i.MXRT QSPI boot

[sugiyamatoshihi]

Hi,

I have a question about QSPI boot of i.MXRT1050.

I checked Table 8-9. Fuse definition for Serial NOR over FlexSPI in reference manual, rev2 .

There is BOOT_CFG2[2:0] Device selection and QSPI description is only 111b column. 

Does it support QSPI by only BOOT_CFG2[2:0] =111?     

Does other BOOT_CFG2[2:0] =000 and 001 support for Single SPI mode?

Best Regards,

Sugiyama
