# CONFIG_USB_FUNCTIONFS is not set #43
Comments
This should be fixed in the kernel. |
Shouldn't this be |

configfs is different that functionfs (we need both).
|
poking - makes me think it could be either
or
|
that's my sentiment as well; however i can't say for sure yet that we don't need |
I just tried R5 of the release on RPi 4, and it still isn't there...
functionfs is still missing, configfs is there.
|
same on Zynq 7000 (it's not there)
|
ok, but are you sure that here's what i get for a ZC706 with the current kernel, and this is :
i can't seem to see any devices via USB cable yet with iio-osciloscope
I may need to see if also, this USB/OTG context seems to have been mostly used on Pluto and M2k and not much else; if i search in the DTs for Zynq I get:
so, PackRF seems to have needed this, but I'm not sure when this was last tested, or if this was tested; also, in the picture above, i'm not sure if it's worth touching it, since it's under legacy; and is a mess to enable it; [1]

a question after the previous reply is:
we can do it for the next releases; |
seems to be a bug with Ubuntu's libiio-dev;
we could probably open a bug report; but we'll see; |
Yes.
No. Like you said - it was done for a few platforms, but there was no consistency. This would improve the end user experience alot (IMHO). (no IP numbers to configure) - we get requests for this. |
last I checked debian was not installing the udev rule. |
Xilinx ships broken USB Micro B to Female USB A Adapters in their kits. So enabling OTG mode by default for Xilinx carriers is causing lot's of support issues. HOST mode can fail. So plugging in a keyboard no longer works. |
Ok. The new This issue was about the Kconfig symbol; that seems to have been solved. |
Enabling OTG mode - and allowing it to be self selected by the ID pin - I agree will cause issues. Enabling OTG in the kernel, and providing two device trees (host mode, and device mode) should be easy (in theory)? and better than we have today... ? |
michael@mhenneri-D06:~/devel/hdl/github-linux-work/linux/arch/arm/boot/dts$ grep dr_mode zynq* michael@mhenneri-D06:~/devel/hdl/github-linux-work/linux/arch/arm/boot/dts$ ls zynq*.dts | wc This will double the device trees we have today.. |
Ok - I can pretty quickly make a script that decompiles device tree...
uses sed to search replace and recompliles/replaces for the next boot (if that's easier). |
That's definitely the preferred option. An alternative would be to use u-boot fdt utils to patch the dtb during boot. |
an overlay would be interesting; we might be approaching a point where the Linux master tree could run on RPi as well; on a broader topic, overlays would be interesting because we could simplify our DTs;
the only issue i see, is that some new device-tree compilers issue more warnings than older ones; |
a uEnv.txt option, or |

functionfs
isn't in the kernel, or a module, so I can't get usb gadget going with IIO.The text was updated successfully, but these errors were encountered:
