Bricking and unbricking Vontar X96 mini 68.4k views.New version of Lenkeng HDMI over IP extender – LKV373A (Update 6.Until I have found the second one, I also used a kernel module which adds /dev/i2c-x interface driver and wrote a script for writing eeproms here:Įnjoy whichever method you like. One which does pretend to support eeproms smaller than 128kb ( this one ) and one which really does ( this one ). There are two forks of ch341eeprom on github. After setting the length manually, I was able to download complete data from my flash.Īfter some time I also needed to use it for 24C… programming.
So I forked the original github repo and added an option to manually set memory length. Unfortunately, when I tried to read memory contents I was only able to get first few bytes of my memory, probably because the chip was detected incorrectly. After compiling and connecting my chip, I was able to read info about my flash. The second one is for 25Q… SPI flash chips so it was my choice. The first one can be used for programming 24C… I2C EEPROMs. You can easily find the original utility & driver for Windows on the Internet but the chip manufacturer doesn’t provide software for Linux.Īfter examining the board I found out that the chip is CH341A ( datasheet) so I googled for some Linux software and I’ve found 2 opensource drivers: So I have ordered this cheap USB serial EEPROM programmer on ebay. I n eeded to backup original firmware of my favorite Chinese wireless router but I didn’t want to spend much time with hacking the embedded Linux.
