We need to set it with the default value at the beginning of the processing or to raise an error if we want to make this statement mandatory in the configuration file. Best regards, Stefano Babic

What do you think would be a default value? The one for SD boot? The one for NAND? Or?

If there can't be a default value, I think to raise an error if no BOOT_FROM statement is there is the only option. Best regards Dirk

This is desirable, but it does not correspond to the code. > What do > you think would be a default value? The one for SD boot? The one for > NAND? Or? Who will decide what the default should be? Whatever we choose, it is wrong. We can select SD, and one board has not a SD interface. The same with NAND, ... The best one is we have not a default value. > >> at the beginning of the >> processing or to raise an error if we want to make this statement >> mandatory in the configuration file. > > If there can't be a default value, I think to raise an error if no > BOOT_FROM statement is there is the only option. Agree - BOOT_FROM must be mandatory. Best regards, Stefano

The flash header v2 supports different flash offsets for different boot devices. E.g. parallel NOR or OneNAND use a different offset than FLASH_OFFSET_STANDARD (== 0x400). The flash offset is correctly read from the configuration in parse_cfg_cmd(). But is then overwritten wrongly in set_imx_hdr_v2(). Fix this by removing this overwriting. Use the flash offset correclty read from the configuration, instead.
