twr-k60 freertos demo does not work

[tirak]

Hi,

I'm new here. Maybe someone can help me.

I have the TWR-K60 Board and downloaded the SDK with FreeRTOS support.

I selected the lwip_tcpecho_demo_freertos demo. But to my suprise I cannot compile it.

Everything is fresh installed. I'm confused as I don't believe that NXP would offer a demo to the whole community that doesn't work.

It seems it doesn't use the lower RAM. What is wrong here?

Ok, this works. Thanx Daniel.

Another thing... as I figured out that the most Kinetis EVAL-Boards are fitted with a KXXFN CPU there is no EEPROM via FlexRAM possible. As I understood only with FX CPUs.

I want port code from a Atmel CPU to an Kinetis. But I need to store user config data. The Atmel has EEPROM which I use for it. I don't want to build hardware for testing it.
Is it somehow possible to store user data without having this 4k FlexRAM?

My TWR-K60DN512 doesn't support EEPROM via FlexRAM if I understood right.

I used the SDK Builder on the Web-Site similar to the description in the followed link:
Generating a downloadable MCUXpresso SDK v.2 package 

There you can select FreeRTOS

Than I downloaded it and simply drag and drop it to the project.
Then it offers you both, bm and FreeRTOS in the demo selections. But FreeRTOS doesn't work.

Hi Marcus:

I would suggest you put the global data to SRAM_LOWER. Please refer to below picture.

Could you please let me know your SDK version and the IDE version?

Could you download the latest sdk from Welcome | MCUXpresso SDK Builder   and try it again?

Hi Marcus:

From MCUXpresso IDE, only lwip_tcpecho bm demo can be imported in my side. How can you import the freertos version?
