Hi
I've setup a project dir for openocd with this config and it works like the
command line version:
source [find interface/stlink.cfg]
# GDB can also flash my flash!
gdb_memory_map enable
gdb_flash_program enable
source [find target/stm32f4x.cfg]
So, now I want to flash micropython onto the STM32F401. So far I've done that
with a DFU mode file that
micropython compiles for me, and otherwise it makes two files. Is doing 2
files easy?
Here's how the DFU flashing goes:

The files I get are:
firmware0.bin
firmware1.bin
program uses erase then write, so probably wants just one file, so maybe I need
to use:
flash write_bank 0 firmware0.bin 0x08000000 (flash write_bank num filename
offset)
flash write_bank 1 firmware1.bin 0x08020000 (flash write_bank num filename
offset)
flash verify_bank 1 firmware1.bin 0x08020000 (flash verify_bank num
filename offset)
flash verify_bank 0 firmware0.bin 0x08000000 (flash verify_bank num
filename offset)
