Re: [U-Boot] driving a serial peripheral in u-boot

Dear "Dexdyne Postmaster",

In message <memo.20090811100117.12188B@postmaster+dexdyne.com.cix.co.uk> you wrote:

Our AVR32 board has a GSM modem attached..

I'd like to send an SMS at power-on, though if we successfully boot Linux it will do more sophisticated stuff.

If we get the SMS, then nothing further we know the boot failed.

Is there an example anywhere of u-boot talking to a device on a serial port ( which is not the console ) I can use as an example?

See common/modem.c and search the code for mdm_init().

Best regards,

Wolfgang Denk
