Query regarding split command #28

Open

Description

@Sriram-JI

Hi,
We have been using bootgen for a while, need to split the boot images as 3 partitions ( 1st partition -> FSBL - Uboot; 2nd partition -> Linux Kernel; 3rd partition -> RootFS).

Can we authenticate all partitions via eFUSE keys after being splited into three partitions??

Thanks,
Sriram

    Hi @Sriram-JI, could you please elaborate a little? Do you mean splitting into different boot images?
    If the question is regarding the split command available, it works as below:
    Slave boot mode splits as below.
    1. Boot Header + Bootloader
    2. Image and Partition Headers
    3. Rest of the partitions.
    Normal mode splits as below.
    1. Boot Header + Image Headers + Partition Headers + Bootloader
    2. Partiton1
    3. Partition2 ...
    Please run "bootgen -bif_help split" for more details.

    Hi Ramya,

           Thanks for your reply.
           My Scenario would be like assume I am using normal mode to split.
           So I  will be having 3 partitions:
           Partition 1 -> BH + IH + PH + FSBL
           Partition 2 -> Linux Kernel
           Partition 3 -> RootFS
           using 3 respective .bif files.
           
           Output:
           partition1.bin
           partition2.bin
           partition3.bin
           
           Can we able to load these .bin's as plain image? Also can we sign these bin's & authenticate using eFUSE keys?
