Touchscreen and GPIO Interrupt

Hi everyone, I'm running linux davinci on custom hardware with an AM1808. I got a problem to make working my touchscreen and gpio used as external interrupt together. My touchscreen alone is working well but when I add support for gpio used as external interrupt, the touchscreen is not work anym

Problem with UART1 on Davinci with OMAP-L138 ?

Hi, I'm trying to communication with UART1 on OMAP-L138. At the moment, I can write message to the serial port but I cannot read some. I got the error 11: Resource temporarily unavailable. To activate the UART1, I commented one line (see below) in board-da850-evm.c. I wonder what is "too much wor

Unhandled USB IRQ

Hi, I got this message when I disconnect usb key from my USB2.0 connector. *da8xx_interrupt 514: Unhandled USB IRQ 0028* I'm on OMAPL138 with custum hardware based on EVM. I'm using khilman tree Linux-2.6.34 with DA8xx glue layer and I modified my board specific files to add usb 2.0 support.

Todd, Is it possible that the problem occurs because the driver is using polling and it polls the PMIC to fast and it cannot handles all commands received so it returns NACK? Thanks Nicolas On Thu, Jul 29, 2010 at 8:24 AM, Nicolas Luna wrote: > Todd, > > Yes the polling is n

Re: Touchscreen - MFD driver for TPS6507x family

Todd, What do I need to change if I want to use the bitbang i2c driver and stop to get those error messages. I added support for "GPIO-based bitbaging I2C" into the kernel, anything else to change in the TPS driver source code? Thanks Regards, Nicolas On Wed, Jun 9, 2010 at 4:17 PM, Todd Fi
