I have patched board/ti/am335x/board.c and mux.c. I have used am335x_evm config that I have had to patch somewhat to suit my board. Board resembles somewhat am335x_evm but it does not have configuration eeprom, has different ddr3 chips. Also, it has different PMIC (same as beaglebone). Therefore I need to patch guite a lot. One reason why I2C configuration is wrong in nand mode could be the fact that I have CONFIG_TI_I2C_BOARD_DETECT variable is undefined (because I do not have that eeprom). But it looks that do_board_detect runs enable_i2c0_pin_mux() that I do not run separately. On the other hand, that does not explain why mmc boot works. > > Thanks and regards, > Lokesh > _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
