DM355EVM + tsc2007 touchscreen driver error

Other Parts Discussed in Thread: TSC2007

Hi everyone,

I'm working on DM355EVM with 2.6.10_mvl401 kernel. I  tried to add touch screen driver and created tsc2007.ko and tsdev.ko. However I can't introduce tsc2007 to DM355.

When I run these modules I got below errors :

 

root@192:~#  insmod  /lib/modules/2.6.10_mvl401/kernel/drivers/input/touchscreen/ tsc2007.ko

DaVinci I2C WARNING: i2c: NACK detected
DaVinci I2C WARNING: i2c: NACK detected
DaVinci I2C WARNING: i2c: NACK detected
DaVinci I2C WARNING: i2c: NACK detected

root@192:~#  insmod /lib/modules/2.6.10_mvl401/kernel/drivers/input/  tsdev.ko

ts: Compaq touchscreen protocol output

What may be the reason of these errors?

 

Regards,
