Appendix A

How to use AQ_API in U-Boot to Flash Firmware for

Aquantia PHY

This appendix describes the steps required to use AQ_API in U-Boot to flash firmware

for Aquantia PHY. The prerequisites are given below:

• The AQ_API version is 2.1.0

• The U-Boot is for T1024RDB

• The U-Boot source code is from SDK1.7 and later versions

Perform the following steps to use AQ_API in U-Boot:

1. Apply the following three patches to the U-Boot tree:

• added-source-codes-of-API-2.1.0.patch: Adds the source code of AQ_API 2.1.0. It

copies all the AQ_API source code (*.c, *.h) into one folder in U-Boot.

• AQ_API-fix-compile-error-for-API-2.1.0.patch: Fixes the compilation issues that

occurred in the original source code while building U-Boot.

• mdio-added-flash-command.patch: Adds an MDIO flash command for U-Boot. This

command will call a function in AQ_API to perform the actual flash

programming.

2. Build and update a new U-Boot on the T1024RDB board.

The Aquantia AQR105 PHY firmware has been programmed to PHY when shipping the

board to customers, there is no need to update PHY firmware. If it is still required to

update the PHY firmware, follow the instructions given below:

• Program AQR105 PHY firmware for 10G XFI (using RCW 0x95):
