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:

tlv_eeprom dev 0 tlv_eeprom erase tlv_eeprom set 0x21 'Clearfog Base' tlv_eeprom set 0x22 'SRCFCB9130IV14' tlv_eeprom set 0x23 'NG01725204200060' tlv_eeprom set 0x25 '12/24/2022 07:35:59' tlv_eeprom set 0x26 '0x14' tlv_eeprom set 0x2b 'IMI' tlv_eeprom set 0x2c 'PH' tlv_eeprom set 0x2d 'SolidRun' tlv_eeprom write

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.

Example

  • TLV_CODE_PRODUCT_NAME: CN9132 COM Express 7 Module

  • TLV_CODE_PART_NUMBER: SRC9132S64D00GE008V12

  • TLV_CODE_SERIAL_NUMBER: NG01848213000015

  • TLV_CODE_MANUF_DATE: 12/24/2022 07:35:59

  • TLV_CODE_DEVICE_VERSION: 0x12 (1.2)

  • TLV_CODE_PLATFORM_NAME: Octeon TX2
