PCBUG11 fails Communication

Started by micro controller March 18, 2005

Hi to all,

I'm using PCBUG11 to program a 68HC11A1P.
But the program fails to communicate with the chip. I tried connecting XIRQ to Rx, with PCbug11.exe -xA port=1 on the
command line.
And connecting XIRQ to Vdd via a 90 ohm resistor, with PCbug11.exe -
A port=1 on the command line.

Both don't work.

In these two cases, when Pcbug11 enters, I typed
control timeout 4000 ( I also tried 40000)
then CTRL R ( I also tried the restart and restart -xE options)
but it keeps telling Communication Failed!!

So I doubted about the COM1 on my PC, and I tried a Java program
with the MAX232 having Tx and Rx ( on the TTL side ) tied together,
and I received every byte I sent...

What's left ? the chip ? I tried WinBug11 and JBug11 and another
program too. In WinBug11 and JBug11, I got an error when loading
the .s19 (actually forgot in which program :$).
In another program (French interface, I think it's test mic11), it
read the chip successfully, and successfully loaded the monitor into
the chip -- as it said. But I didn't know how to load an .s19 using
this program....

Possible Hardware connection error:
DB-9 pin 1 (DTR): Is this pin critical when using MAX232 ?
I tried connecting it to the other unused Rx on the MAX232, then NOT
CONNECTED, then to GND via a 5Kohm resistor ('cause I saw that the
MAX232 has a 5K resistor to GND on its Rx input, and the
corresponding Tx output is unused...)

It's really disappointing having to try all combinations without
success!! :(:(:(

Are there recommendations/check ups that can help ?
Thanks in advance,
Roger Tannous.

Hi

I do have these problems. It is because the processor chip os too fast that the program Pcbug11 cannot be used on fast processor. Later i used Winbug and Jcbug11. Winbug can be used on winNT or win98. Sometime it oso give communication error. Jcbug11 i didnt try as i oso give me problem on communication error,

It is either you used PC of processor 486 or slower; Or you can try using Xload or MicroLoad to download to you microcontroller. they are both available in the website of technological arts.

good luck on trying,

Regards

HuiChen,

The PC is a Pentium IV with 1GB or RAM.

Should a big value used in

CONTROL TIMEOUT bigValueHere

solve the problem even if the PC is relatively fast? I tried many big values but the problem was not solved.
So I doubt about the chips now. Is there any way to detect whether
the SCI interface is defective while "spying" on the data flow that
the MCU sends to a PCbug11 session ? Does anyone have an idea about
this ?

This is what I thought I can do, I can send the data sent from the
MCU to the COM Port ( finally reaching PCbug11 software ) to another
Port ( on my PC, I have the Parallel Port left, unless I use USB
which is not possible for the time being 'cause I don't know details
about the USB protocol ) and display and save that data and compare
it to a known-good version :)

Can anyone help please ?

Best Regards,
Roger Tannous.
