When upgrade to a new version of U-Boot, you also get a new version of mkimage. > If yes, I think I will upgrade. Where would you expect problems? You can build and test the new version of mkimage before updating the U-Boot image on your target board. And you can keep the old mkimage tool around for reference as well. > Of course, I understood that. My question was in the config file. I put this: > > #define CFG_ENV_SECT_SIZE SZ_16K > #define CFG_ENV_SIZE SZ_128K This makes no sense. I doubt that your NAND flash has 16 kB sectors. Also I seriously doubt that you need 128 kB for environment. > I saw something equivalent in the Evalution board of Davinci DM365 so it should not be > impossible. Please do not copy code without thinking.
