In the pursuit of qualitative random numbers, people invent very ingenious adaptations (see, eg, ...

How I reanimated the device (JTAG emulator BH-USB-560v2) via U-Boot

I have doubts that the JTAG emulator for debugging processors from Texas Instruments is so common that its resuscitation would be of interest to someone.
