Hi,

[COLOR=black][FONT=&quot]Q: Does NXP have or plan to design a seperate program - LPC flash programmer using LPC-LINK?[/FONT][/COLOR]
[COLOR=black][FONT=&quot]Or use ISP/IAP only?[/FONT][/COLOR]
In the next release of LPCXpresso, there will be a built-in flash programmer that uses LPC-Link. This will also be usable from the command line.

[COLOR=black][FONT=&quot]Q: Do IAR or MDK support with LPC-LINK now? Or planed?[/FONT][/COLOR]
You will have to ask them.

[COLOR=black][FONT=&quot]Q: For LPC chip programming, the final released binary file is .axf or .hex?[/FONT][/COLOR]
We can output in axf, bin, hex, srec.

[COLOR=black][FONT=&quot]Q: I checked some Make file, there may have commands to convert .axf create .hex file, am I right?[/FONT][/COLOR]
Yes. use the arm-none-eabi-objcopy command. See

[COLOR=black][FONT=&quot]Q: How to check final code/ram size for .axf file? [/FONT][/COLOR]

The example blinky application uses additional libraries such as CMSIS to demonstrate their use. If you use the libraries, this will obviously increase the code size. A minimal blinky can be done in about 200 bytes.

[COLOR=black][FONT=&quot]Q: For LPCXpresso IDE, how to Find/List keywords for all related files in whole project?
Use the Search->Search menu. You can search for text are for C/C++ keywords/identifiers

Sorry but I don't understand the question.
