Introduction
Starting from April 01. 2022, the EEPROMs on Carriers, SoMs and COM-Express Modules are being programmed with identifying information such as the product name and SKUs to allow for programmatic identification of hardware. The data is is structured according to the ONIE TLV Standard.
Carrier
The EEPROM on Clearfog Base and Pro on i2c-0 at 0x52 is programmed with the following TLV entries:
TLV_CODE_PRODUCT_NAME (mandatory) Human-readable name of the Product.
TLV_CODE_PART_NUMBER (mandatory) Identifying part number from ordering system (SKU) without BOM suffix (/0).
TLV_CODE_SERIAL_NUMBER (mandatory)
TLV_CODE_MANUF_DATE (mandatory) Manufacturing Date (MM/DD/YYYY HH:MM:SS)
TLV_CODE_DEVICE_VERSION (mandatory) Board Revision, incremented when parts or layout changes; MAJOR.MINOR revisions are encoded by storing MAJOR in the four most significant bits, MINOR in the four least significant bits.
TLV_CODE_MANUF_NAME (mandatory)
TLV_CODE_MANUF_COUNTRY (mandatory)
TLV_CODE_VENDOR_NAME (mandatory) Name of Vendor, typically SolidRun.
Example
TLV_CODE_PRODUCT_NAME: Clearfog Base
TLV_CODE_PART_NUMBER: SRCFCB9130IV14
TLV_CODE_SERIAL_NUMBER: NG01725204200060
TLV_CODE_MANUF_DATE: 12/24/2022 07:35:59
TLV_CODE_DEVICE_VERSION: 0x14 (1.4)
TLV_CODE_MANUF_NAME: IMI
TLV_CODE_MANUF_COUNTRY: PH
TLV_CODE_VENDOR_NAME: SolidRun
Programming from U-Boot
The EEPROM can be programmed from the U-Boot cli accordingly by the following commands:
COM Express
The EEPROM on CN913x CEX-7 Modules on i2c-0 at 0x50 is programmed with the following TLV entries:
TLV_CODE_PRODUCT_NAME (mandatory) Human-readable name of the Product.
TLV_CODE_PART_NUMBER (mandatory) Identifying part number from ordering system (SKU) without BOM suffix (/0).
TLV_CODE_SERIAL_NUMBER (mandatory)
TLV_CODE_MAC_BASE (optional) First MAC Address for the on-COM (SoC) network interface(s)
TLV_CODE_MANUF_DATE (mandatory) Manufacturing Date (MM/DD/YYYY HH:MM:SS)
TLV_CODE_DEVICE_VERSION (mandatory) Board Revision, incremented when parts or layout changes; MAJOR.MINOR revisions are encoded by storing MAJOR in the four most significant bits, MINOR in the four least significant bits.
TLV_CODE_PLATFORM_NAME Family name for the SoC.
TLV_CODE_MAC_SIZE (optional) Number of consecutive MAC Addresses starting from TLV_CODE_MAC_BASE. Usually 1.
TLV_CODE_MANUF_NAME (mandatory)
TLV_CODE_MANUF_COUNTRY (mandatory)
TLV_CODE_VENDOR_NAME (mandatory) Name of Vendor, typically SolidRun.
