Hi!
When I flash some big image (~128kB) on STM32 without any tricks:
reset halt
stm32x mass_erase
flash write_image c:\\stm32.hex
I achieve speeds of 12kB. JTAG frequency is 1MHz.
When I use my reset init script which sets the flash latency to 2
cycles, starts the PLL with internal RC

Generally to improve performance of high latency devices,
your best bet is to do some profiling and figure
out whether it's possible to rewrite the OpenOCD
higher level code to issue longer clock/in out sequences.

Hi Øyvind,
So you achieved 100kbytes/sec on an LPC1778 ... Wow,
can you share your config file?
It's the board/mbc1700.cfg that is in origin/master.
Did you use the ZY1000 for
this test. I am using just a

Regarding flashing, I am using the mon flash write_image erase

command from GDB, I don't know if that is executing on the target..
Try just load from GDB.
Well I have tried that,

This test was caused by curiosity which started after reading one
forum post in which someone describes that in CrossWorks when using
the same JTAG he achieved almost 150kB/s, over 14x faster than OpenOCD.
