Hi Saida

1. seems dp83848 is already integrated on some i.MX6 boards, like fs-net PicoMODA9 board

2. lwip was in i.MX6 SDK, if you previously got it, then one can find it in sdk/lwip directory

(also please find attached this part ).

3. this is defined in uboot/include/configs/ files, #define CONFIG_ENV_IS_IN_FLASH.

For example one can look at mx6sabre_common.h

Best regards

igor
