I am having a problem while updating the firmware version to 1.3.0, which is present in the release of voyager-sdk 1.3.1 on GitHub (branch - release/v1.3). I am using the Aetina RK3588 Evaluation Kit. Here is the filename containing the firmware:

firmware_release_public_v1.3.0.tar.gz

The output of axdevice command is : 

Device 0: metis-0:1:0 1GiB m2 flver=1.3.0-rc3 bcver=1.4 clock=800MHz(0-3:800MHz) mvm=0-3:100%

Here is the error I am facing:

(venv) aetina@aetina:~/devel/axelera/firmware/firmware_release_public_v1.3.0$ ./flash_update.sh --fw-update
>>> Metis Firmware update
>>> the following operations updates the flash content
    Make sure to only run this operation if really needed
    Also make sure to not power cycle the devices or it might
    be rendered non-functional.
Do you want to continue? ?y/n] y

    you do have the following options:
    - power cycle the host, or
    - remove/rescan the pcie device
