## Platform Component Firmware

### Platform Component Firmware show commands

**show platform firmware**

This command displays platform components firmware status information.

- Usage:
```bash
show platform firmware
```

- Example:
```bash
root@sonic:/home/admin# show platform firmware
Chassis Module Component Version Description
--------- -------- ----------- ----------------------- ---------------------------------------
Chassis1 N/A BIOS 0ACLH004_02.02.007_9600 BIOS - Basic Input/Output System
CPLD 5.3.3.1 CPLD - includes all CPLDs in the switch
```

### Platform Component Firmware config commands

**config platform firmware install**

This command is used to install a platform component firmware.
Both modular and non modular chassis platforms are supported.

- Usage:
```bash
config platform firmware install chassis component <component_name> fw <fw_path> [-y|--yes]
config platform firmware install module <module_name> component <component_name> fw <fw_path> [-y|--yes]
```

- Example:
```bash
root@sonic:/home/admin# config platform firmware install chassis component BIOS fw /etc/mlnx/fw/sn3800/chassis1/bios.bin
New firmware will be installed, continue? [y/N]: y
Installing firmware:
/etc/mlnx/fw/sn3800/chassis1/bios.bin

root@sonic:/home/admin# config platform firmware install module Module1 component BIOS fw http://mellanox.com/fw/sn3800/module1/bios.bin
New firmware will be installed, continue? [y/N]: y
Downloading firmware:
[##################################################] 100%
Installing firmware:
/tmp/bios.bin
```
Supported options:
1. -y|--yes - automatic yes to prompts. Assume "yes" as answer to all prompts and run non-interactively
**config platform firmware update**
This command is used for automatic FW update of all available platform components.
Both modular and non modular chassis platforms are supported.
Automatic FW update requires `platform_components.json` to be created and placed at:
sonic-buildimage/device/<platform_name>/<onie_platform>/platform_components.json
Example:
1. Non modular chassis platform
```json
{
"chassis": {
"Chassis1": {
"component": {
"BIOS": {
"firmware": "/etc/<platform_name>/fw/<onie_platform>/chassis1/bios.bin",
"version": "0ACLH003_02.02.010",
"info": "Cold reboot is required"
},
"CPLD": {
"firmware": "/etc/<platform_name>/fw/<onie_platform>/chassis1/cpld.bin",
"version": "10",
"info": "Power cycle is required"
},
"FPGA": {
"firmware": "/etc/<platform_name>/fw/<onie_platform>/chassis1/fpga.bin",
"version": "5",
"info": "Power cycle is required"
}
}
}
}
}
```
2. Modular chassis platform
```json
{
"chassis": {
"Chassis1": {
"component": {
"BIOS": {
"firmware": "/etc/<platform_name>/fw/<onie_platform>/chassis1/bios.bin",
"version": "0ACLH003_02.02.010",
"info": "Cold reboot is required"
},
"CPLD": {
"firmware": "/etc/<platform_name>/fw/<onie_platform>/chassis1/cpld.bin",
"version": "10",
"info": "Power cycle is required"
},
"FPGA": {
"firmware": "/etc/<platform_name>/fw/<onie_platform>/chassis1/fpga.bin",
"version": "5",
"info": "Power cycle is required"
}
}
}
},
"module": {
"Module1": {
"component": {
"CPLD": {
"firmware": "/etc/<platform_name>/fw/<onie_platform>/module1/cpld.bin",
"version": "10",
"info": "Power cycle is required"
},
"FPGA": {
"firmware": "/etc/<platform_name>/fw/<onie_platform>/module1/fpga.bin",
"version": "5",
"info": "Power cycle is required"
}
}
}
}
}
```
Note: FW update will be skipped if component definition is not provided (e.g., 'BIOS': { })
- Usage:
```bash
config platform firmware update [-y|--yes] [-f|--force] [-i|--image=current|next]
```
- Example:
```bash
root@sonic:/home/admin# config platform firmware update
Chassis Module Component Firmware Version Status Info
--------- -------- ----------- ------------------------------------- ------------------------------------------------- ------------------ -----------------------
Chassis1 N/A BIOS /etc/mlnx/fw/sn3800/chassis1/bios.bin 0ACLH004_02.02.007_9600 / 0ACLH004_02.02.007_9600 up-to-date Cold reboot is required
CPLD /etc/mlnx/fw/sn3800/chassis1/cpld.bin 5.3.3.1 / 5.3.3.2 update is required Power cycle is required
New firmware will be installed, continue? [y/N]: y
Summary:
Chassis Module Component Status
--------- -------- ----------- ----------
Chassis1 N/A BIOS up-to-date
CPLD success
```
Supported options:
1. -y|--yes - automatic yes to prompts. Assume "yes" as answer to all prompts and run non-interactively
2. -f|--force - install FW regardless the current version
3. -i|--image - update FW using current/next SONiC image
Note: the default option is --image=current

## Platform Specific Commands
There are few commands that are platform specific. Mellanox has used this feature and implemented Mellanox specific commands as follows.
