Kasli-I2C

A collection of Python scripts for interacting with Kasli(-SoC) and other Sinara hardware over I2C, primarily for flashing firmware.

To run these scripts, no firmware is necessary on the Kasli(-SoC). The scripts interface directly with the I2C bus through USB (FTDI bridge).

Only power and USB connection need to be provided.

Flashing firmware on compatible boards

The flash_<device>.py scripts are used to flash the firmware on compatible Sinara cards.

The currently supported and used in production compatible cards are:

The phaser script has functionality limited only to EUI48 updates. For flashing firmware, use the JTAG method.

Usage

python flash_<device>.py <kasli-number> <eem-slot> <action>

Arguments

<device>: The type of card to flash. One of:
- flash_fastino.py
- flash_urukul.py
<kasli-number>: The number # of the Kasli board. Usually 0 if there is only one connected.
<eem-slot>: The EEM slot where the device is installed (e.g., EEM0, EEM1, etc.). The slot must correspond to EEM0 on the card to be flashed.
<action>:
- eeprom <EUI48>: Updates the EUI48 value on the EEPROM.
- read <dump-file>: Reads the flash content into a file. Must be followed by a file path.
- write <firmware-file>: Writes the firmware file to the flash. Must be followed by a file path.

Example

python flash_fastino.py 0 EEM1 write fastino_firmware.bin

Reads and prints the MAC address (EUI-48) from the Kasli EEPROM.

Usage

python kasli_get_mac.py [-s <kasli-number>]

-s <kasli-number>: (Optional) Number of the Kasli FTDI device. If not provided, it will try to connect to the first one found.

Example

python3 kasli_get_mac.py
