AM5728: 32MB QSPI flash access

Part Number: AM5728

Hi,

Our customers have 32Mbytes of QSPI FLASH in CS1 of QSPI.

They selected CS1 in memory mapped mode and read the contents of QSPI FLASH,
It will be as follows.

① 0x5C000000 - 0x5CFFFFFF → CS1 data can be read normally.
② 0x5D000000 - 0x5DFFFFFF → The same data as ① is read.
③ 0x5E000000 - 0x5EFFFFFF → The same data as ① is read.
④ 0x5F000000 - 0x5FFFFFFF → The same data as ① is read.

QSPI FLASH has 32Mbytes, so they want to read the data after 16Mbytes at the address of ②.
Is there a setting that can read the correct value?
Or is it not necessary to set up 32Mbytes of access possible?

Best Regards,
Shigehiro Tsuda
