IMX6UL USB_OTG1 Boot Disable

[renedebacker]

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.

Igor,

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