But it needs to be added to the project files. Note: The entry “PXAG49” in EDE|XA Assembler Options\Preprocessing configures controller ports P1, P2 as well as P3.6 and P3.7 as push- pull (see the Philips PXAG49 Data Sheet for details on port configuration). © PHYTEC Meßtechnik GmbH 2002 L-481e_4...
Page 87: Linking And Locating
In addition, the linker must locate several segments of code and data to fixed address locations within the address space in regards to the memory types of the phyCORE-PXAG49. XDAT segments always must be located to Random Access Memory (e.g. RAM), CODE segments should be located to non-volatile memory (e.g.
Page 88 For instance all XDAT segments should end below 0x3FFFF if a 256 kByte RAM device mounted on the phyCORE-PXAG49. We recommend generation of a *.map file for your project and inspection of the memory map information within this file.
