Problem with generating a single hex file for code banked application

Hi

My µC is C8051F122.

In µVision2 (version V2.40a and C51 V7.50) i create 2 Lib files. One for code bank 1 and one for the common bank.

These .lib files are linked into a project in Silicon Laboratories IDE. During to the .M51 file the code is located correct in the selected code bank.

I use BL51 linker and with OC51+OH51 i generate .H1, .H2 and .H3 files. Is there any way to create a single hex file instead? According to the Keil homepage it can be done by using HEX2BIN + BIN2HEX. Here i get an error (unable to open hexfile).
The file name is 1 character in length.

Then i tried to use the LX51 linker instead, but then i get the following error: L204 invalid keyword, POS 606 in one of the .lib files. When the error message appear a character in path is missing (please note that the path is identical to the one used when BL51 linker is used)

Any one with any ideas to creat either a single hex file from the 3 hex files, or how to get rid of the L204 error message when using LX51 linker?
