pkg/tinyusb: add tinyUSB netdev driver #18903

gschorcht · 2022-11-14T07:16:46Z

Contribution description

This PR adds the tinyUSB netdev driver.

The tinyUSB netdev driver is part of the tinyUSB package and is enabled by module tinyusb_netdev. It is available for boards that provide the tinyusb_device feature.

Please note Since the tinyUSB package is distinct from (and incompatible with) the USB stack provided around USBUS in RIOT (see USB), the tinyUSB netdev driver cannot be used together with with any USBUS device class.

The tinyUSB netdev driver uses Ethernet over USB and supports the following protocols:

CDC ECM (Ethernet Control Model)
CDC NCM (Network Control Model)
RNDIS (Microsoft Remote NDIS)

While Linux and macOS support all these protocols, Microsoft Windows only supports the RNDIS protocol and since Windows version 11 also the CDC NCM protocol. macOS supports the RNDIS protocol since version 10.15 (Catalina).

Which protocol is used is selected by the corresponding pseudomodules tinyusb_class_net_cdc_ecm, tinyusb_class_net_cdc_ncm and tinyusb_class_net_rndis.

The CDC ECM protocol (tinyusb_class_net_cdc_ecm) and the RNDIS protocol (tinyusb_class_net_rndis) can be used simultaneously to support all operating systems, for example :

USEMODULE='tinyusb_netdev tinyusb_class_net_rndis tinyusb_class_net_cdc_ecm' \
BOARD=... make -C ... flash

In this case, the CDC ECM protocol is the default protocol and the RNDIS protocol the alternative protocol defined as second device configuration. The CDC NCM protocol cannot be used together with the CDC ECM or the RNDIS protocol.

This PR includes PR #18983 for now to be compilable.

Comparison with USBUS CDC ECM (nucleo-f767zi board):

  63120	    544	  15444	  79108	  13504	tests_usbus_cdc_ecm.elf

Testing procedure

Use a board that is supported by tinyUSB. Compile and flash the test application for each protocol:

RNDIS

BOARD=... make -j8 -C tests/pkg_tinyusb_netdev flash

CDC ECM

CLASS=tinyusb_class_net_cdc_ecm BOARD=... make -j8 -C tests/pkg_tinyusb_netdev flash

CDC NCM

CLASS=tinyusb_class_net_cdc_ncm BOARD=... make -j8 -C tests/pkg_tinyusb_netdev flash

For each test, a network interface should be added on the host. Use command ifconfig on USB device and on the host and check that both have a link local address. In syslog there should be an output like the following:

Needs a rebase now, I'll try to give this a look soon.

dylad · 2023-01-19T19:56:31Z

I just tested it on stm32f429i-disco, samr21-xpro and same54-xpro.
A RNDIS interface is mounted and I was able to ping both side for all boards.
I didn't have time yet to look the code in details.

dylad · 2023-01-24T20:32:09Z

Feels free to rebase.

I've noticed a weird artifact in lsusb for RNDIS only (see UNRECOGNIZED):

These bytes are part of the interface descriptor as generated by the tinyUSB RNDIS Descriptor Template macro:

  /* CDC-ACM Header */\
  5, TUSB_DESC_CS_INTERFACE, CDC_FUNC_DESC_HEADER, U16_TO_U8S_LE(0x0110),\
  /* CDC Call Management */\
  5, TUSB_DESC_CS_INTERFACE, CDC_FUNC_DESC_CALL_MANAGEMENT, 0, (uint8_t)((_itfnum) + 1),\
  /* ACM */\
  4, TUSB_DESC_CS_INTERFACE, CDC_FUNC_DESC_ABSTRACT_CONTROL_MANAGEMENT, 0,\
  /* CDC Union */\
  5, TUSB_DESC_CS_INTERFACE, CDC_FUNC_DESC_UNION, _itfnum, (uint8_t)((_itfnum) + 1),\

Either the macro is incorrect or the descriptor is not decoded correctly by the Linux kernel driver. I would tend to the latter. But either way, I'm afraid there's not much we can do to fix it.

gschorcht · 2023-01-31T23:55:34Z

I have rebased the PR to resolve the conflicts. I have also provided some small fixes.

dylad · 2023-02-01T07:55:57Z

I'll re-test tonight.

dylad · 2023-02-01T20:54:27Z

Please squash.

dylad · 2023-02-01T20:58:58Z

Either the macro is incorrect or the descriptor is not decoded correctly by the Linux kernel driver.

Looks like TinyUSB changes the class/subclass/protocol trio because of Windows (probably for compatibility reason ?)

#if 0
/* Windows XP */
#define TUD_RNDIS_ITF_CLASS    TUSB_CLASS_CDC
#define TUD_RNDIS_ITF_SUBCLASS CDC_COMM_SUBCLASS_ABSTRACT_CONTROL_MODEL
#define TUD_RNDIS_ITF_PROTOCOL 0xFF /* CDC_COMM_PROTOCOL_MICROSOFT_RNDIS */
#else
/* Windows 7+ */
#define TUD_RNDIS_ITF_CLASS    TUSB_CLASS_WIRELESS_CONTROLLER
#define TUD_RNDIS_ITF_SUBCLASS 0x01
#define TUD_RNDIS_ITF_PROTOCOL 0x03
#endif

Linux is happy with Windows XP value but not with the default value. I guess there is nothing we can do on our side for this.

RNDIS is primarily intended for use under Windows so I think we can accept the problem in Linux.

RNDIS is primarily intended for use under Windows so I think we can accept the problem in Linux.

I guess so. I'll give it a try on a Windows laptop tonight.
If we're all good, let's merge it tonight.

@gschorcht
Were you able to test RNDIS on a Windows host on your side ?
The only windows laptop I have, has a picky USB...
Just want to make sure that's my laptop fault.

gschorcht · 2023-02-03T08:34:22Z

Were you able to test RNDIS on a Windows host on your side ?

I don't have any native Windows system. I tested it with my VirtualBox Windows 10. It seems to work.

main(): This is RIOT! (Version: 2023.04-devel-240-gee8dc-pkg/tinyusb_netdev)

This test pulls in parts of the GNRC network stack, use the
provided shell commands (i.e. ifconfig, ping) to interact with
the tinyUSB based network interface.
