i.MX6DL - Determine Boot From Recovery Device

christian_neuwi — Fri, 14 Oct 2016 12:58:41 GMT

Hi,

we're building our own hardware based on an i.MX6DL using an eMMC as primary boot device and an SPI NOR Flash as recovery device.

Our board behaves as expected when there is no bootloader in eMMC, i.e. it boots from SPI NOR Flash, but I can find no indication about that fact in any of the SRC registers I've been looking at.

Is there such an indication at all and - if so - where can I find it?

Regards,

Chris.

Hi Chris

I am afraid there is no such indication which recovery device was used.

FYI:

The flag PERSIST_SECONDARY_BOOT (SRC_GPR10[30]) does indicate that booting occurred from the recovery device. It might not say exactly which recovery device was used, but since you can have only one that information is usually good enough for the firmware to react appropriately if needed.

Best regards,

Chris.
