Dear Fabio,

The environment size has grown in such a way that it corrupts the main U-Boot image after a "saveenv" causing a U-Boot hang.
Fix this problem by increasing the CONFIG_ENV_OFFSET size.
Sorry, I can't understand this change.
/* FLASH and environment organization */ #define CONFIG_ENV_SIZE SZ_8K
-#define CONFIG_ENV_OFFSET (8 * SZ_64K) +#define CONFIG_ENV_OFFSET (12 * SZ_64K)
The size written to flash should never exceed CONFIG_ENV_SIZE; if it does, then there is some serious bug in the code, which I tend to doubt.
And when the environment grows,
This was V1. It is not the size of the environment, it is U-Boot that grows and has overflow into the environment, leading to corruption by the first saveenv.
Nevertheless, the initial offset (0x80000) was quite optimistic with current bootloader size - u-boot binary for i.MX is often > 512KB.
it would make it necessary to raise CONFIG_ENV_SIZE first
No.
- changing the CONFIG_ENV_OFFSET has nothing
to do with this per se.
Can you please explain which phenomenon you see, and hos this change is supposed to work?
Best regards, Stefano
