Use the devil Jflash to burn and write FLASH in Linux

In Linux, use the devil Jflash to burn and write FLASH-general Linux technology-Linux programming and kernel information. The following is a detailed description. I tried to write flash in linux for several hours last night. I found a software package called Jflash through network search to achieve this function. I just watched a movie with no chance, when I saw more than and got up at, I suddenly thought about whether my VM didn't enable the parallel port, as if I didn't enable the serial port before, so I couldn't see the starting information, start the instance immediately. First open the VM and shut down it because my VM is suspended. Then VM --> Setting adds the Parallel port to start the instance, run the compiled software.

I will not introduce the Jflash software. As for the software package, we have downloaded the Jflash package from the previous website. In addition, the Jflash software package based on S3C2440 is downloaded from the Guangzhou friends arm, which is actually the same, because the cpu id is the same, first, the software package is downloaded, and then the following operations are performed:

[Root @ localhost root] # chmod + x your software package
[Root @ localhost root] # tar your software package
[Root @ localhost root] # cd your decompressed folder

Then modify your jtag. h file. For details about how to modify the file, refer to the second website I gave above. The first one is also acceptable, but it is not very detailed.

The preceding steps are not described in detail, because they were decompressed last night. What I did is:

[Root @ localhost root] # cd Jflash_s3c2410_linux/
[Root @ localhost Jflash_s3c2410_linux] # ls
Def. h jtag. h k9sxx08. o pin2410.o sbc_vivi
Jflash-s3c2410 jtag. o Makefile ppt. c sjf. c
Jflash_s3c2410_linux.bz2 k9sxx08. c pin2410.c ppt. h sjf. h
Jtag. c k9sxx08. h pin2410.h ppt. o sjf. o

// Next I run Jflash-s3c2410
[Root @ localhost Jflash_s3c2410_linux] #./Jflash-s3c2410

// Well, the speed is much slower than that of Sjflash in windows. It takes 10 minutes. No matter what, first check whether it can run, then return to the terminal, enter the serial port, reset the target board, haha, look at the following results, it is really good
