What I find is *VERY* helpful when trying to understand flash control issues is to *manually* do the QRY write sequence (see your flash data sheet) by using memory write/read commands from the u-boot command prompt I tested the same using "mw" and "md" commands from uboot prompt for read CFI query command. But test failed.
Log details: mw 0xfc000000 0xf0 mw 0xfc000055 0x98 md 0xfc000010
Please make sure to use the byte commands instead:
=> mw.b 0xfc000000 0xf0 => mw.b 0xfc000055 0x98 => md.b 0xfc000010
Otherwise you will access the FLASH 32bit wise. Please re-check with this version.
