Problems stepping in CC and vector definitions

Started by thomas_hw_designer June 6, 2007
I've been given this new board to bring up. I see two problems (maybe
they're related).

The board features external RAM mapped from address 0. The DSP is
configured to run in Microprocessor mode for now during

debugging and just load directly to RAM from the XDS510USB JTAG
emulator. The connection to the board seems to be fine and I can
manipulate values in RAM.

1. I cannot step. Trying to step just increments the stack pointer
register but the program counter stays put

2. I try to build a simple project in Code Composer, but how should
the vectors (reset and others) be defined? I tried to define them as
an assembly file (see copy of the file below) but trying to compile
this assembly file gives a lot of errors (see build.log below)

Any idea what is going on and what I have missed..? The files I use
are posted below.

Best regards.

Thomas,

In assembly, the directives (e.g, .title), cannot start in the first
column. Insert tabs or spaces before these and you should be fine.

As for stepping, it sounds like your board is in reset. Is the PC
perhaps 0x45?
