Thanks Stefan, great suggestion, I failed to copy those configurations into my original message.
/*----------------------------------------------------------------------- * DDR SDRAM *----------------------------------------------------------------------*/ #if !defined(CONFIG_NAND_U_BOOT) #define CONFIG_SPD_EEPROM 1 /* Use SPD EEPROM for setup */ #define CONFIG_DDR_ECC 1 /* with ECC support */ /* SPD i2c spd addresses */ #define SPD_EEPROM_ADDRESS {IIC0_DIMM0_ADDR} #define IIC0_DIMM0_ADDR 0x50 #define IIC0_DIMM1_ADDR 0x52 I am questioning my bus configurations... I haven't hooked up the scope yet, but I don't think data is hitting the bus. I don't see any areas to configure the I2C bus besides the board configuration file. Any suggestions? -- View this message in context: http://u-boot.10912.n7.nabble.com/PPC4XX-Custom-Board-Failing-to-read-I2C-tp151298p151427.html Sent from the U-Boot mailing list archive at Nabble.com. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
