Hi all,
This is the problems I having...
The usb dongle gets picked up by linux and the /dev/ttyUSB0 gets created. I
can start the msp430-gdbproxy and even connect and debug. Problems start
after I detach the msp430-gdb or close the proxy. I then start getting the
following error messages.
debug: MSP430_Initialize()
error: msp430: Could not initialize device interface (1)
Unplugging the dongle and replacing it also gives the above errors when
starting msp430-gdbproxy even though the /dev/ttyUSB0 is created.
I then tried `cat /dev/ttyUSB0` and I get the following error
cat: /dev/ttyUSB0: Input/output error
There are no unusual errors in dmesg or in /var/log/messages
It seems to crash the entire USB serial stack. Even plugging in a FTDI USB
serial dongle gives the same `cat` error. Unloading the ti_usb_3410_5052
module, also has no effect. I have to restart the PC to get it all working
again.
All this seems to happen on Gentoo kernel 2.6.28-tuxonice-r3
I've tried the dongle on Ubuntu 8.10 with kernel 2.6.27-11-generic and it
works perfectly, no errors with reconnecting or multiple runs of the proxy.
I've diff'ed the ti_usb_3410_5052.c and .h files between kernel
2.6.28-tuxonice-r3 and 2.6.27-11-generic and there is no real difference
between the two versions.
Anyone else having problems like this? Any solutions?
