Chapter 5 Notes on Debugging

Page 5-8

5.3 Angel resources requirements introduce a number of

restrictions on application development under Angel.

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.

2. Do not modify the contents of the following registers with the Angel debugging monitor.

Address

0x400004

CKCON

0x600008

IRR0[3],IRR0[4],IRR0[5]

0x600012

ILCON2

0x600300

ASBUF

0x600301

ASIST

0x600302

ASICON

0x600303

ASBCON

0x600304

ASBTMC

0x600305

ASBTMR

0x600306

ASTSCON

0x600635

PFS5[6],PFS5[7]

0x600703

PWCON

For further details on these registers, refer to the ML670100 User's Manual.

3. Chain IRQ handlers.

If the application program uses IRQ interrupts, modify it to chain its IRQ handler to the

Angel debugging monitor counterpart with a procedure similar to the following.

Define a function Install_Handler() with two arguments: location, an address for storing the

entry address for the Angel debugging monitor's handler, and address, the address for the
