What: /sys/bus/i2c/devices/<mcu_device>/board_revision
Date: September 2024
KernelVersion: 6.11
Contact: Marek Behún <kabel@kernel.org>
Description: (RO) Contains board revision number.
Only available if board information is burned in the MCU (older
revisions have board information burned in the ATSHA204-A chip).
Format: %u.
What: /sys/bus/i2c/devices/<mcu_device>/first_mac_address
Date: September 2024
KernelVersion: 6.11
Contact: Marek Behún <kabel@kernel.org>
Description: (RO) Contains device first MAC address. Each Turris Omnia is
allocated 3 MAC addresses. The two additional addresses are
computed from the first one by incrementing it.
Only available if board information is burned in the MCU (older
revisions have board information burned in the ATSHA204-A chip).
Format: %pM.
What: /sys/bus/i2c/devices/<mcu_device>/fw_features
Date: September 2024
KernelVersion: 6.11
Contact: Marek Behún <kabel@kernel.org>
Description: (RO) Newer versions of the microcontroller firmware report the
features they support. These can be read from this file. If the
MCU firmware is too old, this file reads 0x0.
Format: 0x%x.
What: /sys/bus/i2c/devices/<mcu_device>/fw_version_hash_application
Date: September 2024
KernelVersion: 6.11

Date: September 2024
KernelVersion: 6.11
Contact: Marek Behún <kabel@kernel.org>
Description: (RO) Contains the selected factory reset level, determined by
how long the rear reset button was held by the user during board
reset.
Format: %i.
What: /sys/bus/i2c/devices/<mcu_device>/serial_number
Date: September 2024
KernelVersion: 6.11
Contact: Marek Behún <kabel@kernel.org>
