USB driver for Raspberry Pi
-
Hi there,
I'm trying to have the M5Stack products communicating by USB with my Raspberry PI.
I've tried using the source package from https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/drivers/CP210x_VCP_Linux.zip.
I unzip the file, I have a .tar.gz file, I gaip -d it, got a tar. When doing a tar xvf on it, I have some error messages (tar: Ignoring unknown extended header keyword 'SCHILY.dev' for instance).
I have only few files, including a Makefile, but when I run the make command, I have :
make -C /lib/modules/uname -r/build M=/home/pi/Downloads/toto modules
make[1]: *** /lib/modules/4.19.66-v7+/build: No such file or directory. Stop.
Makefile:7: recipe for target 'all' failed
make: *** [all] Error 2I've also tried directly connected my M5Stack device, but I have the following lines in my /var/log/messages, and there's not serial port available:

How can we have the USB communication working with the Raspberry Pi ? -
I'll answer myself ;-)
I copied the /lib/udev/rules.d/69-libmtp.rules to /etc/udev/rules.d, added the line
ATTR{idVendor}=="0403", ATTR{idProduct}=="6001", GOTO="libmtp_rules_end"
That prevents the M5 devices to be recognized as MTP devices.
Then they're recognized as Serial ports, and Arduino IDE can access them.So we don't need the driver, just a change in udev configuration.

Oh cool, thats for working out how to do this. I can continue my plans of adding an RPI to my project bench to programme the M5Stacks and Sticks.
Thanks you.
