

Regards,

Hi, Ajay,

Q1. Whether CLI (Command line interface/frame work) available for testing of interface like uart,i2c,spi,can,etc..?

I suppose that you want to communicate with PC via interface like uart,i2c,spi,can,etc, this is case by case.

UART: as you know that RS232 transceiver and RS232 connector are required, you can use Hyperterminal or the other tools to communicate with PC.

CAN:there is USB-CAN device(third party board), you can insert the board via USB port of PC, with the tools the USB-CAN device manufacturer provides, you can send/receive CAN package via firmware in Kinstis. But the CAN transceiver is also required.

I2C or SPI: maybe there are device on market, i am not sure.

Q2. Whether this MCU support RTOS ?

Yes, MK22 support freeRTOS os, we have developed SDK package for MK22, the package includes FREERTOS os, you can create task based on freeRtos and switch task based on os mechanism.

Q3. Whether U-boot gives diagnostics for testing ?                 or menu selection to see the boot console ?

There is not U-boot, but the MK22 supports bootloader from uart,can..., the boot message can display on uart on PC.

Hope it can help you
