After successful installation, there are two things: jlink and jflash.

 

I failed to connect with j-link, but it was successfully installed in j-flash.

However, there are prerequisites for successful connection in jflash:

Click file open project S3C2440. jflash (if there is no such file, the http://download.csdn.net/detail/shaellancelot/5138635)

Click option, project settings, CPU (ARM), and make the following changes:

 

CPU:
Core --> ARM9. Little endian

Use target RAM (faster) --> Addr: 40000000 4KB (not selected very slowly; the address and size of the internal Boot SRAM when the Nor flash is started, refer to the S3C2440A chip manual)

Modify the following content on this page.
