[beagleboard] Device tree: bind to alternate driver, or dummy entry?

2015-02-13 Thread sbattazzo
Hello, I have an alternate driver (xeno_16550A) that I would like to try to use for one UART while using the regular omap3-serial for all the others. Is there a way to specify in the device tree which driver to use? Alternately, could I have some kind of dummy entry in the device tree which

I'm not 100% sure about the 512MB of memory, but I suspect you'd be fine after the initial setup of the memory controller.. probably best to look at the memory controller section of the technical reference manual in order to figure that out. I don't imagine you'd have to deal with any virtual

[beagleboard] USB serial and USB network don't work on new Debian image?

2015-05-29 Thread sbattazzo
Hello all, I wanted to put a new Debian image on one of my Rev C BBBs that I have sitting around. It seems that the OS boots just fine now (LEDs are blinking as usual), but it's now showing up as Netchip Beaglebone Black when it was something else before (maybe Texas Instruments?) and I can't

[beagleboard] eMMC flasher?

2016-03-27 Thread sbattazzo
Hi guys, The new eMMC flasher images look very complicated compared to the old ones.. what's the story on that? The old one was very simple, just had a few files on it and it was easy to replace the .img.gz with your own and modify the script to use your filename. I've just downloaded the

[beagleboard] Spurious power button press with new Debian

2016-04-21 Thread sbattazzo
Hello guys, I have a custom carrier board powering my Beaglebone Black through the 5V supply pins on P9 (pins 5+6, I believe). Because I'm having issues getting my working legacy Angstrom distribution image cloned onto new boards that have Micron flash instead of Kingston, I decided to give a

[beagleboard] SPI disappears when cape plugged in?

2018-03-12 Thread sbattazzo
I have a Beaglebone Black with a recent Debian image that I loaded, we have some SPI hardware on one of those proto-board things, which works totally fine without the cape installed. Then we have pass through pins and a cell network modem cape sitting on top of that, which seems to work just

2018-03-28 Thread sbattazzo
Update if anyone's curious, I actually tried temporarily pulling the cape's corresponding overlay from /lib/firmware (I think that's where it was) and booting up that way, and SPI came back, so I believe that may solve my problem, otherwise I just have to modify and re-build that cape. -- For

[beagleboard] Re: SPI disappears when cape plugged in?

2018-03-21 Thread sbattazzo
OK, my possible understanding at this point is this: Cape EEPROM has a name string on it. BBB looks at that name string first and loads the matching file device tree. For some reason, no other device tree overlays are loaded. SPI is not a part of the overlay for this cape (confirmed by looking

Thanks for the reply, I believe I've already gone into the uEnv.txt and tried to explicitly do things like disable HDMI and enable the two SPI ports, (if I remember right I added those to "enable_partno=" or whatever the syntax was). But when I boot with the cape plugged in it seems to have no
