No STM32 device in DFU mode connected

[Jaglaz]

Hi all,

I'm trying to customize the device tree of the stm board, but I'm stuck early on. I'm trying to follow stm32mp157c-dk2 tutorial to flash Starter Package (https://wiki.st.com/stm32mpu/wiki/STM32MP15_Discovery_kits_-_Starter_Package), however, when I reach the step

PC $> STM32_Programmer_CLI -l usb

I get the following output

~/stm32mpu-workspace/stm32mpu-tools/stm32-cube-programmer-240/bin/STM32_Programmer_CLI -l usb
 -------------------------------------------------------------------
 STM32CubeProgrammer v2.4.0 
 -------------------------------------------------------------------
 
===== DFU Interface =====
 
No STM32 device in DFU mode connected
 

my host kernel version: 4.4.0-174-generic

Hi,

did you set the Boot switches accordingly (both to the off position)? Did you connect the PC using the USB CN7 port (the USB-C port next to the USB-A ones)?

I am using Windows and a virtual Ubuntu 18.04 and have no problem connecting to mine.

Hope it helps

I have a kernel version 5.3.0 though

​Hi @Jarosław Głazowski​ 

Did you proceed to following step in wiki ?

4.2 USB serial link↑

• Install the libusb on your host computer

PC $> sudo apt-get install libusb-1.0-0

• To allow STM32CubeProgrammer to access the USB port through low-level commands, proceed as follows

PC $> cd $HOME/STM32MPU_workspace/STM32MPU-Tools/STM32CubeProgrammer-x.y.z/Drivers/rules

PC $> sudo cp *.* /etc/udev/rules.d/

Does your board boot switch in position 00 for USB/UART boot ?

Hope it help,

Olivier

This was the right answer for me!!

The device in my case responds as /dev/ttyACMx UART device, the flashing seems to be going without problems.

Sorry guys, didnt notice your answers. Silly me, @Fee ok I think we identified the curlpit I connected it to the STLink (CN11) :hear_no_evil_monkey: . I'll test it once the flashing is done. @OlivierG yes I did those steps.

Hi all, now that I connected everything in the right manner the device responds as it should. Comprehensive reading would be a nice skill to have ;)
