I used u-boot-imx tree and this is what I get:
ls -al u-boot-dtb.imx
-rw-r--r-- 1 fabio fabio 547840 out 21 13:45 u-boot-dtb.imx
Original CONFIG_ENV_OFFSET is:
#define CONFIG_ENV_OFFSET (8 * SZ_64K)
CONFIG_ENV_OFFSET = 8 * 64 * 1024 = 524288
So the u-boot-dtb.imx is overlapping the env region.
Maybe your compiler is producing a smaller binary and you are not
getting the issue.
Anyway, it is safer to increase CONFIG_ENV_OFFSET and use
CONFIG_BOARD_SIZE_LIMIT to detect such problem in build-time.
