Hi all,
I've a ANTAP2DK1 Dev Kit here and I'm working on several different Linux distros. Kernel Versions are all 2.6 and above.
I've a very strange behavior using the USB-Stick ( lsusb = 0FCF:1006 Dynastream Innovations, Inc.) together with the chip AP281M51B.
Just to inform you: Connecting the ANT Chip via ANT I/O Board connected to a Pollin RS232-TTL works perfect with Linux.
So let me describe the issue I've with the USB-Stick. Maybe somebody can point me in the right direction.
- When the stick gets connected, the cp210x driver is loading and the device node /dev/ttyUSBx is created. (tried modprobe usbserial vendor=0x0FCF product=0x1006 too - but that's not working at all)
- If I connect with HTERM, a closed source terminal prog EVERYTHING IS FINE. I can send and receive commands as expected.
- Here's the strange thing: If I use any other terminal prog, no matter if it's minicom, cutecom or some self made prog parts e.g. based on termios I cannot achieve any communication.
- BUT imagine the following. If I start my program and then start HTERM and stop it right afterwards, it somehow activates something and now my program works as expected.
So I wonder what's HTERM doing, or what am I missing?
- So I compared the tty settings by doing a stty -a -F /dev/ttyUSBx while hterm is connected to my own settings. I adjusted everything so that they are similar. No success.
Did anybody have a similar issue and did maybe find a workaround based?
BTW you can reconstruct this issue when using the test_ant.gz example posted by markrages 2 months ago. (USB-Stick + AP281M51B)
Greetings and thank you,
Florian
