Cyclone IV E remote update +epcs+cfi_flash

the problem has been solved!

In my c code, I use 'alt_write_flash_block ' API.

my flash is 8M , consist of two regions. region0's block_size is 8192-bytes;

region1's block_size is 65536-bytes;

in the past, i operate region0 and region1 with 65536-bytes, so the error like my description occur.

The right method should be:

operate region0 with 8192-bytes;

operate region1 with 65536-bytes;

That's all, thank you!
