hi,everyone~~~
i use s29gl032a(model 4) as my norflash on my nios system.when i test the norflash with the memory test code,it can only recongnize 8 blocks and 8KB per block whick is just the bottom boot sector of the norflash.why it can not recongnize the uniform sector whick is 63 blcoks,64kB per block large. is there anything wrong with nios accessing the top boot sector? because i can not run my c program normally when power on,is the reason why it failed to boot from norflash? it troubles me a lot. thanks all in advance. looking forward to you answering me.Link Copied

I can't find a data sheet for s29gl032a but most devices have commands that you write in your software to protect and unprotect region or sectors of the device.
