I have tested on a new imx6dl design but I can ask Dario to test on some other imx6 board, do I need to include it in the next release? I will send some other patches end of this week Michael > Thanks, > Peng -- Michael Nazzareno Trimarchi Co-Founder & Chief Executive Officer M. +39 347 913 2170 [email protected] __________________________________ Amarula Solutions BV Joop Geesinkweg 125, 1114 AB, Amsterdam, NL T. +31 (0)85 111 9172 [email protected] www.amarulasolutions.com
