STM32F4 USB connection unrecognised

Posted by konje on 2017-05-18 19:56

Hi,

I am working on Ubuntu 16.04 and cant detect my STM32 discovery board on the system. I installed st-link and when I run st-util with board connected I get:

$ st-util
st-util 1.3.1
2017-05-18T18:51:43 WARN src/usb.c: Couldn’t find any ST-Link/V2 devices

Aslo when I try to detect the board by lsusb, fdisk or $ ls /dev/ | grep sd command, the board is not listed (as I would expect sdb* there). The output before and after running the comand is the same:
sda
sda1
sda2
sda3
sda4
sda5
sda6

I have jumpers on CN3 connectors. Can anyone help please? Does it has anything to do with the reset button - if yes how do you reset via terminal?

Hi Konje,

Did you check that Udev rules are installed ?
FYI The SystemWorkbench installer packages all the required stuff to enable STLink through USB.

Here are the expected rules: 

$ ls -1 /etc/udev/rules.d/*stlink*
/etc/udev/rules.d/49-stlinkv1.rules
/etc/udev/rules.d/49-stlinkv2-1.rules
/etc/udev/rules.d/49-stlinkv2.rules

Yes, I have them isntalled. Also I checked the board on another PC that I programmed the STM board before and I also got connection error this time. The power led lights up and programator LED1 blinks red - if thats any indication.

I imagine that udev rules should work on reboot. Alternativelly, I treid restart udev rules command but for some reason that command didnt work, I got: “failed to connect to upstart” (apparetnly upstart was replaced by systemd).

I’m having a very similar issue — plugging my dev board (Nucleo-F091) into the USB isn’t showing up when I run `lsusb`. Also running Ubuntu 16.04.

I copied the udev rules so there’d be one with an `stlink` group permission (and added myself to it) with no visible effect. Any pointers of what else to look at?
