    Any idea to speed up sflash_write with openocd for mass production ?

      Hi All,

       

      For production reason, using openocd with sflash_write.tcl to program external flash is slow. (67KiB /s)

       

      We tried enabling MCU PLL clock and increasing adapter_khz to 8000 and achieved 140KiB/s.

      (more adapter_khz doesn't help)

       

      Is there any other parameter can be tuned for faster SPI flash programming ?

       

      ps. we are working on STM32 platform. but similar issue also apply to 439x platform.
