Dear Expert:
How to change i.mx6ull qspi nor flash boot mode,such as 2-wire or 4-wire?
What is the default qspi nor flash boot mode?
In the i.mx-rt reference manual:
It seems nor-flash boot mode can change.
But in the i.mx6ull reference manual,there is not this content.
Please help ,thanks.
Hi Tom,
About the i.mx6ull qspi nor flash boot you can refer to the MCIMX6ULL-EVK_DESIGNFILES.

Dear Rita:

I mean that the irom bootloader of i.mx6ull,there is a basic configuration about nor-flash.
About this basic configuration,is that can change? What is the default configuration?
Hi Tom,
The i.MX RT is difference from i.MX6ULL, about the i.MX6ULL QSPI boot mode you can see details in 8.6.3 QuadSPI configuration parameters Table 8-23. QuadSPI configuration parameters.https://www.nxp.com/docs/en/reference-manual/IMX6ULLRM.pdf
