Hello,

Customer faced problem to use the whole memory space of the MT35XU512ABA1G12 NOR OSPI Flash device.

We figured out that driver was configured to use by default 3-bytes addressing mode.

After changing the configuration (by enabling the definition of "EXT_ADDRESS_ENABLE" on the code level) the erase operation still uses the 3 bytes addressing mode, as per its implementation:

Do we support 4 byte addressing in SDR mode ? if not why EXT_ADDRESS_ENABLE redundant macro is still being used.

E2E reference:
