[i.MX8M PLUS] Missing information about GPIO boot overrides

[iderzh]

Hello,

I'm using latest reference manual iMX_8M_Plus_RM_RevC.pdf.

The 6.1.3.2 "GPIO boot overrides" chapter doesn't contain information regarding eFuse override configuration by GPIOs for eMMC/SPI NOR boot parameters as referred in chapter  6.1.5.5.1 table 6-23 and  chapter  6.1.5.6.1 table 6-27.

Please help to find missing information.

Hello,

   the BOOT_MODE[3:0] balls and internal fuses control boot. 
No more pins, except BOOT_MODE[3:0], are involved here.
  Customers can refer to i.MX 8M Plus LPDDR4 EVK Board Hardware User's Guide
for more details regarding BOOT_MODE[3:0] settings.
 

   Note: i.MX8MP documentation is still under working.

Regards,
Yuri.

Hello Yuri,

Thank you for reply!

I have to complete my HW design, but uncertainty with GPIO straps is blocking me.

Could you at least provide updated information about GPIOs with eFuse override functionality.

I'll implement provisions in my design.

Best Regards,

Igor
