I got only .axf file from others. I have keil uvision and JTAG. my target device lpc23xx.how to flah axf file.?
You can use fromelf to get from a .AXF to a .HEX if you have tools for that.
For a ULink JTAG one of the techniques is to create a shell project for the specific chip, add in the flash algorithm for the part, and then copy a suitably named file into the output directory and use the Flash -> Download menu.
Other JTAG tools my have their own flashing software. An AXF file uses an ELF format.
Using an evaluation version of Keil, you can create a 'dummy' project with the same name as your .axf file (e.g. make a blinky.uvprojx for your blinky.axf file)

In the dummy project, under project -> Options for target -> debug tab, on the right side of the screen, choose your debug adapter. press the settings button to configure the device for connecting and flashing the device.
Press OK, to close the Debug adapter settings dialog. Press OK again to close the options for target dialog.
Select Flash-> Download to flash the device.
Keil supports multiple debug adapters, besides the ulink2.

rather than use the GUI to flash the device, you can call it from a command prompt. See:
