Keil uVision4 evaluation license [Tools]

Installation

You can download an evaluation version of the Keil uVision4 IDE from Keil's web site https://www.keil.com/demo/eval/c51.htm.

This evaluation version contains a fully functional 8051 compiler, assembler, linker, and debugger. The evaluation has a limitation of 2 kbytes object code, but by using the extended license as described below this limit can be increased to 4 kbytes.

Extending to 4 kbyte license

Nordic Semiconductor offers an extended evaluation version of Keil uVision3 as a part of the nRFgo SDK. With this version you can compile targets up to 4 kbytes of object code.

To extend the 2 kbyte evaluation version to 4 kbytes, open Keil uVision4 and go to File -> License Management. Click on 'Get LIC via Internet' to get a License ID. On the web page you will be asked for a Product Serial Number (PSN). Use the following serial number:

• SKAPZ-JRXUV-SBV97

You will receive the LIC code by email. Entering this code will enable the extended evaluation version.

Limitations

In addition to having an object code size limitation of 4 kbytes, the extended evaluation license does not support the Extended Linker and Assembler (LX51 and AX51). These must be disabled:

• Go to Options for Target ' '
• Un-check the boxes under Device Some projects use the linker keyword REMOVEUNUSED. This is not supported by the license and must be removed. You will get warnings about uncalled functions in the library. These warnings can be ignored.
