Summary
Adds CDC ECM Ethernet over USB High Speed for SAMA5D36-Xplained
(and maybe other boards) (most of the code was there already,
but didn't work out of the box for the SAMA5D36-Xplained)
Only SAMA5D36-Xplained has been tested so far
Impact
None if you don't use the CDC ECM Ethernet driver
On SAMA5D36-Xplained, this adds high-speed Internet connectivity
over USB 2.0 High Speed. via the USB CDC ECM Gadget driver.
It may work on other boards too.
This also fixed full-speed (low-speed) mode for the board too.
Limitations
Hasn't been tested on anything other than SAMA5D36-Xplained board.
TODO
Ideally this would include a composite RNDIS device so it would
also work seamlessly on Windows. That is for a future PR
Ideally this would include software to help configuration via
mDNS/DNS-SD for plug and play compatibility with Linux and macOS.
That is for a future PR.
Detail
Only a few lines of C driver code needed to be changed, since the
capability was there already. The rest is config and documentation.
Changes the SAMA5D3-Xplained board bringup to match the SAMA5D3-EK
board bringup
A helper script to configure Linux routing and iptables NAT is also
provided, along with documentation on how to use it.
Testing
Manual, on a Ubuntu Linux 19.10 system and MacOS 10.14.6 Mojave
MacBook Pro.
How To Verify
Follow the new CDC ECM Ethernet over USB instructions in the board
README.txt file
Commits:
remove non-UTF-8 chars in comment and reformat
removed unneeded comment markers
instructions for using the defconfigs
removed EMAC from config
- to prove this example only needs the CDC ECM Ethernet over USB to work
added CDC-ECM Ethernet over USB info to README
added U-Boot image
added netusb helper script
- this can configure the Linux network interface and routes
so you can ping or access the NuttX system via TCP/IP.
renamed defconfig dirs to be ethernet-over-usb
- was usb-over-ethernet which is not right
added USB DMA to defconfigs
updated readme with autoboot and debugging info
bringing ethernet-over-usb examples into parity
added cdc ecm ethernet over usb with telnetd config
added defconfig
only use phy interrupt if netdevices is ethernet
- because now netdevice could be CDC ECM ethernet over usb
which has no PHY interrupt
add bringup to Makefile
add bringup
app init cleanup
init cdc ecm driver and rndis driver; some cleanup
fixed some typos and odd characters
