ew_gui port to free rtos

vasudhevan — Thu, 23 Jan 2020 10:30:09 GMT

Hi,

Board = imxrt1064evk.

SDK = SDK_2.7.0_EVK-MIMXRT1064

I am trying to port ew_gui(ew_gui_bezier_clock) to free rtos.

I am getting error ew_gui ew_bsp_clock.c used systick handler and free rtos also using systick handler.

If i comment systick handler in ew_bsp_clock.c there is no error but only idle thread is running GuiThread(priority 5) is not running.

How to solve this issue ?

How to port ew_gui to free rtos ?

Thanks & Regards

Vasu

Hi,

I can able to port ew_gui demo to free rtos.

I have another issue multitasking is not working.

ew_gui ported to tcp_echo_free_rtos project if i run only tcp thread running fine and only ew_gui thread running fine.

If i run both threads only ew_gui running other threads not running.

How to solve this issue ?

Thanks & Regards

Hello Vasu,

Have you tried increasing the heap size of the project?

Hi Victor,

Thank you for your reply,

Heap size already increased but still same issue.

If i run ew_gui thread other network threads(mqtt,http) not running ethernet led(see IMG_20200203_091644) also not blinking and adc thread running with wrong value.

If i commend ew_gui threads other thread running fine mqtt,http server, etc..

Please give some suggestion.
