Hello all,
Recently TI has been promoting their new low power flagship processor,
the MSP430 by selling very cheap launchpads, that contain an
usb-connected board to program and test an MSP430. This board seems to
appear as two devices, a standard USB to serial port, managed by
cdc_acm, and a hid device, that actually implements ti's very own
spy-by-wire protocol and other oddities.(There are multiple toolkits
that can use that device fine)
The serial port allows easy communication with the device, but it seems
to be based on a TU4310 that does not always behave well with the linux
kernel cdc_acm part: by default the board comes programmed with a
chipset that just sends through the serial interface, 3 times per
second, a single byte that represents a temperature.
Once the ttyACM0 serial port is set to 2400baud and flow off(required
settings), usually a simple "stty 2400 -ixon</dev/ttyACM0" and cat, or
minicom, it does seem to give out the correct output.
However if one stops the minicom/cat, and waits a bit too long before
reopening it, the device seems to lock up, giving an i/o error for any
further operation, until it is unplugged and plugged again. From what I
can observe, it would seem TI's chipset has some sort of limited buffer
that fills up and then breaks. Catching up the buffer is of course
possible as long as it is still connected. I would assume TI's chipset
is guilty, but any suggestions/patches for a workaround to keep that
buffer empty/stop it from breaking/actually fixing the issue would be
welcome.
Thanks,
Paul-Kenji Cahier Furuya
