K64F FreeRTOS USB device CDC

davenadler — Sun, 25 Sep 2016 19:58:42 GMT

I'm starting an evaluation of K64F using the Freeedom board.
Need to build a project using FreeRTOS and including:

USB OTG, initially supporting device-mode CDC
TCP/IP and Telnet or SSH
later, USB host mode supporting MSD (memory stick for logging, and bootloader SW updates)

A pretty common set of requirements for many of our customers and projects...

Unfortunately the "Project Generator" doesn't display the project names so I cannot read the list
(dope-slap to whomever did the GUI here - see below for too-small drop-down list without horizontal scroll).

What is the best example project to start with to quickly get the above functionality in place?
And how can I find it in this incompletely-displayed list?

Thanks in advance,
Best Regards, Dave

Hi Dave,

First of all, there is no such complex example. Also there is no Telnet example fo KSDK 2.0.

Under older KSDK for MQX

C:\Freescale\KSDK_1.3.0\middleware\tcpip\rtcs\examples\shell

We have separate examples, which you will find under

C:\Freescale\SDK_2.0_FRDM-K64F\boards\frdmk64f

there are also usb examples and lwip.

C:\Freescale\SDK_2.0_FRDM-K64F\boards\frdmk64f\usb_examples

C:\Freescale\SDK_2.0_FRDM-K64F\boards\frdmk64f\demo_apps\lwip

and needed documentation

C:\Freescale\SDK_2.0_FRDM-K64F_original\docs

The best way is start with some of USB demo and build up your code on this demo (add lwip etc).

At the moment there is newer GUI for Project Generator, v.2.3

Please see https://community.nxp.com/message/841733

I very apologize for the late response.

I hope this helps you.

Best Regards,

Iva

Hello Iva,

I am using FRDM K64F, and cloned the example in KDS_v3. But I saw, there was an issue for initiation USB's pins. For this example, I didn't see setting USB's pins. Only defined UART0's pins following code:

PORT_SetPinMux(PORTB, PIN16_IDX, kPORT_MuxAlt3); /* PORTB16 (pin 62) is configured as UART0_RX */

PORT_SetPinMux(PORTB, PIN17_IDX, kPORT_MuxAlt3); /* PORTB17 (pin 63) is configured as UART0_TX */

Regards,
