I'm seing pitiful performance when programming STM32 flash(9kBytes/ s).

It appears OpenOCD uses most of it's time in target_wait_state(), haven't

Has anyone done any work / measurements on Cortex target_write_memory()/
flash programming performance they would like to share?


What adapter are you using?

ZY1000, but I heard that this is the same with ftdi2232 like adapters. From profiling I see that most of the time is "spent" in target_wait_state().

I'd like to hear some performance numbers from anyone out there.

I haven't looked into any performance aspects of OpenOCD since I'm still more concerned with correct operation. That said, I can take a look at this on the host side. My day job is writing performance analysis tools.
