Re: [Paparazzi-devel] Stm32f4 discovery dfu problem

[Prof. Dr.-Ing. Heinrich Warmers]

Hi Chris,
you need only 3 wires to connect  the 2 wire interface of you discovery  PCB  to other  STM 32 processors and open two bridges.
With the discovery pcb you get a debug interface for all stm32  controllers for only 15 euros.
We have tested this also and it works perfect.

I just uploaded the ap firmware using both the dfu-util and the stlink.
I must say that for the discovery board stlink is so much better but the dfu-util is the only way when you have a lonely stm32f4 chip.

Hi Chris,

you are trying to use stm32_mem.py to flash the discovery board. It currently doesn't have the stm bootloader in it's recognized devices, since to my knowledge no one tested it with that.

You could either try to specify the "--product any" option or simply use dfu-util instead of stm32_mem.

In latest master STLlink is the default (which should also be more convenient, as you don't have to enter bootloader mode manually first). Otherwise just select DFU-UTIL from the flash mode drop down menu.

Cheers, Felix

What does dfu-util --list output ? You should see the stm32 boards since it is also listed in lsusb.

I can get the mcu in dfu mode but paparazzi center keeps saying :

Hello

Get well soon ! :)

copied from the wiki:

push MCU in DFU mode: connect mini and micro USB to PC, connect pin BOOT0 with 3V (if it doesnt work also BOOT1 (PB2) with GND), press reset button(LED LD7 should light up now), disconnect BOOT0 to 3V

Best regards
Marius

I was a little sick and now i either forgot how to enter the bootloader mode (upload the ap firmware)
on my stm32f4 discovery board or something is wrong.
The discovery board enters the bootloader mode but paparazzi center does not see it.
To enter the dfu bootloader i just connect boot1 with vdd (3v) and the udev rules are copied.
Any ideas?
