The archive-link and the one attached to your mail seem to be for some other problem? > Also increasing the stm32 driver (stm32x_write_block buffer_size) to 16k (if > you have enough target ram) Ok, increasing the buffer did help a bit: default 8192: wrote 112328 byte from file main.elf in 12.496000s (8.778434 kb/s) vs. 16384: wrote 112328 byte from file main.elf in 7.855000s (13.965030 kb/s) I think, 16384 (or even 65536?) should be made the default buffer_size, because stm32x_write_block will already try smaller values until it can allocate a buffer. Or perhaps it should just use the value from the config file? Possible bug: The default target/stm32.cfg script assumes a device with 16384 bytes of working area -- doesn't that break support for smaller CPUs with 10k or 6k of memory?
