DRA821U: About DRA821U R5F

Part Number: DRA821U


please see my posted picture.

I have read many documents about J7200.

J7200 has 4 R5F.

On the JTAG screen, there are 4 R5F, (MainR50_0 , MainR50_1, MCU_R5_0, MCU_R5_1).

May question is:

#1. What's the correct cmd for building each R5F?

      can you list the 4 commands for building each R5F here?

      What's the CCS load program R5F image format?

#2. When built out the R5 image, what's the procedure to put it onto the SD card?

      Do we need to convert the format?

      What's the location of the SD card path for putting the R5F image we build?

please comment.

    Rio, 

    I assume you are using the gmake or make command to build an application under pdk? if so, the list of cores supported are:

       mpu1_0 mcu1_0 mcu1_1 mcu2_0 mcu2_1 mpu1_1

    as you can see, the main domain R5 core names are specified as mcu2_0 and mcu2_1.  Once built, you application will have three different binary format, similar to the example screenshot below. you will use .xer5f if you directly load the core via CCS. It is the same as .out in ELF format. 

    On #2 for SD card set up, you my reference steps at:

        pdk_j7200_07_03_00_29/docs/userguide/j7200/boot/boot_k3.html#booting-via-sd-card

    let me know if you run into any issues. 

    regards
