MKE04Z8VFK4 SDK overflow the program memory

jingtian_li — Tue, 31 Dec 2019 14:45:03 GMT

Hello,

I tried to use the MKE04Z8VFK4 for build a project but the console showed the program memory was overflowed, the interesting thing was my project was empty, it contained nothing but pins and devices definitions.

So I created the new one which imported the examples (HelloWorld, UART_interrupt, UART_polling) of the SDK to see how they would be, they still showed the memory overflow, from 128%-140%.

Finally I created a empty project without any definitions but SDK, it still used 89.26% of program flash.

Anyone know how to reduce the size of the SDK significantly? Or the other ways which I can make the chip works? 10.74% is definitely not enough if I want to use the features of the chip.

My MCUXpresso is 11.1.0. SDK version 2.7.0 (Stage 736), Manifest Version 3.6.0. Config Tools 7.0.0

Thanks

Hi jingtian,

printf occupies most of the code space. Please refer to Reduce source code size for Kinetis Series MKL03

If space is still not enough, you can upgrade the compile optimize level. https://community.nxp.com/message/1053737?commentID=1053737#comment-1053737

Regards,

Jing
