[Skyeye-developer] help simulating at91 timer

[josh jordan]

I am trying to get timer0 to work to count cycles in simulation.  Here
is some debug output:

p/x pTC0
$1 = 0xfffa0000
p/x *pTC0
$2 = {TC_CCR = 0x21, TC_CMR = 0x80000000, Reserved0 = {0x0, 0x0},
TC_CV = 0x0, TC_RA = 0x0, TC_RB = 0x0, TC_RC = 0x0, TC_SR = 0x0,
TC_IER = 0x0, TC_IDR = 0x0, TC_IMR = 0x0}

it recognizes the pTC0 pointer with the correct address.  It decodes
the struct.  But the values of the struct are stuck.  My program
assigns other values to them but they always read as above.  Even when
I try to change it like pTC0->TC_CCR=1 that has no effect either.
pTC0->TC_CV always reads zero!

It looks like the source code updates timers, I am just not using it correctly.

Here is my conf file, trimmed down most everything commented.
