The Spansion FM4 family of microcontrollers does not offer a way to identify the chip model nor the flash size, except for Dual Flash vs. regular layout. Therefore the family is passed as argument and wildcard-matched - MB9BFx6x and S6E2CC families are supported. Iterations showed that ... 1) Just doing the flash command sequence from SRAM loader code for each half-word took 20 minutes for an 8 KB block. 2) Doing the busy-wait in the loader merely reduced the time to 19 minutes. 3) Significant performance gains were achieved by looping in loader code rather than in OpenOCD and by maximizing the batch size across sectors, getting us down to ~2 seconds for 8 KB and ~2.5 minutes for 1.1 MB. (Tested with SK-FM4-176L-S6E2CC-ETH v11, CMSIS-DAP v23.) gcc, objcopy -Obinary and bin2char.sh are used for automating the integration of hand-written assembler snippets.
