For most i.MX31 boards TEXT_BASE is > 0x87f00000. That was the point. Now I'm able to boot u-boot out of the RAM. It's working well but I have some issues. I can ping my linux host and I'm able to download a binary file via TFTP into RAM. But I'm not able to ping the boad with u-boot from my linux host. In my config-file I defined CONFIG_NETMASK and CONFIG_IPADDR. What could be wrong? Another strange thing is the nand driver. I build my u-boot with: #define CONFIG_MX31_NAND 1 #define CONFIG_CMD_NAND #define CONFIG_SYS_NO_FLASH 1 #define CONFIG_ENV_IS_IN_NAND 1 #define CONFIG_SYS_NAND_BASE CS0_BASE #define CONFIG_SYS_MAX_NAND_DEVICE 1 #define CONFIG_SYS_NAND_MAX_CHIPS 1 If I then try to get "flinfo" information u-boot jumps to the next command line and prints nothing. If I try "nand info" I get information about nand device 0. Another strange thing is that I can't read from nand flash but I can write. Do you have any suggestions? Thanks.
