[beagleboard] Re: Enabling SPI1 on BBGW via DeviceTree (no capemanager)

As stated in the first post, I've tested it on 4.9 and 4.4, resulting in same behaviour on both. I've fully disabled mcasp in my .dtsi: { status = "disabled"; }; but it didn't work. This may be due to the board being BBGW not BBB/BBBW - I've already encountered few other things that

[beagleboard] BB Blue reliability

Thanks for all the details, John. I'll look into that approach when I get around to more serious kernel programming. Right now, I just want to figure out why this example isn't working for me. I need to download Robert's header files for the BBB to my host. If I just add a file to

Hi, John - thanks for the reply. I don't believe, however, that I'll need to use JTAG, at least not for this specific example. Here's my current thinking: I already have a cross-development platform (Qt Creator) set up for the BBB, so I'm going to try to use it to build kernel modules. I know

Re: [beagleboard] which "arch" subdirectory to use?

You need a kernel aware JTAG debugger like Lauterbach. This will allow you to debug u-boot, kernel code, including all the drivers as they are loaded, etc. It is expensive, but it is the gold standard for kernel/driver debugging. TI have Code Composer Studio that will do some debugging of the

[beagleboard] Re: Enabling SPI1 on BBGW via DeviceTree (no capemanager)

I had a similar issue with 4.9 kernel where I couldnt load SPI1 pins using BB-SPIDEV1. Apparently mcasp was also getting assigned the same pins, disabling audio in uEnv helps. Didnt really test it all the way, but I could see /dev/spidev* pins loaded and spidev module loaded. Hope this help,

[beagleboard] Re: Enabling SPI1 on BBGW via DeviceTree (no capemanager)

Problem "solved" (worked around really) by switching to SPI0, changing the pins around and rerouting most of our custom cape. There are still some problems with the SPI bus but that's a separate issue. -- For more options, visit http://beagleboard.org/discuss --- You received this message
