I have used code banking. please let us know the step by step by instruction to dump the code in device f130.

I have followed the below steps but i could not get success in it.
1) converted mycode.omf into mycode.hex using OH51.exe
2) FlashUtilCL.exe Download mycode.hex 1 0 0

"1) converted mycode.omf into mycode.hex using OH51.exe"

Which linker do you use?
BL51 - OC51
LX51 - OHX51

- OH51 hex converter doesn't support banked code.
- Separate HEX file is generated for each bank

"Using OC51" for BL51 from Keil
"Code Banking" for LX51 from Keil

"2) FlashUtilCL.exe Download mycode.hex 1 0 0"

FlashUtilCL.exe Download mycode.b00 1 0 0
FlashUtilCL.exe Download -B1 mycode.b01 1 0 0
FlashUtilCL.exe Download -B2 mycode.b02 1 0 0
FlashUtilCL.exe Download -B3 mycode.b03 1 0 0

"with OC51 it has generated mycode.b01, mycode.02. mycode.b03 files for B1,2,3, but i didnt find mycode.b00."

Umm..
- OC51 generates separated object files for each bank. These output files must be converted to HEX file by OH51
- The each object file generated by OC51 includes "common code", that is, BANK 0. Another split procedure is required; It is done by an utility, like SRecord.

SRecord - win32
http://sourceforge.net/project/showfiles.php?group_id=72866

Then, the procedure is revised as follows.

1) OC51 - Convert original banked-omf file into separated-object files of each bank

> OC51 mycode.omf

mycode.B01, mycode.B02, mycode.B03 are generated.
- When the original banked-object file doesn't have corresponding bank, separated-object file isn't generated for the bank.

2) OH51 - Convert each separated-object file to HEX file

> OH51 mycode.B01 HEX (mycode_B01.hex)

3) Srecord - Split "common" part and banked part

For Bank 0,
> srec_cat mycode_B01.hex -intel -crop 0x0000 0x8000 -o mycode_B00.hex -intel

For other banks,
> srec_cat mycode_B01.hex -intel -crop 0x8000 0x0000 -o mycode_B01.hex -intel

4) FlashUtilCl - Write them to the FLASH

> FlashUtilCL.exe Download mycode_B00.hex 1 0 0
> FlashUtilCL.exe Download -B1 mycode_B01.hex 1 0 0
