USB device stack #3890

jfischer-no · 2015-09-17T21:33:30Z

USB Device stack implementation for RIOT.

Description:
It's all still WIP but it works. As it says in the title, it is a USB Device stack. It means that a RIOT board with this stack can communicate with the USB host.

For now, only the Kinetis Driver (8bef8ab) exists. It would be great if someone would add a different platform. Possibly the interface between driver and stack needs to be expanded.

Hardware Driver and Stack use few macros and need only few changes in Makefile. The Driver uses a "driver_init" macro to register at the stack, similar to module_init in Linux. It (dc8a7c9) still needs a little fine-tuning. And I hope you find it useful (I do not like the RIOTs autostart).

To be continued....

Supported and boards (SoCs):

Freescale Kinetis (tested with kw22d512 and k64f)
Boards pba-d-01 and frdm-k64f

How to test:

pba-d-01 : The board needs to be slightly modified, a bridge and a capacitor. Instructions follow. The board should be populated with the kw22d512
frdm-k64f should work without problems

Under test/usbdev (8db566c) is the appropriate Makefile. For testing you can either do
./dist/tools/pyterm/pyterm --port /dev/ttyACM1

Depends on ~~#4114~~, #4163 and serves as an example for #4155

More good news today! Thanks!

@jfischer-phytec-iot, nice to see your PR. Currently, a USB stack is a big lacks in RIOT imho.
I'm currently writing the support for NXP LPC11U34, a USB CortexM0 MCU. A usb stack would really be appreciable.
Once I've finished the implementations of the peripherals for this MCU, I'll try to implement your USB stack and see how it works.

@jfischer-phytec-iot

I do not like the RIOTs autostart

Could you elaborate on this? Perhaps it is possible to improve the autostart system?

jfischer-no · 2015-10-05T11:44:36Z

@ks156 Well, when the time comes, I'll help you gladly.

@gebart I will separate the commit dc8a7c9 and explain my concept, it is similar to that in the Linux kernel.

jfischer-no · 2015-11-05T16:12:11Z

If someone wants to test it with the PhyNode Boards version 1426.0 or 1426.1, the following modifications must be performed:

two 0402 resistors (20Ohm ... 30Ohm) must be populated
100 nF capacitor between pins PTE 18 (D14) and GND
connect PTE19 (D15) with VCC3V3

New 1426.2 Boards do not need this modifications.

The PhyWave module should be populated with MKW22D.
I have now tested it with gnrc_border_route example and it works mostly very good (a2a9440).
Over second USB connector (besides Phytec logo) runs the communication with the border router.

I got usb working on samr21-xpro, this PR will be rebased and updated in the next days.

kaspar030 · 2016-02-02T11:27:12Z

nice! very looking forward...

PeterKietzmann · 2016-03-23T13:41:03Z

This PR is WIP and I assume we won't make it until the release. Removing the Milstone now. Feel free to reset I was wrong in my assumption.

kYc0o · 2016-07-25T14:07:53Z

WIP -> postponed. And please rebase if possible.

miri64 · 2016-10-31T14:42:43Z

Postponed due to feature freeze.

OlegHahm · 2017-01-15T10:07:32Z

Let's remove the milestone until someone has time to pick it up again.

antmerlino · 2017-01-21T15:55:13Z

@OlegHahm What is the status of this? How close was it to being done? Is anyone familiar with what has been completed already and could walk me through some of it?

I can't make any promises but depending on the level of work, I'd be interested in helping finish it. I would like to get a shell working over USB CDC ultimately.

jfischer-no · 2017-01-23T10:22:05Z

Total outdated, update will come

aabadie · 2017-10-08T11:05:37Z

@jfischer-phytec-iot, this PR is very interesting for some SAMD21 based boards (Arduino MKR, Adafruit Feather). In this comment above, you said that you could make it work on Samr21-xpro which kind of samd21 based. Is there any chance that you update your branch soon or give some notes on how you achieved this ? (We might consider reopening this PR I think)

jfischer-no · 2017-10-10T08:06:15Z

@aabadie yes, I have tested it with samr21 board. I have to look again and squash so that it looks reasonable. Would you like to work on the usb device stack? I will unfortunately not have much time to help and I do not want that only the samr/d driver will be maintained, as it indicates in your message.

dylad · 2017-10-13T20:34:51Z

@jfischer-phytec-iot Your work is really interesting ! It would be great if you can reopen or share your branch. I'd would love to help RIOT to have a full USB support someday :)

aabadie · 2017-10-14T21:57:39Z

@dylad, if you are interested in working on this, you can fetch the branch reference by the PR:

git fetch upstream pull/3890/head:wip@usbdev
git checkout wip@usbdev

dylad · 2017-10-15T10:30:05Z

Thanks for the tip @aabadie !

jfischer-no · 2017-10-16T14:59:44Z

@dylad This PR can not be reopen, please pick wip@usbdev branch from my repository

maribu · 2020-06-04T09:04:49Z

This PR is still referred in the mulle board documentation. Is that reference still up to date?

Let's try to summon @bergzand, he might know.

dylad · 2024-05-06T08:36:09Z

This PR is no longer relevant regarding USB support for RIOT. I think it was added there as a "TODO" to add USB support later. I think you can remove it.
Sadly there is no periph_usbdev AFAIK for kinetis. But maybe tinyUSB could be use instead ?

bergzand · 2024-05-06T08:50:45Z

Let's try to summon @bergzand, he might know.

I don't think this PR was on my radar while working on the USB stack.
