MQX RTOS for FRDM_K20D50M

[madagaskar]

Hello everyone!

I try using MQX RTOS to programing microcontroller from FRDM_K20D50M board (MK20DX128). I found information that TWR_K20D50M is fully supported by MQX. Does anybody know if FRDM-K20D50M board can cooperate witch full MQX RTOS to? Can I use OPENSDA to debug? Anyone tried it?

Hi Pawel,

Luis is correct.

A general rule of thumb is Freedom boards are supported with MQXLite and Tower boards with MQX.

Hello,

Yes, MQX will work on the K20 at 50Mhz. But as the harware is not the same, the bsp has to be modified, but many things can be reused. Have a look at this threat for BSP porting. You have the 'Clone' tool in the /tools MQX folder, you can start cloning the TWR-K20D50 BSP and make the modifications for the FRDM board. Internal peripherals drivers will be the same.

And yes, you can debug using OPENSDA.
