Hi ! Now im being able to get print on the serial console. My board is workin fine . its at91sam9261. the problem is something else. i have written a driver spi-new.c for the SPI interface using BUS 1 . now though this driver is getting compiled but its not getting executed when my board boots up . i have modified the following to u-boot source tree. 1) changed Makefile in /drivers/spi/ and added a line COBJS-$(CONFIG_ATMEL_SPI) +=spi-new.o 2) changed config file in /include/configs/at91sam9261ek.h added a line # CONFIG_ATMEL_SPI 1 though my init function is getting executed in the board file located at /board/atmel/at91sam9261ek/at91sam9261ek.c my driver code is not gettung executed when my board boots up. can anyone let me know where else to change to add a new driver in u-boot so tat ur board recognizes it. warm regards, Ravi Kulkarni.
