[C.CC USERS] Qs re occPlug's "Arduino" target and "Upload Firmware". *apologies; newb*

[Michael M. Butler]

I don't have any experience actually loading occam programs apart from
today. Skip to the bottom three questions if you wish. Thanks for your
time.

I am using Windows XP SP3; a Solarbotics "Ardweeny" is the target; my
FTDI interface shows up as COM11.

Arduino 0022 code loads and works as expected with "Board" specified
to be "Arduino Duemilanove or Nano w/ ATMega328". Code that is
supposed to blink the LED on pin13 does what I expect it to.

However, neither the "heartbeat" nor the explicit blink examples in
the Plumbing book appear to load and execute properly.

As a test, I first load code into the Ardweeny that fades an LED on
Pin9. This loads and executes as expected.

Then I exit the Arduino.cc dev environment and launch the Transputer one.

I open the ch2.occ code file. I start the occPlug.

I select Platform:Arduino, Device:Arduino and type COM11 in the Port:
field (no "pick" selections are displayed).

Compile completes successfully. I click the gear icon. I see data
apparently being transferred to the FTDI interface.

I see this in the occPlug text area:

==

avrdude.exe: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.02s

avrdude.exe: Device signature = 0x1e950f

avrdude.exe: 22678 bytes of flash written

avrdude.exe done.  Thank you.

Any output from the connected device will appear below
(hit stop to disconnect)

BUT the code that starts executing after the download has ended is the
old Arduino 0022 code I loaded, not the occam blink code--Pin13 shows
no activity.



Now, I note that occPlug has an "Upload Firmware" option. So I wonder...

1) do I need to execute this to change or supplant the extant
bootloader so it will execute the compiled .occ files?

2) if I do, what happens to my ability to use the target machine with
Arduino.cc's 0022 dev environment?

3) is this documented anywhere? I see no mention of it in the Plumbing book.
