MacOS Firmware Upgrade

It is vital that the firmware update process (once started), is NOT interrupted. Any interruptions during firmware update may cause the device to malfunction. If a cold upgrade fails before completion then a system reboot may resolve the issue. The firmware update process should then be repeated to update the device firmware.

The User must stop all transcoding processes before performing a firmware upgrade, otherwise it may lead to a device malfunction.

A user can perform a cold upgrade on the Quadra device from a MacOS host terminal.

List all the Quadra devices detected by running the ni_rsrc_mon command:
```
sudo ni_rsrc_mon
```

Note the “DEVICE” name of the device you wish to upgrade (eg./dev/rdisk4)

The Quadra firmware update package is available in the Quadra SDK Release Package

 cd Quadra_V<version>

Change directory to the firmware directory

 cd Quadra_FW_V*_RC*/

Using the same command line terminal, start the firmware_upgrade_macos executable. It requires two arguments to perform the firmware upgrade
1. The Name of the device (e.g. /dev/rdisk4)
2. The Location of the nor_flash.bin (e.g. ./FL_BIN/nor_flash.bin)

To upgrade, use the following command:

 ./firmware_upgrade_macos /dev/rdisk4 ./FL_BIN//nor_flash.bin

Wait for about 2 minutes for the command to complete.

After the command completes its execution please reboot the host.
```
sudo reboot now
```
Confirm that the firmware version has been successfully upgraded, by running the following command
```
sudo ni_rsrc_list
```
The above output shows the F/W rev has been upgraded to ---6FDEV.

Perform these steps for each Netint device in the host.

CAUTION - Do not interrupt the upgrade process or send any commands to the card while the upgrade is progress.
