I own a quad core UDOO running debian wheezy - my setup: https://it.awroblew.biz/udoo/ Since I am not using any graphic intensive processes I would like to change the memory allocation. Right now I have 874MB of usable RAM so it looks that the integrated graphics has got the remaining 100MB+ How do I reclaim that for the OS to use? thanks A.
Hi alfwro13, to change the memory layout you need to change the U-Boot environment variables, setting a lower value to the gpu_memory option (default is 128M). If you aren't comfortable with connecting UDOO in serial with an external pc and modify the U-Boot variables manually I suggest you to download the attached file, extract in udoo debian system and install the .deb file with command: sudo dpkg -i udoo-config_2.1_all.deb this install our official UDOO Configuration Tool. Open the tool and navigate to the U-Boot section. Select "Reset U-Boot Environment" and after "Change RAM memory layout" to select the value you need. Once finished the procedure reboot the system and check the amount of RAM memory you have.
