Hi,

do you know if there is a plan to extend this excellent article done by xinyu_chen

Run Zephyr on A55 with FRDM-IMX93 and FRDM-IMX91

adding support to FRDM-IMX91S?

Thanks

Hi @aspin

The package can support FRDM-IMX91S , it is very similar to FRDM-IMX91

Regards

Daniel

Hi Daniel,

I agree with you, I was just thinking about some few minor difference like the spi nand and the pmic.

Thanks

Yes thank you Daniel: do you have any advice about how to manage the spi nand?

Hi aspin:

Zephyr has built-in support for SPI NOR flash via the jedec, spi-nor compatible. But SPI NAND is not directly supported in the same way.

I found one NAND Flash project in Zephyr as below, it includes SPI communication logic and example handle implementation. maybe you can take it for reference

Hi Daniel,

I was thinking about the tool to write the Zephyr fw to the spi nand in the FRDM-IMX91S to be able to boot Zephyr.

Thanks
