PCIe Retimer

Upgrading the PCIe Retimer Firmware

Both the firmware and upgrade tool are packaged into the file system, you can find them in the following locations:

• Firmware

  /lib/firmware/astera_retimer/firmware/pt4080l/1.13.x/nvidia_p3713_x4x4/nvidia_p3713_x4x4_X8-B2B_RETIMER-DYN_PRT_ORIENT-SRNS-VPH1P8V-HOT_PLUG_v1_13_9.ihx

• Tool

  /lib/firmware/astera_retimer/tools/eeprom

Run the following command to upgrade the retimer firmware:

sudo /usr/lib/firmware/astera_retimer
/tools/eeprom/usr/lib/firmware/astera_retimer/firmware/pt4080l/1.13.x/nvidia_p3713_x4x4/nvidia_p3713_x4x4_X8-B2B_RETIMER-DYN_PRT_ORIENT-SRNS-VPH1P8V-HOT_PLUG_v1_13_9.ihx

If the flashing is successful, you will see the following message:
