Subject: LCDVSYNC not set up in Atmel AT91SAM9RL device code
Date: Mon, 23 May 2011 14:53:27 -0600 [thread overview]
Message-ID: <4DDAC947.7040705@usask.ca> (raw)
Hello,
I've been setting up an LCD display interfaced to the Atmel AT91SAM9RL
processor, and I noticed that in the
/arch/arm/mach-at91/at91sam9rl_devices.c file, the GPIO pin AT91_PIN_PC4
is not switched over to the LCD peripheral.
To make the LCD display peripheral operate properly, I had to add the
following line to the at91_add_device_lcdc() function:
at91_set_A_periph(AT91_PIN_PC4, 0); /* LCDVSYNC */
Perhaps this could be patched? I do not know if a similar issue also
occurs in other device setup files.
Nicholas
