Olimex ARM USB TINY H and ARM USB OCD HThe Olimex. ARM USB TINY VID PID 1. BA 0. 00. 4 and ARM USB OCD 1. BA 0. 00. 3 can be used with flashrom for programming SPI chips. The ARM USB TINY H 1. BA 0. 02. A and ARM USB OCD H 1. BA 0. 02. B should also work, though they are currently untested. The following setup can then be used to flash a BIOS chip through SPI. On the ARM USB TINY, VREF, and VTARGET are internally connected, and all the GND lines even numbered pins, from 4 to 2. VCCGND between the voltage source and the target. The voltage source should provide 3. V to 3. 3. V DC but doesnt have to come from USB it can be as simple as two AA or AAA batteries placed in serial 2 x 1. V.
