RT1064 : pin configuration to boot from internal flash

Hello,

This may sound as a dumb/noob question but I can't determine precisely what must be done on the BOOT_MODE1/BOOT_MODE0 and BT_CFG[11..0] pins to configure the RT1064 to boot from its internal flash memory.

Table 9.9 from the reference manual lists only 3 boot sources (NOR flash via FlexSPI, SDCARD and eMMC) but the internal flash is not listed, as if this section has been copied/pasted from RT1060...

AN12290 mentions a FlexSPI2 internal bus to this internal flash but does not indicate how to select it over the 3 above-mentionned boot sources.

Table 5 from the MIMXRT1060/1064 Evaluation Kit Board Hardware User's Guide indicates that 2 boot modes only are availble (QSPI or SDCARD) and also claims that QSPI boot is not available (note from 2.7 paragraph), leaving SDCARD as the sole boot source...


Any help greatly appreciated
