I am designing a custom imx6ul board that is configured to boot from eMMC - uSDHC2. Is there a way to disable booting from the usb_otg1 port if the eMMC boot fails? We would still need the serial boot functionality for development and production. I did not see any efuses that disabled usb port serial downloading.
Hi Rene
I am afraid this is not possible, available only fuse SDP_DISABLE
"Disable serial download support" described in Table 5-9. Fusemap Descriptions
Reference Manual.
Best regards

Igor,
SO setting the Disable Serial Download Support disables USB_OTG1 and UART1/2 downloads?
