Re: [beagleboard] Overlay does not create SPI pingroups with 4.4.21 kernel

Hi, I'm having an issue with a SPI device that works with Kernel 3.8. but not with the 4.4.x series. I have also tried the latest one 4.4.41-ti-r82. The device exists in both cases and I cannot think of a reason. Can you give me a hint what I might try to debug it? I tried the SPI loopback test

Re: [beagleboard] Overlay does not create SPI pingroups with 4.4.21 kernel

If you load overlays that are already included in your image, then you do not have to update the initramfs. But if you create your own custom overlay, it will not be included in the initramfs. On Thu, Dec 15, 2016 at 4:10 PM, Phil wrote: > Thanks for the info. I am not so

Re: [beagleboard] Overlay does not create SPI pingroups with 4.4.21 kernel

Thanks for the info. I am not so sure about the need to update initramfs though. Just for yuks, I specified my custom overlay in uEnv.txt, and it seems to have loaded properly, which I confirmed by inspecting the output of dmesg. I am still verifying that my SPI ports work as expected (phase

Re: [beagleboard] Overlay does not create SPI pingroups with 4.4.21 kernel

I am having almost the identical issue with SPI as pbft, except that I am running BBB's with *4.4.19-bone-rt-r13* and *4.4.38-bone-rt-r14*. I assume these can be fixed as per your suggestion, but it appears that the dtb-rebuilder is for the TI kernels only. Is this the case? If so, how should

Re: [beagleboard] Overlay does not create SPI pingroups with 4.4.21 kernel

Fixed and working - thanks for your help and your quick response. I *could* have banged my head against the wall a good deal longer on this one. It feels so good when you stop doing that. On Monday, October 3, 2016 at 4:58:55 PM UTC-4, RobertCNelson wrote: > > On Mon, Oct 3, 2016 at 3:54 PM,

Re: [beagleboard] Overlay does not create SPI pingroups with 4.4.21 kernel

Thanks. Love your work, by the way. Pretty near perfect for my needs. We have an open-source building control built on top of the BBB - we created the world's largest cape and stuffed it with industrial-grade I/O:

Killing me here - I'm running 4.4.21-ti-r45. Is it worth just getting the newer kernel? On Monday, October 3, 2016 at 4:52:45 PM UTC-4, RobertCNelson wrote: > > On Mon, Oct 3, 2016 at 3:46 PM, pbft > wrote: > > Thanks. I'm using your precompiled kernel, so I assume I

Thanks. I'm using your precompiled kernel, so I assume I checkout / download your 'dtb-rebuilder' and recompile the am335x dtb files that live in /boot/dtbs// - correct? > Disable the "edma-fix" it's causing spi issues in v4.4.x > > Just comment out it out like: > > >

[beagleboard] Overlay does not create SPI pingroups with 4.4.21 kernel

I have several overlays that I've been using with an earlier (4.1.10) kernel. In trying to port everything to a more recent kernel, my two SPI overlays don't create pingroups and don't set pinmux attributes. I've recompiled them using the dtc that came with the new kernel with no effect. They
