[E3-hacking] PBL response

[Matt Evans]

Dear Ralph,

Today I tried your 'exp' program with my setup.  How come it's so 
well-written in that it prints debug for EVERY termios option under the 
sun??  ;-))  (I mean, I had to comment half of them out to get it to 
compile on darwin ;)

Appended is its output;  from what I can tell it should be 
SENDING_ESCS, then get an ack, then send packets for opcodes 0 and 2 - 
these are "get version" or something?  (I don't have your list to hand, 
in a rush unfort.)

Anyway, having sorted out my serial woes (minicom) I've sent it a bunch 
of escs and seen the expected
006 006 006 006 006 006 006 006 006 006 006 006 006 006 006 response.  
Then I thought I'd try 'exp' and see what happens;  it moves to this 
CS_HAVE_ACK state a bunch of times - I'm guessing because it gets 006 
16 times as the wakeup code print_strings a line of them.  Then it just 
sits there doing nowt.  I'll take a closer look later on but just 
thought I'd let you know.  :)

(Other observation re WDT:  Quite a long timeout, you said 4-5 secs but 
I observed about 15secs after having got the acks before the reboot.  
Also, I see the WDT being initialised at 0x280.  WDTCTRL gets set to 
0x67; this is WDT on, resetting, 2^29 clock ticks.  (This is about 1s 
at 50MHz - my 15sec timeout must be a different timeout?)  Also I 
haven't seen the FRZ (WDT freeze, lock-on) bit being set ever... is it 
set somewhere else?)


Cheers,



Matt
