Hi guys, Im trying to interface a USB based GPS device on Beagleboard running Android eclair. I have connected the GPS device through a USB hub.
Everytime I connect the GPS device, i get the following msg on the console: it uses the USB-serial adapter pl2303 driver. when i connect the gps to the Beagle Board, I get a msg as: pl2303 1-2.4:1.0: pl2303 converter detected usb 1-2.4: pl2303 converter now attached to ttyUSB0 My goal is to get the NMEA data on the console or in a file. but on doing a cat /dev/ttyUSB0 i dont get the gps data. instead i get the following text which looks like some debug output: ------------[ cut here ]------------ WARNING: at drivers/usb/serial/usb-serial.c:376 serial_write_room +0x48/0x70() Modules linked in: omaplfb pvrsrvkm [<c0039934>] (unwind_backtrace+0x0/0xd8) from [<c005f09c>] (warn_slowpath_common+0x48/0x60) [<c005f09c>] (warn_slowpath_common+0x48/0x60) from [<c021cbe8>] (serial_write_room+0x48/0x70) [<c021cbe8>] (serial_write_room+0x48/0x70) from [<c01b57cc>] (tty_write_room+0x1c/0x20) [<c01b57cc>] (tty_write_room+0x1c/0x20) from [<c01b3204>] (process_echoes+0x3c/0x280) [<c01b3204>] (process_echoes+0x3c/0x280) from [<c01b51fc>] (n_tty_receive_buf+0xbc0/0x106c) [<c01b51fc>] (n_tty_receive_buf+0xbc0/0x106c) from [<c01b7688>] (flush_to_ldisc+0xd4/0x168) [<c01b7688>] (flush_to_ldisc+0xd4/0x168) from [<c006e230>] (worker_thread+0x150/0x1c4) [<c006e230>] (worker_thread+0x150/0x1c4) from [<c00711d4>] (kthread +0x78/0x80) [<c00711d4>] (kthread+0x78/0x80) from [<c0034e6c>] (kernel_thread_exit +0x0/0x8) ---[ end trace 5827570c12dafca5 ]--- ------------[ cut here ]------------ WARNING: at drivers/usb/serial/usb-serial.c:363 serial_write+0x6c/ 0xa0() Modules linked in: omaplfb pvrsrvkm [<c0039934>] (unwind_backtrace+0x0/0xd8) from [<c005f09c>] (warn_slowpath_common+0x48/0x60) [<c005f09c>] (warn_slowpath_common+0x48/0x60) from [<c021cc7c>] (serial_write+0x6c/0xa0) [<c021cc7c>] (serial_write+0x6c/0xa0) from [<c01b012c>] (tty_put_char +0x34/0x38) [<c01b012c>] (tty_put_char+0x34/0x38) from [<c01b314c>] (do_output_char +0x190/0x1c0) [<c01b314c>] (do_output_char+0x190/0x1c0) from [<c01b3394>] (process_echoes+0x1cc/0x280) [<c01b3394>] (process_echoes+0x1cc/0x280) from [<c01b51fc>] (n_tty_receive_buf+0xbc0/0x106c) [<c01b51fc>] (n_tty_receive_buf+0xbc0/0x106c) from [<c01b7688>] (flush_to_ldisc+0xd4/0x168) [<c01b7688>] (flush_to_ldisc+0xd4/0x168) from [<c006e230>] (worker_thread+0x150/0x1c4) [<c006e230>] (worker_thread+0x150/0x1c4) from [<c00711d4>] (kthread +0x78/0x80) [<c00711d4>] (kthread+0x78/0x80) from [<c0034e6c>] (kernel_thread_exit +0x0/0x8) ---[ end trace 5827570c12dafca6 ]--- There is a long loop of these messages. can any1 help?? -- unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting
