Hi, Single binary image - The type of flash is not selected during compile time. The U-boot scans the flash available(as of now whether it is NAND or OneNAND) and starts using the first flash detected as the ENV storge. To select this option, I added a #define CONFIG_ENV_IS_RUNTIME_SEL(env storage selection during runtime).
