[GitHub] [nuttx] TimJTi opened a new issue, #8325: RNDIS/CDC-ECM/CDC-NCM
TimJTi opened a new issue, #8325:
URL: https://github.com/apache/nuttx/issues/8325
I have been trying to get RNDIS working but cannot get it to connect to me Win11 machine. It won't connect to my Ubuntu 24.04 machine either. Creating this as an issue as per suggestion by @masayuki2009
CDC-ECM works with Ubuntu straight away but there are no built-in drivers for this with Windows so it is not an option right now.
Further investigation shows that RNDIS is likely to be deprecated from Linux in the near future anyway; @hartmannathan provided this link: https://www.phoronix.com/news/Linux-Disabling-RNDIS-Drivers
One solution might be to implement CDC-NCM (suggested by @michi-jung as that is then universal to Windows, Linux and Mac I believe?
Otherwise it looks like RNDIS is broken - unless anyone knows differently using recent NuttX builds, Windows and/or Linux?

> spresense:rndis and rndis_smp have been working fine with ubuntu 18.04 x86_64 on VMware Fusion.
With the defconfigs in the boards folders of the NuttX distribution or your own? I have been comparing my .config with the few in the distribution that have CONFIG_RNDIS=y and see no obvious differences. I tried RNDIS a year ago with Ubuntu 20.,04 and it didn't work then - so maybe there's a change since 18.04 and in later Windows builds that has broken NuttX RNDIS?
Initial investigations actually suggest an issue with arp requests failing - requests from my board don't seem to get out, and Windows doesn't seem to be sending any (but I'm a Wireshark newbie so may not be interpreting it right). I'm yet to try enabling DNS so perhaps that might be the key difference.

Thanks - means, even more so, that it's a question of my .config :( My hope is that it's down to not using DNS.

Found time to take a look and a (very close) variation of your fix above has sorted RNDIS for SAMA5 on both WIndows and Ubuntu.
Thank you VERY much @masayuki2009 :)
PR to follow.

@masayuki2009 Perfect! That's exactly what I believe to be going on, based on lots of evidence on other processors an RTOS'
I will try and implement similar fix and create a PR.

I've just installed ubuntu 22.04 x86_64 and confirmed that RNDIS works with spresense
So I think ubuntu 20.04 should work.

Thank you for taking the trouble to try this - I am using 22.04 so it has to be down to my .config. I have more things to try, now, and will report back what I did to fix it so hopefully others will benefit from my struggles!

A web search for that RNDIS_MSG_QUERY fail shows it has been seen by others on different boards and in different situations but still looking...but my belief is it is due to a combination of latest Ubuntu and Windows RNDIS drivers and a possible shortcoming of the SAMA5-specific usb device driver which is why I see it but stm32 users (for example) don't.

I think that there's something wrong with the SAMA5-specific USB driver.
Actually, when I tried to make USB RNDIS work with spresense, I had to fix the driver even it worked for Mass Storage.
You can find the fix as follows.
```
commit 06aa50e9bb255284a3fc286d466df8411a562148
Author: Masayuki Ishikawa <ma...@gmail.com>
Date: Thu Jun 13 05:40:03 2019 +0000
Merged in masayuki2009/nuttx.nuttx/rndis_on_spresense (pull request #895)
rndis on spresense
* arch/arm/src/cxd56xx: Fix ep0 out packet handling in cxd56_usbdev.c
This change fixes to handle ep0 out packet which exceeds EP0_MAXSIZE.
For example, 76 bytes of out packet is sent from rndis host during
rndis negotiation and finally the packet is split into two out packets
(64 bytes out packet + 12 bytes out packet). To handle these packets,
actual ep0reqlen is stored during ep0 out setup stage, and if all
out packets are received, it dispatches to cxd56_ep0setup(), otherwise,
it sets up the internal USB DMA to receive remaining out packets.
