Hi All, I am new developer for Android platform, currently we are using iMX51 for our development. We changed codec chip form SGTL500C to Wolfson series, but the new driver is not ready yet. I found device will stop at animation logo if without audio driver support. Can I bypass this check and keep going remain boot-up process before audio driver ready?
