# AMR Updating PDI in Flash

1. The ami\_tool cfgmem\_info command will list the available partitions that have been defined in the FPT.

        # Usage: ami_tool cfgmem_info -d <bdf> -t <type> [options...]
        ami_tool cfgmem_info -d 21:00.0 -t primary
    
        Primary FPT:

2. The ami\_tool cfgmem\_program command can then be used to write a amr_ospi.bin pdi to a partition 1 and 2. Partition 3 user partition which is used to load user PL pdi's
through ami\_tool pdi_\program command.

    e.g.

        ```bash
        # usage: sudo ami_tool cfgmem_program -d <bdf> -t <type> -i <pdi path> -p <flash partition number>
        sudo ami_tool cfgmem_program -d 21:00.0 -t primary -i <path_to_amr_ospi.bin> -p 0
        ```

        Will do a hot reset to boot into partition 0. This may take a minute...

**Note:** Once the flash programming starts, as indicated by the progress bar percentage. Once after a hot reset, we can see updated PDI info using ami\_tool overview command.

3.  Unless the -q option was specified, AMI will automatically instruct a boot to occur from the newly updated partition upon the completion of the cfgmem\_program command.

Subsequent boots from any of the available PDI\_BOOT partitions can be performed using the ami\_tool device\_boot command.

    sudo ami_tool device_boot -d 21:00.0 -p 0

When using this approach it is important to make sure that the version of AMI is compatible with the version of AMC which is running on the card (compatibility is indicated by having the same Major & Minor version numbers in the AMI/AMC **Major.Minor.Patch** version number format.)
