tx39 simulator timer questions

tx39 simulator timer questions

[Joel Sherrill]

Hi,

I hate to crosspost like this but I need to find someone who is
knowledgeable about the TX3904 and/or its simulator in gdb.  

I now have a simple RTEMS board support package (supports hello world)
running on it.  I want to use one of the 3 timers in interval mode 
to generate a clock tick. 

But between an error reading the PDF Toshiba documentation :)
and the simulator, I am confused about the requirements/sequence 
to make the timer do this.  Comments in dv-tx3904tmr.c indicate
that it does not support level triggered interrupts.

So far I have this as initialization:

  ILR3 = 0x00000700;  make timer0 level 7
  CCDR = 0x3;         divide by 16
  CPRA = <clicks>;    value in compare register
  TISR = 0x00;        clear all pending interrupts
  TCR  = 0xC0;        interval mode, internal system clock, enabled
  ITMR = 0x8001;      enable it, make it periodic

I think I may need to also deal with the CConR register.

??? What is the simulated clock speed when --board=jmr3904???
It is hard to know what is a meaningful value for CPRA.

I have tried to enable debug in the simulator (configured
with --enable-sim-debug) to see more of what was happening
but that resulted in gdb 5.0 not building.

Advice on the tx39 and/or the simulator is appreciated.

Thanks.

It may help if I clarify that this extension to the plain mips
simulator was done in order to let eCos run on it.  So, if you take a
look at how the eCos tx39 HAL talks to the hardware, and you copy the
relevant couple of lines, chances are that the sim will work
sufficiently well for RTEMS too.

I would like to thank Frank for his help.  I am now getting the 
clock tick and have console output working on the simulator.  

Here are a couple of things that are important to know about
this simulator:

  1.  configure for tx39*-* otherwise the tx39 device support
      and instruction set are not turned on.  [The mips simulator
      configuration is complicated because there are lots of 
      CPU models and ISA variations.]
  2.  The timer counts instructions.  

Frank.. does the simulator have a mode for an R4000 class CPU 
that supports the timer they have?

That, plus use the "--board=jmr3904" option to place the tx39
evaluation board's peripheral models into the address space.

None that I know of.

Smack your distributor until they give you a version of GDB that isn't
many years old?

Your cross compilers did not find libncurses on the target.  Either
the compilers are set up wrong, or you don't have the necessary
development files on your target filesystem to build GDB.

RE: Failed to build GDB-5.0

[Laxman Bana]

Thanks I found the answer by googling but now I have a problem at run time.
The symbol format is not able to recognize at runtime (forgot the error
message...something like dwarf_swp...). I am moving to gdb-6.0 now

-Thanks once again.
