When developing or testing firmware on a hardware platform, the developers have to either move flash chips between the target and a programmer, use a target board that is prepared to be used with a flash programmer connected or use an expensive SPI flash emulator instead of the flash chip. For bigger companies and few devices, the latter is quite affordable, but for the other cases, the cost can become a limiting factor. In this lightning talk, I'll give a short presentation on the qspimux2, which is a small board that sits between the mainboard and the SPI flash, connects to a programmer and makes sure that board and programmer won't interfere when accessing the flash.
