Inquiry Regarding W25M161AWEIT Flash Device on FRWY-LS1012A Evaluation Board

Dear NXP Team,

I hope this message finds you well.

I have a question regarding the FRWY-LS1012A evaluation board, which features the W25M161AWEIT flash device. As per my understanding, this flash device supports both QSPI NOR and QSPI NAND. We have successfully used the QSPI NOR to store U-Boot firmware and boot the board from it.

Currently, I have an OS image that is approximately 42 MB in size. I'd like to know if it's possible to store this OS in the NAND die of the W25M161AWEIT device. If so, could you please provide guidance on:

Flashing the OS to the QSPI NAND flash?
The memory-mapped address for accessing this NAND flash?

Additionally, I read in one of the documents that the board typically searches for an OS on the micro-SDHC card during boot. How can I configure the board to boot directly from the QSPI NAND instead of the micro-SDHC card?

Hoping for the reply as soon as possible.

Thank You

Our software (LSDK) does not suppport NAND flash at QSPI.

Hello Yiping,

Thank you for your response.

Could you please elaborate on this? Is it not possible to utilize the NAND portion of the W25M161AWEIT flash device?

It is impossible to use NAND portion of the W25M161AWEIT with LSDK, because LSDK doesn't provide QSPI NAND flash driver in u-boot and Linux Kernel.
