Clarification Required: QSPI Flash Capacity Mismatch Between Datasheet and Actual Hardware

Hello NXP Team,

I have purchased a board with the specified part number, and I noticed a discrepancy regarding the onboard QSPI flash capacity.

The datasheet states that the board includes 256 MB QSPI flash. However, when I check the flash size from the operating system, it reports only 32 MB.

To verify this, I downloaded the design files and checked the BOM. I also looked up the same flash device part number on DigiKey and Mouser, and both list it as 256 Mbit flash memory, which corresponds to 32 MB, not 256 MB.

I purchased the board through the Element14 distributor.

Could you please clarify whether:

The datasheet contains a typo and should state 256 Mbit instead of 256 MB?
Or is there another explanation for why the datasheet and the actual hardware appear to use different storage classifications?

From my investigation, it appears that the installed flash device is 256 Mbit (32 MB) rather than 256 MB.

I would appreciate your confirmation.

Thank you.

You are right, I will report it to related team, it is 256Mbit, that means 32MB.
