1 What: /sys/bus/i2c/devices/<mcu_device>/board_revision 2 Date: September 2024 3 KernelVersion: 6.11 4 Contact: Marek Behún <kabel@kernel.org> 5 Description: (RO) Contains board revision number. 6 7 Only available if board information is burned in the MCU (older 8 revisions have board information burned in the ATSHA204-A chip). 9 10 Format: %u. 11 12 What: /sys/bus/i2c/devices/<mcu_device>/first_mac_address 13 Date: September 2024 14 KernelVersion: 6.11 15 Contact: Marek Behún <kabel@kernel.org> 16 Description: (RO) Contains device first MAC address. Each Turris Omnia is 17 allocated 3 MAC addresses. The two additional addresses are 18 computed from the first one by incrementing it. 19 20 Only available if board information is burned in the MCU (older 21 revisions have board information burned in the ATSHA204-A chip). 22 23 Format: %pM. 24 25 What: /sys/bus/i2c/devices/<mcu_device>/front_button_mode 26 Date: September 2024 27 KernelVersion: 6.11 28 Contact: Marek Behún <kabel@kernel.org> 29 Description: (RW) The front button on the Turris Omnia router can be 30 configured either to change the intensity of all the LEDs on the 31 front panel, or to send the press event to the CPU as an 32 interrupt. 33 34 This file switches between these two modes: 35 - ``mcu`` makes the button press event be handled by the MCU to 36 change the LEDs panel intensity. 37 - ``cpu`` makes the button press event be handled by the CPU. 38 39 Format: %s. 40 41 What: /sys/bus/i2c/devices/<mcu_device>/front_button_poweron 42 Date: September 2024 43 KernelVersion: 6.11 44 Contact: Marek Behún <kabel@kernel.org> 45 Description: (RW) Newer versions of the microcontroller firmware of the 46 Turris Omnia router support powering off the router into true 47 low power mode. The router can be powered on by pressing the 48 front button. 49 50 This file configures whether front button power on is enabled. 51 52 This file is present only if the power off feature is supported 53 by the firmware. 54 55 Format: %i. 56 57 What: /sys/bus/i2c/devices/<mcu_device>/fw_features 58 Date: September 2024 59 KernelVersion: 6.11 60 Contact: Marek Behún <kabel@kernel.org> 61 Description: (RO) Newer versions of the microcontroller firmware report the 62 features they support. These can be read from this file. If the 63 MCU firmware is too old, this file reads 0x0. 64 65 Format: 0x%x. 66 67 What: /sys/bus/i2c/devices/<mcu_device>/fw_version_hash_application 68 Date: September 2024 69 KernelVersion: 6.11 70 Contact: Marek Behún <kabel@kernel.org> 71 Description: (RO) Contains the version hash (commit hash) of the application 72 part of the microcontroller firmware. 73 74 Format: %s. 75 76 What: /sys/bus/i2c/devices/<mcu_device>/fw_version_hash_bootloader 77 Date: September 2024 78 KernelVersion: 6.11 79 Contact: Marek Behún <kabel@kernel.org> 80 Description: (RO) Contains the version hash (commit hash) of the bootloader 81 part of the microcontroller firmware. 82 83 Format: %s. 84 85 What: /sys/bus/i2c/devices/<mcu_device>/mcu_type 86 Date: September 2024 87 KernelVersion: 6.11 88 Contact: Marek Behún <kabel@kernel.org> 89 Description: (RO) Contains the microcontroller type (STM32, GD32, MKL). 90 91 Format: %s. 92 93 What: /sys/bus/i2c/devices/<mcu_device>/reset_selector 94 Date: September 2024 95 KernelVersion: 6.11 96 Contact: Marek Behún <kabel@kernel.org> 97 Description: (RO) Contains the selected factory reset level, determined by 98 how long the rear reset button was held by the user during board 99 reset. 100 101 Format: %i. 102 103 What: /sys/bus/i2c/devices/<mcu_device>/serial_number 104 Date: September 2024 105 KernelVersion: 6.11 106 Contact: Marek Behún <kabel@kernel.org> 107 Description: (RO) Contains the 64-bit board serial number in hexadecimal 108 format. 109 110 Only available if board information is burned in the MCU (older 111 revisions have board information burned in the ATSHA204-A chip). 112 113 Format: %016X.
