I am using SDCC 2.3. In SDCC 2.3, there is many different with SDCC 2.2.

I am trying to change location code at 0x2000.

When I compile my program with C with this command :

            sdcc -I..\share\sdcc\include   -code_loc 0x2000 timer.c

 After that, I read message below

            warning *** Only one short option can be specified at a time.  Rest of -code_loc


warning *** don't know what to do with file '0x2000'. file extension unsupported

 There are some warning at this message.

 Is message important ?

Can you help me to change location code at 0x2000 ?


Thank you for your help.
