I'm using the cosmic c tools version 4.4.22 (for the Freescale 9S12 MCU) and would like to be able to link MY OWN libraries to banked segments. I am thinking that if I compile the code that goes into the libraries with the +modf option, all functions will then be "far" and I can locate them in banked segments. However, I am not sure what technique to use in the linker command file (.lkf file) to place libraries in specific banks. For example, will this work: # PIX = 38 +seg .ftext -b 0xe0000 -o 0x08000 -m 0x4000 -w 0x4000 -n Page0 -s CODE # Page 0 of banked code PPAGE=0x38 mylib.a if I just want to put the whole library in one segment? Do I have the option of locating the individual functions in the library to different segments? If so, what's the syntax? # PIX = 38 +seg .ftext -b 0xe0000 -o 0x08000 -m 0x4000 -w 0x4000 -n Page0 -s CODE # Page 0 of banked code PPAGE=0x38 mylib.a:myfunction1 # PIX = 30 +seg .ftext -b 0xe4000 -o 0x08400 -m 0x4000 -w 0x4000 -n Page1 -s CODE # Page 1 of banked code PPAGE=0x39 mylib.a:myfunction2 or somesuch? -- Randy Yates Digital Signal Labs http://www.digitalsignallabs.com
