22:28 <Martinv> Hi everyone; new Yocto user here. I am using Digi Embedded Yocto which I believe is a Yocto supra-layer. There is a lot to learn and right now I'm trying to work out who I should be asking - the Yocto users, or Digi directly. My problem is...

22:30 <Martinv> I have built an image successfully, so all good. Now I want to customise part of it which I have learnt is in a thing called a device tree overlay. I have found this overlay in my tmp build hierarchy. I suspect I could change it here and see the result, but this would be temporary until the next build (?) so I need to find where the file

22:30 <Martinv> originally resides (I think?) and modify it there. But I cannot find the file anywhere else outside tmp. Is this a Yocto question, or a quirestion for Digi?

22:39 <paulbarker> Martinv: You'll need to find which recipe is responsible for the device tree overlay and then check the recipe to see where it gets its sources from

22:40 <paulbarker> If you've got support from a vendor definitely take advantage of it and ask them

22:40 <paulbarker> The Yocto community is very welcoming though and folks will try to answer questions on here or on the mailing lists if they can

22:41 <paulbarker> You're likely to get more response during US/Europe working hours

23:01 <Martinv> paulbarker: finding the recipe makes sense. I'll try and see if I can do that. If I don't have luck I'll try Digi directly; their helpdesk has been helpful so far regarding some other firmware questions I had. Thanks for your help. Good idea regarding the timezone too.
