The CFI query is normal for a x16 device: byte address 0xAA is word address 0x55, which is what is expected from a x16 device in x8 mode as in x16 mode.
Can you try a 'md.b 0x1f400020 20' once in CFI QRY mode?
Amicalement,
You mean like this?

No, I meant the instruction exactly as I quoted it: 'md.b 0x1f400020 20' once in CFI QRY mode, that is:
mw.b 0x1f400000 0xf0 mw.b 0x1f4000AA 0x98 md.b 0x1f400020 20
