MCU-PLUS-SDK-AM273X: LWIP driver and stack size

Part Number: MCU-PLUS-SDK-AM273X

Hi expert,

From the post https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1083645/mcu-plus-sdk-am243x-lwip-stack-code-data-size/4014600

It was said LWIP will be optimized to 200KB on AM243x SDK. Is it also supported on AM273x MCU SDK? If yes, when TI could release the optimized MCU SDK?

Thank you.

Regards,

Allen

  • Hi Allen,

    With latest SDK8.3, we have optimized the Ethernet and LwIP driver even on the AM273x as well. We can fit LwIP & Enet driver in <200KB with memory optimized version.

    Please note the default SDK example is optimized for the performance hence higher memory allocated for data memory. You can build the Enet lwip application and confirm the memory consumption through map file. 

    gmake -sj -C examples/networking/lwip/enet_lwip_cpsw/am273x-evm/r5fss0-0_freertos/ti-arm-clang all
