Accessing the IF820 Flasher CLI help screen

You can access the help screen with the following command

if820_flasher_cli.exe -h

Which outputs the following

>if820_flasher_cli.exe -h

usage: if820_flasher_cli [-h] [-c CONNECTION] [-ce] [-d] [-f FILE]

CLI tool to flash an IF820 board (or compatible boards) with new firmware.

If no COM port is specified, the tool will automatically detect the board and flash it.

If there is more than one board detected, the user will be prompted to select the board to flash.

The CLI supports chip erase, firmware update, and flashing firmware with chip erase.

options:

  -h, --help            show this help message and exit

  -c CONNECTION, --connection CONNECTION HCI COM port

  -ce, --chip_erase     perform full chip erase.

  -d, --debug           Enable verbose debug messages

  -f FILE, --file FILE  application hex file to flash

-c lets the user specify a COM port which then ignores and DVK probe automation. This will let the user flash custom boards with any UART device.

-ce performs a chip erase (recommended) but they may be occasions you want to retain certain settings.

-d provides extra debug output and may be requested by Ezurio support, should you be having issues with the IF820 Flasher CLI on your system.

-f defines the file name and path of the firmware image to be flashed.

In addition to the code examples that are available in the AIROC™ Bluetooth® SDK, there are optional sets of packages that add extra features to the AIROC™ Bluetooth® SDK. These are typically more complex applications or require special licensing. The Pro CEs are not available on GitHub repositories.

The formal way Pro Examples are shared is by the customer creating an account in the Infineon Developer Community and by getting their registered Email ID and account username.

The customer needs to share their MFi License details with Infineon.

The Infineon marketing team will then upload the Pro Example in the community.

The Vela  IF820 DVK uses a RP2040 to provide UART com ports for the DVK.

You can check the version of RP2040 firmware using the following, which assumes you have Python and pyocd installed.

pyocd list -v -v -v

which should return the RP2040 firmware of all boards currently connected which should look something like this

PS C:\Python311> pyocd list -v -v -v

If using MODUS Toolbox on the IF820 it can support Hands Free Profile (HFP) over the I2S/PCM interface. Infineon, in MODUS Toolbox, supports mSBC and CVSD audio CODECs in FW which is used in HFP.

SBC CODEC which is used as the compression algorithm for Advance Audio Distribution Profile (A2DP) could be done in FW as well but the I2S interface doesn’t support 44KHz/48KHz sample rates, thus, it can’t be used for A2DP.

There is no support for LE Audio.
