Title: Can't boot Linux with GPS plugged in
Post by: milana on July 04, 2013, 02:49:23 AM

Hi,

I have A13 board with MOD-GPS. OS standard Debian image or jwischka R18.
I was able to read NMEA messages from GPS after I set ttyS0 speed to 19200 using cat > /dev/ttyS0.
But I have problem with booting while GPS plugged in. It is just not booting.

I have question about jwischka R18. Can I load usbserial module and where I can find it.
Where I can find sources and instructions if I need to build it myself?

Thanks.

Probably the GPS sends characters as the system starts so interrupts the boot. A bit like if you connect to ttyS0 and bang the enter key.

You can find the kernel to A10/A13 here: https://github.com/linux-sunxi/linux-sunxi (https://github.com/linux-sunxi/linux-sunxi)

Instructions to compile/build the kernel: http://linux-sunxi.org/Linux (http://linux-sunxi.org/Linux)

Enable CONFIG_USB_SERIAL to usbserial module.
