During the QNX/Linux development process on beagleboard, It is troublesome to connect to the beagleboard Development Board for each debugging. It is not difficult to connect to the Development Board, so you cannot bring it on a business trip. So we are going to simulate beagleboard on Ubuntu through a simulator. At first I found the
In Ubuntu, qemu is used to simulate beagleboard for QNX/Linux development on beagleboard. The trouble is that you need to connect to the beagleboard development board every time you debug it. it is difficult to connect various connections, and you cannot bring it on a business trip.

I bought the sbc8530 single-board machine of timll for development. The manual page says it is compatible with the beagleboard-XM interface. It is made according to the pictures of others. You can use it as needed. However, it is also a luxury to use it. network interfaces are not available. After you enter the system and run ifconfig, there is only one Lo, and no Nic can be found. The attempt to load the kernel through NFS and TFTP also fails. In U-b

Recently doing a thing that requires a large image to be JPEG compressed. BEAGLEBOARD-XM The default allocation of memory to the CMEM and DSP end Heap is not sufficient, and memory blocks need to be redistributed. Looked at the script for the memory allocation in the startup script and codec server, and quickly found the place to change.
1, the first need to modify is the startup parameters
The original startup parameters are:

Manufacturers to promote the LED backlight energy-saving, environmental protection is a gimmick Mody? LED LCD difference is it really that big? Together for you to unlock the
I. The era of ultra-thin flat display is approachingThe CRT (cathode ray tube) used by the TV has the disadvantages of large size, heavy weight, and limited size. With the development of electronic technology, there are more and more requirements for Mobile Display. the inherent limitations of CRT have hindered the miniaturization and mobility of CRT. This makes it more necessary to develop a new generation of display technology! The next generation of display focuses on a few points: the plane
