Programmers developing application programs using the Angel debugging monitor should keep the following in mind. 1. Specify the default (0x8000) as the loader address using the following linker syntax. armlink -R0 0x8000 Do not specify the address 0x0 because the Angel debugging monitor requires addresses 0x0 to 0x3c to load the application program.
