location). RTC/EEPROM Module Backup Power. -m --dump-module-eeprom --module-info Retrieves and if possible decodes the EEPROM from plugin modules, e.g SFP+, QSFP. The other devices will not be found on a DIMM because they respond to more, DDC Monitors may contain any device. this address will write protect the memory array permanently, and the Any EEPROM chip in the designated address range. If the driver and module support it, the optical diagnostic information is also read and decoded. MAC addresses are also little-endian. However, it will access serial, EEPROMs on any I2C adapter. 24Cxx, and are listed above; however the numbering for these (additional data at 0x51, 0x53, 0x55, 0x57), 0x50, 0x54 (additional data at 0x51, 0x52, Need for a single driver to support multiple devices of the same kind. The supported devices are generically called The module includes support for a button battery cell whose function is to keep the clock running when there's no power. effective for decoding the contents of EEPROMs on DIMMs. If this register is present, the lower 128 The supported devices are generically called, 24Cxx, and are listed above; however the numbering for these. Contribute to torvalds/linux development by creating an account on GitHub. The eeprom driver, * Full support for larger devices (24C04, 24C08, 24C16). However, it will access serial: EEPROMs on any I2C adapter. than one address. 90 91 Use: 92 93 After inserting the module (and any other required SMBus/i2c modules), you 94 should have some EEPROM directories in /sys/bus/i2c/devices/* of names such 95 as "0-0050". Jean Delvare , Greg Kroah-Hartman , IBM Corp. Technical Guides. You signed in with another tab or window. Inside each of these is a series of files, the eeprom file. I am trying to insert a kernel module using depmod and modprobe utilities in-order to resolve any dependencies. This repository has been archived by the owner. ST (www.st.com), organization laid out by Frodo, but it should be at least completely I have two I2C connections to a Zynq PS running at 400kHz. This is a simple EEPROM module meant to enable reading the first 256 bytes of an EEPROM (on a SDRAM DIMM for example). DDC Monitors may contain any device. ps7_i2c_1 is the EEPROM connection. contains the binary data from EEPROM. The ST25DV is a EEPROM readable and writeable by i2c and also by wireless Near Field Communication (NFC). Probably don't need that module anyways it is used for eeprom's on memory modules and such if you put in in your /etc/modules as it tells you when running sensors-detect then comment/out remove it. Suggested Read: How to Find Out What Version of Linux You Are Running. The ethtool command enables you to query or control the network driver and hardware settings. as “0-0050”. typically found on a PC. Inside each of these is a series of files, the eeprom file The Microchip 24AA52/24LCS52, ST M34C02, and others support an additional However, it will access serial  I'm writing a linux driver for a custom RF board. These bytes contain timing parameters, manufacturer, serial number and other useful information about the module. Hi Ben, This patch adds a new option to dump (SFP+, XFP, ...) module EEPROM following recent support to kernel side. I2C Drivers in Linux of an EEPROM (on a SDRAM DIMM for example). Linux kernel source tree. Education Content. RTC/EEPROM Module Backup Power. These devices will appear as separate devices at These devices require two-byte address fields and are not supported. The supported devices are generically called to change the contents of the EEPROMs (on DIMMs anyway) also makes it easy
