Tried programming STM32F1x using STM32_Program_CLI with both STLink/V2 & ST Link/V3 in SWD mode. Programming time for 640KB look same 30sec for V2 & V3 diff under 0.5sec -Why timings same? UM0892 doc says max SWD freq. for V2 is 4Mhz & for V3 is 24Mhz.

Is there a way to reduce programming time with ST Link/V3?

Programming times are mostly erase and programming times. SWD frequency is mostly so high that there is no noticable influence. B.t.w, what is the size of your binary?
