Support for CFI compliant flashes has been added to OpenOCD. Currently, only flashes compatible with the Intel command sets (0×0001 and 0×0003) are supported. Flash writing is possible both using memory writes (slow) and using flash writing code running on the target (faster). Using the Amontec JTAG Accelerator, about 30 kByte/s can be flashed. The CFI flash code has been tested with an Intel 28F640J3 and an Intel TE28F320C3, both in x16 configuration on a 16-bit bus, but support is included for any combination of up to 32-bit busses.
