Dumping Firmware With the CH341a Programmer | by Rick Wisser 

Note: This blog will also be a lab for any of the upcoming Wild West Hackin’ Fest Conferences. During a recent engagement, I came across an issue. The issue I encountered was that the SPI chip I was trying to dump the firmware off of was a 1.8v chip. This would not have been a problem but both the shikra and bus pirate are rated for 3.3v chips. I considered creating a voltage divider to step the voltage down but after a little Googling, I came across the CH341a with the 1.8v adapter. I decided to order it with one-day shipping. After I worked with it and was able to successfully dump the firmware from the 1.8v IC without having to remove the SPI chip from the circuit board, I decided to write a blog about it. This blog is targeted for all audiences. It might be a little too....
