Processed Binaries Directory Structure

The create_bsp tools take the -g argument to specify the output directory path where processed binaries are generated. After executing create_bsp tool, a per SKU-based directory is created under the output directory.

For example, if create_bsp is executed to create binaries for a board, the board.json file is used to set board unique variables. The f_SignedCustomerData variable is used to specify static signed customer data. An example:

board = p3710-10-s05

In platform-config/hardware/nvidia/platform/t23x/automotive/flashing/board_configs, you see the file p3710-10-s05.json. Inside this file:

"f_SignedCustomerData":"p3710-10-ts5_signed_customer_data.json",

The contents are:

{
        "customer-data-signed": {
                "skuNumber": {"version": 1, "value": "642-63710-0010-000"},
                "skuVersion": "TS5",
                "sysBomInfo": "000-0000-0000-000 00",
                "prodInfo": "940-63710-0010",
                "boardName": "p3710-10-s05",
                "socSkuVersion": "F0-A1"
        }
}

Inside the directory specified by -g, there are the subdirectories:

642-63710-0010-000_TS5  firmware  tools

The 642-63710-0010-000_TS5 directory is formed by concatenating skunumber_skuVersion.

Under the sub-directory, four sets of binaries are generated as flash-images,

rcm-boot, rcm-flash, and
         rcm-flash-provision.

ls p3710-10-s05/642-63710-0010-000_TS5/
flash-images  rcm-boot  rcm-flash  rcm-flash-provision  TargetInfo.txt  ToolsVersion.txt

Add a new row to the table for the new sub-directory:

Sub-directory              Description  
... 
rcm-flash-provision     Binaries needed to reprovision the Ufs

The generated sub-directories are as follows:


Sub-directory	Description
flash-images	Contains processed binaries flashed on the target storage medium. Also contains FileToFlash.txt, a summary file that contains information about binary names to flash at offsets for the final target flash structure. These binaries are used for the update tool update_sample.
rcm-boot	Contains the necessary binaries to boot the target without writing binaries to the medium.
rcm-flash	Contains binaries similar to rcm-boot for booting the Linux kernel on initramfs without writing binaries to the medium. These binaries are generated from a set of prebuilt binaries that are used for flashing.
