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 U…

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. [ 0.363462] usbcore: registered new interface driver usbfs [ 0.363534] usbcore: registere…

@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,

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. dmes…

@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,

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 u…

@jcwren , yeah it’s locking up:; Found /boot/extlinux/extlinux.conf Retrieving file: /boot/extlinux/extlinux.conf 268 bytes read in 5 ms (51.8 KiB/s) 1: Linux 5.4.0-armv7-lpae-x8 Retrieving file: /boot/vmlinuz-5.4.0-armv7-lpae-x8 10990080 bytes read in 468 ms (22.4 MiB/s) append: console=ttySTM0,11…

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?

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