I successfully installed mspgcc in Fedora 10, using RPMs from :
http://xgoat.com/wp/2008/12/13/mspgcc-rpms-for-f10/

after I changed FET430UIF driver name as indicated from:
http://xgoat.com/wp/2008/11/26/uif-firmware-breakage/

F10 can successfully detect the FET430UIF and attached /dev/ttyUSB0 to it
but the problem is I couldnot update the firmware in FET430UIF with this:
su -c "msp430-gdbproxy msp430 --update-usb-fet /dev/ttyUSB0"

it reported errors:
notice: msp430: TI USB FET update requested
notice: msp430: Initializing bootloader…
notice: msp430: Erasing interrupt vectors…
notice: msp430: Erasing interrupt vectors…
notice: msp430: Erasing interrupt vectors…
error: msp430: Could not initialize device interface (1)

with dmesg command it reported:
ti_usb_3410_5052 2-1:2.0: TI USB 3410 1 port adapter converter detected
usb 2-1: TI USB 3410 1 port adapter converter now attached to ttyUSB0

usb 2-1: ti_write_byte - failed, -110

I am not familar with linux environment. Why I use it under linux is because I am using a opensource project and what a emacs utilities.
I can successfully do it under windows both with a virtual machine with VMfusion2 under Mac OS X.

SO, could anybody help with this?
