Fail to Porting Emwin into i.MX RT

li-chinwang — Thu, 15 Mar 2018 02:17:07 GMT

I porting emwin speedometer into i.MX RT and choose booting from external QSPI.

I always get the space not enough information like these.

I double it is problem of scatter file.

I saw emwin demo's scatter in lpc54608 is like this following.

Which way I need to modify scatter file to make it workable

How about I solve this problem.

sdram_debug\emwin_gui_demo.out: Error: L6406E: No space in execution regions with .ANY selector matching heap_4.o(.bss).

Hi,

There are emWin examples as part of the i.MX RT MCUXpresso SDK. Please refer to the following link to generate the proper SDK package according with the desired features/used IDE:

https://mcuxpresso.nxp.com/en/select

In case of having specific emWin issues, you could directly contact Segger:

https://www.segger.com/products/user-interface/emwin/

Hope this will be useful for you.
Best regards!
/Carlos
