Dear colleagues. My partners and me work with “Udoo quad”. We would like to work with all available com (UART) ports. There are five known available to use com ports[1]. Provided sources [2] say that by default three com ports are available. We try to rebuild linux kernel according to manuals [3, 4] in order to enable other com ports. Also udoo forum with solution of this problem [5] was used. But we can`t find specified files to change them. Search by function name in linux sources also didn`t give any results. What can be done to unlock all com ports? [1] manual UDOO_Starting_Manual_beta0.4_11_28_2013 [6.1] [2] http://www.udoo.org/downloads/ [3] http://www.udoo.org/docs/Advanced_Setup/Compile_The_Linux_Kernel_And_The_Modules.html [4] manual UDOO_Starting_Manual_beta0.4_11_28_2013 and forum [5] http://www.udoo.org/forum/threads/solved-enabling-serial-ports.1457/ P.S. If I have downloaded the latest UDOObuntu (v2rc1)from http://www.udoo.org/downloads/ I have solved the problem with com ports using “device tree editor”. But I met some problems when I try to transfer my project to UDOObuntu (v2rc1): 1. The board doesn’t recognize any monitor and resolution is minimal and couldn’t be changed, it seems that the board is working without video driver. 2. Unlike previous version UDOOboard 12 “Pulse audio volume control” doesn`t allow me to change mode of “imx-vt1613-audio” to “Duplex” (only “Input” or “Output” are available). 3. UDOObuntu is used pulseaudio 4.0.Our project is based on pulseaudio 1.1 and can`t be rewritten. All these problems mean that I need to use UDOObuntu 12 version with enabled UART3 and UART5. But I don`t know how to turn them on.
Hi there, have you checked UDOObuntu 2 RC2? You're still using Kernel 12.04. Instead we've moved to 14.04, and there's some new function to easily do what you want (speaking about the Device Tree Editor).
