I asked our flash team, unfortunately, they said that due to SFDP on octaflash not existing from beginning, therefore, some old parts may not support the SFDP parameter inside the Flash. For MX66LM1G45G, we have SFDP available from 2020/03. However, other flash maybe meet the same problem, I will update them later. As for ID conflicts, I will discuss with them which series of flash has encountered this problem, and I will update it later.
