imx7 dual recovery boot

Hi,

 

we are in the process of designing a system based on an i.MX7 dual.

The default boot device is an eMMC flash. I also would like to use the SPI recovery boot option but i'm a bit confused on how it is configured. As far as i understand the device detects a broken image on the primary boot device and then uses the SPI flash for recovery.

For this i have to set BOOT_CFG4[6] to 1. So far so clear, but i also have to configure BOOT_CFG[11..9] to boot from SPI which will prevent boot from eMMC!?

Could you please clarify this.

 

Best reagrds,

Ralf
