Tool/software:

Hello TI,

TI PDK for J784S4XEVM RTOS, (09.02.00.05) (dr-download.ti.com/.../psdk_rtos_ti_data_set_09_ 02_00.tar.gz ), descriptors for Ethernet DMA communication are located in the following bss segment

  • .bss:ENET_DMA_DESC_MEMPOOL
  • .bss:ENET_DMA_OBJ_MEM
  • .bss:ENET_DMA_PKT_INFO_MEMPOOL
  • .bss:ENET_DMA_PKT_MEMPOOL
  • .bss:ENET_DMA_RING_MEMPOOL

Please let me know the location and name of the scatter file so that I can know where these descriptors are located in the memory area and the attributes of that memory area.(I checked here as well, but could not find it)

    Hi,

    Please refer to the "pdk/packages/ti/drv/enet/examples/utils/enet_appmemutils.c" file for the memory utils of enet applications.
    Also, refer to the Linker file from "pdk_j784s4_09_02_00_30/packages/ti/drv/enet/examples/build/j784s4/linker_r5_freertos.lds" for the memory mapping to enet DMA and packet buffers.
    Also, refer to mpu configuration file from "pdk_j784s4_09_02_00_30/packages/ti/drv/enet/examples/build/j784s4/r5_mpu_default.c" for the memory attributes.

    Best Regards,
    Sudheer

    Hello TI,

    Thanks for the reply.

    I was able to check the descriptor settings for Ethernet.

    Thank you very much.
