A maker developer has squeezed an Arduino onto an SD card. He was inspired by Intel’s Edison compute module and he tried to go one better. The result is the SDuino, an ATMega328P processor-based ...

It turned out the SDIO mode on [Severin]’s card was broken, but accessing it with an Arduino and SPI mode worked. There was finally hope to get files off this damaged card.

BootDrive isn’t terribly different from using an Arduino as an ISP, only now AVRdude runs on the Arduino itself and no computer is required to put new firmware into the target Arduino.
