I want to add new partition that dont mount in the system

Hi everyone,

I’m the new of jetson. I want to add the recovery partition to the tegra (TX1 & TX2).

So I downsize of the APP(system.img), the flash.xml is like the below.


    <partition name="APP" type="data">
        <allocation_policy> sequential </allocation_policy>
        <filesystem_type> basic </filesystem_type>
        <size> 28991029248 </size>
        <file_system_attribute> 0 </file_system_attribute>
        <allocation_attribute> 0x8 </allocation_attribute>
        <percent_reserved> 0 </percent_reserved>
        <filename> system.img </filename>
    </partition>
    <partition name="REC" type="data" oem_sign="false">
            <allocation_policy> sequential </allocation_policy>
            <filesystem_type> basic </filesystem_type>
            <size> 1572864000 </size>
            <file_system_attribute> 0 </file_system_attribute>
            <allocation_attribute> 0x8 </allocation_attribute>
            <percent_reserved> 0 </percent_reserved>
            <filename> rec.img </filename>
    </partition>

and it is successfual to add the REC partition. But…

When i login the ubuntu, i see the REC partition that mount the sd card.

So…How do i do to hide the REC partition, and dont mount it.

Thx
