Programming STM32 in bootloader mode under Linux

[Davorin]

Good evening (o;

Now that my test setup works fine with setting the RTC via USB CDC and entering USB DFU mode due to the excellent help from the community members here....the next little problem arises (o;

Which program can be used nowadays under Linux to flash a STM32 MCU in USB DFU mode?

The STM32Cube programmer installs nice on Debian 10 and Ubuntu 20.04, but fails to start due to Java error...and guess this error exists since a long time and ST doesn't seem to care about it...

So is there another program for programming in DFU mode under Linux?

And if so...what input file format it expects? Something that comes strait out of STMCubeIDE?

 Or is there a sample CLI application which uses libusb to flash the MCU?

thanks in advance

Hi I am using st-link, but for dfu I would try dfu-programmer and dfu-util packages.

Ah great..thanks 🙂

So I can just throw the .bin file at it?

Or does the .bin/.elf file needs conversion? As I remember vagely dfu_util uses .hex files...

please see - http://dfu-util.sourceforge.net/dfuse.html

Just great 🙂

Can sent it to DFU mode with:

echo "X1704" > /dev/ttyACM1

flash it then:

dfu-util -a 0 -s 0x08000000:leave -D ./USB_Thermologger_2/Debug/USB_Thermologger_2.bin
dfu-util 0.9
