ISSUES LOADING MicroPython in the Discovery STM32F401

[sajulios]

Hi guys I want to run Micropython on the Discovery STM32F401 Board but even though I followed all the steps at the end when I run the stlink: sudo ~/stlink/st-util on ubuntu and then on a separate command window I run the following arm-none-eabi-gdb build-STM32F4DISC/firmware.elf I get the following massage :
Type "apropos word" to search for commands related to "word"...
Reading symbols from build-STM32F4DISC/firmware.elf...(no debugging symbols found)...done.

I followed the steps found the this link : http://gpio.kaltpost.de/?p=2082

Could you guide me on the process I don{t know if I missed anything?

Thanks

The STM32F4DISC build is for an F405/F407 chip. It won't work on an F401. You can try modifying the configuration to make it correct for the F401. Or you could try the ESPRUINO PICO port which is for the F401.

I've used the espruino pico several times and flashed it using dfu without any issues.

The tricky bit with the pico is getting it into dfu mode in the first place.
