MCU SDK Memory Footprints

Other Parts Discussed in Thread: SYSBIOS

Could anyone please descripe the MCU SDK Memory Footprints? How large is it? It looks like the size is too large to use in the real project.

    Hello,

    I am going to move this thread to the BIOS forum for the experts there.

    Thank you

    Lori

    Hi Jeanne --

    Which peripherals do you require for your application?  

    What is your memory budget?

    We were able to build a demo app that used SYS/BIOS, USB, NDK, UART, I2C and the FAT filesystem using SD card on a Concerto EVM.

    Attached are some slides with rough memory usage.

    We are working on providing better benchmarks for the assorted peripherals in a future release of the SDK.

    Regards,

    Karl,

    Thanks a lot for your kind reply!

    I will use 4 GPIO, 3 UART and EPI peripherals, IPC as well.

    If I use the drivers within the MCU SDK, I'm not sure how much flash rom will be occupied. My team member prefer to write the drivers by ourselves to reserve the flash room for the application. But I'm a newer to use the SYSBIOS, do you think it's reasonable to write the driver instead of using the one within the MCU SDK? Do you have any suggestion to customize  the size as minimal as possible?

    Thanks!
