Hello Wolfgang
Thanks for answering.
Good to see that mkimage would be ok with both versions.
What do I fear ? I traditionnaly saw many problems of version coherence
between binaries and tools generating them.
Now I prefer to ask.
Concerning the #define, I made a mistake when recopying.
this should be OK.
#define CFG_ENV_SECT_SIZE SZ_128K /* Env sector
Size = 128KB*/
#define CFG_ENV_SIZE SZ_128K /* 128KB is
1-Block size without counting spare*/
Concerning the size of 128KB. Obviously it is too much. I think it too. But
reading the README file, here is what I read:
Note: CFG_ENV_OFFSET and CFG_ENV_OFFSET_REDUND must be aligned
to a block boundary, and CFG_ENV_SIZE must be a multiple of
the NAND devices block size.
Since my sectors/blocks are 128KB, I must be at least 128KB!
Is the README file wrong ?
Thanks for your help.
Reda

Of course mkimage is not the same version. When upgrade to a new
version of U-Boot, you also get a new version of mkimage.

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.

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.

Please do not copy code without thinking.
