STM32MP157C-DK2 w/ Debian 9 does not see USB devices

Embedded Linux Discussions
1

Building Debian 9 from https://www.digikey.com/eewiki/display/linuxonarm/STM32MP1#STM32MP1-Debian9 appears to have an issue with “classic” USB devices not being recognized. It’s not seeing either of my keyboards or a USB thumb-drive. Nothing in dmesg about USB insertions / removals. Not sure about USB-C, I don’t have any USB-C devices.

Here’s the dmesg log from the boot, and after a couple keyboard plug / unplugs.

Hi,
I have the same issue.
Do you have any progress on the solution for this problem?
Kind regards.

4

Nope, still no joy. Tried 5.3.x-rc3 with Debian 10.0 image, and while it registers the hidcore, it’s still not seeing any USB devices. I’m wondering if the vdd_usb: disabling has anything to do with it.

@jcwren, there are 5 more usb patches just recently posted to the u-boot list to get usb working in u-boot. Similar phy changes will be also needed for the kernel driver.

Regards,

6

Excellent, I will keep an eye out for those. Thanks!

Has anyone got the USBs working using instructions at https://www.digikey.com/eewiki/display/linuxonarm/STM32MP1 ?
I have tried both Ubuntu and Debian with no luck with USBs. I’m using DK2.
System starts fine with both OSs, but USBs don’t recognize anything connected to USBs, including USB-C. dmesg shows nothing when I connect USB memory to USB or USB-C port.

@Waldemar, sadly nothing in the 5.4.0-rc0 pull request:

https://git.kernel.org/pub/scm/linux/kernel/git/atorgue/stm32.git/log/?h=stm32-dt-for-v5.4

We should take a look at ST’s tree they used for the out of box image… Does anyone know which git tree they used for that?

Regards,

9

I’ll have to double-check my build script, but with the 10.1 minimal image, and latest u-boot and 5.4.0-armv7-lpae-x8 image, I’m not even getting a login prompt on the LCD anymore, and it’s not ever getting an Ethernet link LED. I suppose I shall have to hook up a serial terminal and see what it’s up to…

I didn’t get that far (I don’t think). Plugged up the STLINK port, and I’m not getting past the second u-boot signon. Although maybe it doesn’t use the STLINK port after that, not sure. Where are you connecting to get the output that you’ve got?

12

@jcwren, remove the “quiet” boot option from: /boot/extlinux/extlinux.conf and you’ll get farther… (log wise)

On the screen i do get two penguins…

stm32.jpg721×593 120 KB

I’ll start a git bisect run tonight to see what’s up…

13

I’m now getting as far as you are.

Apparently anything after the v2019.10 tagged branch of U-Boot is broken, and stops after the DRAM: 512MiB line is output, so that’s gonna be a future problem.

14

@jcwren, okay fixed the first issue… Turns out CONFIG_MMC_STM32_SDMMC has an indirect dependency on CONFIG_MMC_ARMMMCI… So once i moved CONFIG_MMC_ARMMMCI to built-in it just booted…

Regards,

15

wow that is mind blowing explanation I got solved my issue too… Thanks for that.

16

Seems like we’re a little further along. System boots, still no USB. But what I see now in the dmesg log is that vdd_usb is getting turned off. Haven’t yet figured out how to turn it on. Plugging a USB voltage analyzer definitely shows 5V isn’t present on the USB-A connectors.

Awesome, rebuilding the new kernel tree now. I had been fooling around for the past hour trying to merge in ST’s u-boot device-tree from the Yocto distro (which had a moderate number of differences) and had just getting ready to test it when the TechForum notification arrived. So the heck with that, I’m going with your changes :slight_smile:

Thanks for everything you do on this, BeagleBone stuff, and whatever other boards you’re involved in. You’ve been at this a long time, and your efforts and knowledge are greatly appreciated.

I’m getting this errors, no idea what might be the issue.
