How to modify ota file with customize partition layout?

yi-chia.lan · January 5, 2023, 2:21am

Hi Nvidia,

We would like to upgrade jetson nx from 32.7.1 to 35.1 by ota payload package.
There is partition layout change already in our 32.7.1 : flash_l4t_t194_spi_emmc_p3668.xml add two partition between RECROOTFS and UDA as beneth:

        <partition name="RECROOTFS" type="data">
            <allocation_policy> sequential </allocation_policy>
            <filesystem_type> basic </filesystem_type>
            <size> RECROOTFSSIZE </size>
            <file_system_attribute> 0 </file_system_attribute>
            <allocation_attribute> 0x8 </allocation_attribute>
            <percent_reserved> 0 </percent_reserved>
            <description> **Optional.** Reserved for future use by the recovery filesystem;
              removable. </description>
        </partition>
        <partition name="ADRESERVE" type="data">
            <allocation_policy> sequential </allocation_policy>
            <filesystem_type> basic </filesystem_type>
            <size> 12288 </size>
            <file_system_attribute> 0 </file_system_attribute>
            <allocation_attribute> 0x8 </allocation_attribute>
            <percent_reserved> 0 </percent_reserved>
            <description> **Optional.** Reserved for ADLINK use. </description>
        </partition>
        <partition name="ADRESERVE_b" type="data">
            <allocation_policy> sequential </allocation_policy>
            <filesystem_type> basic </filesystem_type>
            <size> 12288 </size>
            <file_system_attribute> 0 </file_system_attribute>
            <allocation_attribute> 0x8 </allocation_attribute>
            <percent_reserved> 0 </percent_reserved>
            <description> **Optional.** Reserved for ADLINK use. </description>
        </partition>
        <partition name="UDA" type="data">
            <allocation_policy> sequential </allocation_policy>
            <filesystem_type> basic </filesystem_type>
            <size> 18432 </size>
            <file_system_attribute> 0 </file_system_attribute>
            <allocation_attribute> 0x808 </allocation_attribute>
            <percent_reserved> 0 </percent_reserved>
            <description> **Required.** Automatically takes all remaining space on the device except that
              occupied by the `secondary_gpt` partition. Allocation attribute must be set to 0x808.
              May be mounted and used to store user data. </description>
        </partition>

in 35.1, we also add these two partition in flash_l4t_t194_spi_emmc_p3668.xml

<partition name="RECROOTFS" type="data">
            <allocation_policy> sequential </allocation_policy>

            <file_system_attribute> 0 </file_system_attribute>
            <allocation_attribute> 0x8 </allocation_attribute>
            <percent_reserved> 0 </percent_reserved>
            <description> **Optional.** Reserved for future use by the recovery filesystem;
              removable. </description>
        </partition>
        <partition name="esp" type="data">
            <allocation_policy> sequential </allocation_policy>

            <size> 67108864 </size>
            <file_system_attribute> 0 </file_system_attribute>

            <filesystem_type> basic </filesystem_type>
            <size> 12288 </size>
            <file_system_attribute> 0 </file_system_attribute>
            <allocation_attribute> 0x8 </allocation_attribute>

        </partition>
        <partition name="ADRESERVE_b" type="data">

            <filesystem_type> basic </filesystem_type>
            <size> 12288 </size>
            <file_system_attribute> 0 </file_system_attribute>
            <allocation_attribute> 0x8 </allocation_attribute>
            <percent_reserved> 0 </percent_reserved>
            <description> **Optional.** Reserved for ADLINK use. </description>
        </partition>
        <partition name="UDA" type="data">

            <size> 18432 </size>
            <file_system_attribute> 0 </file_system_attribute>
            <allocation_attribute> 0x808 </allocation_attribute>
            <percent_reserved> 0 </percent_reserved>
            <description> **Required.** Automatically takes all remaining space on the device except that

        </partition>

for OTA package, we modify relation file as Image_based_OTA_Examples.txt example 1.
To build the payload, show error as beneth

For error , we can not figure out what’s wrong.
would nvidia kindly show us how to modify ota package file for our customized partition layout??

hello yi-chia.lan,

please refer to developer guide for this session, Update with Partition Layout Changes.

yi-chia.lan · January 16, 2023, 8:28am

Hi JerryChang,
I don’t think most of user can modify the file by reference to the online document. There is less information and guidance there.

Sorry for the late response, have you managed to get issue resolved or still need the support? Thanks

Hi kayccc,

no, still failed on generate payload image.
