New post: Hacking SD Card & Flash Memory Controllers

New post: Hacking SD Card & Flash Memory Controllers

[Bunnie] and [xobs] went around buying many different microSD cards in order to find a hackable one. In their talk at 30C3 (slides here ), they reported their findings on a particular microcontroller brand, Appotech, and its AX211/AX215. By reverse engineering the firmware code they found online, they discovered a simple “knock” sequence transmitted over manufacturer-reserved commands that dropped the controller into a firmware loading mode. From there, they were able to reverse engineer most of the 8051 microcontroller function-specific registers, allowing them to develop novel applications for it. Some of the initial work was done using a FPGA/i.MX6-based platform that the team developed named Novena , which we hope may be available for purchase some day. It was, among others, used to simulate the FLASH memory chip that the team had previously removed. A video of the tal...
