Hi Bruce, I believe the recipe for building Variscite’s kernel is in meta-variscite-imx/recipes-kernel/linux/linux-variscite_4.19.35.bb, which does produce a booting U-Boot and Linux image. What would

Hi Zoran, Thank you for responding. I confess I am still new to building Linux with Yocto, so some of your steps may seem obvious, but are a bit confusing to a 'newbie'. I am using normal Yocto instru

Hi Bruce, Yes, we are using Linux built by Yocto, but where is the preferred provider for the kernel set to linux-yocto-rt? Thanks for your help Scott D. Whitney sdw@... | T: 781-801-1152 | F: 78

Hi Yocto group, I’m working with a newly-released copy of Yocto Zeus from Variscite for the i.MX8MM Mini, although the same option seems to apply to the previous Yocto Warrior. I understand that a Lin

Thanks, Quentin, I'll take a look at Jozef's videos as time permits. Getting lots of time pressure to get something working, and even our SoM vendor provides examples that modify local.conf... so much

Thanks for the tip, Joel. I'm still new to this. How should libgpiod-dev be added to my local.conf? Do I just need to add it to EXTRA_IMAGE_FEATURES? Do I still need to add libgpiod to IMAGE_INSTALL_a

I should also note that gpioinfo and other tools from libgpiod run as expected on the target, and that /usr/lib has libgpiod.so.2 (libgpiod.so.2.1.1) in it. I would also like the header file to be put

I'm using Yocto Warrior 4.19.35 on a Variscite i.MX8M MINI SoM. I need to be able to respond to some interrupt events on GPIO events from userspace. I saw on kernel.org that the sysfs ABI is being dep

In Yocto Warrior, it appears that the default scheduler configuration is SCHED_NORMAL. We are trying to do some time-critical I/O, and it seems like we may be missing some data. I'd like to increase t

Dear Yocto community, I am hoping that you can provide advice on configuring UIO to handle a GPIO interrupt from user space. I found an excellent summary at https://yurovsky.github.io/2014/10/10/linux
