A user-space device driver can do many of the things that kernel drivers can t, such as perform a long-running computation, block while waiting for an event, or READ files from the file system. Unlike kernel drivers, a user-space device driver can use other device drivers--that is, access the network, talk to a serial port, get interactive input from the user, pop up GUI windows, or READ from disks. User-space drivers implemented using FUSD can be much easier to debug it is impossible for them to crash the machine, are easily traceable using tools such as gdb, and can be killed and restarted without rebooting even if they become corrupted. FUSD drivers don t have to be in C--Perl, Python, or any other language that knows how to READ from and write to a file descriptor can work with FUSD. User-space drivers can be swapped out, whereas kernel drivers lock physical memory.

MTK flash TOOL源程序代碼 ========== FlashTool v3.1.05 (2007/05/15) ======= Bug fixes: 1. [DA] Fix that DA cannot be loaded on MT6225 for exceeding internal SRAM size. 2. [DA] Fix that NAND download/READ-back issue on MT6225 because buffer is linked on TCM. New features: 1. [DA] Supports new NOR Flash device [SPANSION] S29WS128P [SPANSION] S29WS256P [TOSHIBA] TV00560002DDGB 2. [DA] Supports OTP driver for below NOR Flash device [SPANSION] S29WS128P [SPANSION] S29WS256P Enhancements: 1. [DA] Provide Customized FlashTest_AllInOne_DA.bin. 2. [DA] NFB can auto format after first download. 3. [DA] Improve DA download algorithm: next sector will be erased only when a sector is fully programmed. 4. [DA] Improve DA download algorithm: enable recovery mechanism when press STOP button. 5. [DA] Improve MT6223 Download Speed.

java界面運行在pc上，write.c載到linux系統的節點上，兩者通過串口進行通信。然后在pc上運行test，在界面中輸入ttyUSB0,點open按鈕，然后點READ按鈕。接著在節點上./write運行write就能在界面上顯示接收到信息。

Run following Matlab commands to make sure the installation worked correctly. Unlike query function, filterdb does not load all waveforms to memory but returns filtered database object. This is useful when the resulting set of the query is too big to fit in memory. Consequent calls to READ function can be made to READ content of this filtered database object.

To write data to the FIFO, present the data to be written and assert the write enable. At the next rising edge of the clock, the data will be written. For every rising edge of the clock that the write enable is asserted, a piece of data is written into the FIFO. If the FIFO has data in it, the value at the head of the FIFO is present on the FIFO data output. To READ data from the FIFO, assert the READ enable. At the next rising edge of the clock, capture the data output the FIFO will subsequently advance to the next piece of data stored in the FIFO.
