Re: [ECOS] Very strange: fis create/write fail Err = 92

["Xue weihua" <snowweihua at msn dot com>]

I use the command like "fis unlock -f 0x50040000 -l 0x100000".
I think it is good.because it is work on some sectors.

Yes,I have problem when I do "fis init",it say "Warning: device contents 
not erased, some blocks may not be usable".

maybe,my hw have problem,because it is new one.I have check it with our hw 
engineer and he
say he will help me check it.
