pavgod Posted September 15, 2017 Posted September 15, 2017 Is there the support for hardware interrupts on pcDuino3nano gpio2(GPIO231) or gpio3(GPIO230) in Armbian mainline, as it worked on Lubuntu ? How can it be installed/enabled ?

It is already enabled : CONFIG_UIO=m CONFIG_UIO_PDRV_GENIRQ=m So, now it up to the application to use it or not ... How did you used it in your Lubuntu experience ? Googling "linux gpio interrupt example" will help you, for example, the second link will be : https://yurovsky.github.io/2014/10/10/linux-uio-gpio-interrupt/
Igor Posted September 15, 2017 Posted September 15, 2017 The same message was sent to my PM a few minutes ago and I am really getting pissed off on this kind of abuse. It's 3rd this week

Igor Posted September 15, 2017 Posted September 15, 2017 I am getting out if ideas how to stop this. Simply ignoring? Or replying in public with such stupid message? Wrote on mobile
martinayotte Posted September 15, 2017 Posted September 15, 2017 In my last week case, after trying to help a bit, I closed the PM thread by saying : BTW, why are you not posting this question to the forum, maybe someone help would be able to help ?

It's 3rd this week I am sorry to disturb you in such way. It goes only about question: is it available in Armbian's mainline and I'm missing smthg, or I have to patch .bts file in some way and recompile kernel. Once more, I'm sorry...
Igor Posted September 16, 2017 Posted September 16, 2017 6 hours ago, pavgod said: It goes only about question Quite the opposite. It's completely irrelevant what do you want. It's a trade for the time which is the far most expensive resource and for example, the one which I want to spend with my kids. Can your problem match this level? No. Can you buy time? No. I put this price tag/stupid answer, to keep people away from sending technical questions on email / PM. Is it possible for us to provide free one to one technical support for tens of thousands of users? It's mission impossible. A public forum is the best what is possible.

I used a temporary poor man's solution - timer interrupt and pooling hardware IRQ GPIO. But the problem still exists. Sorry, I'm not a kernel developer. I used this board (pcDuino3nano) in my project with preinstalled lubuntu, hardware interrupts (2 GPIO's) were supported in it. Now I migrated to Armbian because of lots of new features in it. I had to patch kernel to enable SPI support, I did it myself. But the hardware GPIO interrupts are not supported in Armbian in the old way. Looks, like I need to modify .dts file or smthg else, but I cannot do it myself without guidance or example at least . Any help is welcome.
