I've developed our custom board based on iMX6UL and I've a question about workaround suggest in Chip errata, ERR009455:
what happen if the pin XTAL IN is left floating (point 1) ) without connecting a 18pF load? Does the iMX6UL boot up correctly?
Reading the IMX6ULHDG document, it seems that a capacitor in the XTALIN pin is needed only for filtering.
Thanks in advance
