[Verified] GL3224 chip usb3.0 card reader solution verification board

 
Overview

This is a solution verification board that uses GL3224 (32-pin version) as a USB3.0 card reader. Currently, a TF card version is produced, and an SD card version may be released in the future. It has been verified that it can be used. I don’t know how to wire, so please spray lightly.

The disassembled chip or the old version of this chip need to upgrade the firmware to use USB3.0. If you want to upgrade to a higher version of the firmware, you must weld the flash chip. I will post the specific update method and software package below.

Firmware upgrade: The specific tutorial is here https://blog.csdn.net/lyck0801/article/details/108402382
