USB to Ethernet circuit board based on RTL8152B, compatible with SR9900

Overview

Universal RTL8152B USB to Ethernet circuit board, compatible with SR9900

Pid Vid MAC product device name, serial number, LED configuration and other information can be programmed through PGTOOL software. The information is stored in the EFUSE inside the chip, with a limit on the number of write modifications; it can also be stored in an external eeprom chip. This project does not have this part of the circuit.

ISO files can be uploaded to external FLASH memory through PGTOOL software. When the computer does not have a driver, the chip will automatically pop up the USB virtual optical drive after 10 seconds.

If the chip's Vid and Pid are not the default 0x0BDA, 0x8152. If the PGTOOL software cannot recognize it, you can first modify the vid and pid in the configuration file to be consistent with the hardware, and then burn it to the default vid and pid. Convenient automatic driver loading

Long ping return time
I have a question. I use 107vc to make a network control device. When I ping its IP, the response time is long and inconsistent, sometimes hundreds of milliseconds, and the longest is 1000 millisecond
Some knowledge about MAP files
This article comes from HELLODSP exchange network. Author: huttu. Recently, many friends have asked about MAP files. Now I will share my understanding of MAP files with you. MAP files are a kind of ma
Has anyone successfully applied for a sample from ST?
I recently applied for several samples through TI. Suddenly I had an impulse to try whether the ST chips that are being used in batches can be successfully applied for, and by the way, apply for a few
