Hi , I am newbie to the u-boot loader. I have one external CPLD which has connected to processor via spi protocol. My requirement is to support CPLD from u-boot (eg:- read registers and write registers etc)
Could you please help me ,how to follow the steps to implement this functionality. I have gone through the mailing list , as expert suggested add the CONFIG_SPI,CONFIG_HARD_SPI to hardware specific config file. i have done the changes i couldn't resolve the issue. I am using U-Boot 2009.08. SPI lines are connected at PORTH register. i have configured the port H for other functionality (SPI Driver). processor <---> PORTH <---------> CPLD/FPGA thanks for your help Manohar.K
