Can LOAD file to a specified memory area ?

"You mean, if I SAVE to SIM1.hex from a specified memory 0~0x1000 at first, then use LOAD will cause SIM1.hex load into 0~0x1000, because the hex file already include address information by SAVE. Is that your meaning ?"

Correct.

"How can I LOAD SIM1.hex into 0x0300~0x2000 not 0~0x1000 ?"

As I said, you would have to edit the Hex file.

Do you understand how Intel Hex files work?
There is a description here: http://www.keil.com/support/docs/1584.htm

The Hex file contains both data and the addresses at which to place that data.

"if I did LOAD hex file without address information"

There is no such thing - see above.

"Actually, I want to find a way out that I can load(read) my own bin file"

I don't think uVision supports loading BIN files - you can check in the Manual.

But you can convert a BIN file to HEX - see the links in the page I cited earlier.

"where is definition of S:, T:, U:, and V: ?"

It tells you they are user-defined - so you define them!

There are ready-made tools available for this purpose - some of them are even available for free, like "srecord". They can also do the address manipulation for you.

"There are ready-made tools available for this purpose - some of them are even available for free"

And some included with the Keil tools!
Of course, the Link describes the Keil ones.

Thank you very much, Andy.

I had used BIN2HEX to convert the bin file to be a hex file, and I LOAD it into memory in uVision2 command window successfully.

But it got a error while loading the hex file with big size. I set the starting address is 0x3000, and the hex file size is around 10MB. uVision2 feedback a error message "error 57: illegal address:0x00FFFF".

I guess it is that loading 10MB hex file get over 64KB address defintion, because loading 3KB hex file doesn't.

How can I solve it?

BR,

"I guess it is that loading 10MB hex file get over 64KB address defintion"

Of course it does!

"How can I solve it?"

Don't attempt to load files that are too big!!
