Zilog Z8 Encore XP help

[Mark Harriss]

Hi again,
I finally got around to installing the package on my XP machine. I
plugged the USB adaptor into what I'm pretty sure is a USB 2.0 socket,
installed the driver and it all worked OK.
I changed the jumper settings to set up the "User" mode had a bit
of a play with the ZDS, and managed to unintentionally overwrite the
demo program in the micro with an example one which just blinks one
LED, so it appears to all be working.
I think I now have a rather steep learning curve to get used to the
extra instructions and things on the chip. It's a bit hard to know
what to do with an 8 pin micro....
I hope you can find out why your USB cables don't want to talk to
your PCs. Once the ZDS is running, it all seems to work pretty well.
Good luck.

Regards,
Bob

Ok Bob: the final solution for me was to get into my motherboard
BIOS and set it to USB 1.1 from 2.0 and it all worked fine from there on
in. If I had to suspect something I would say it's the motherboard
drivers, I also flashed a new copy of the motherboard BIOS as the maker
mentioned a USB locking up fix in the BIOS but that didn't help in this
case.

I don't have any other USB 2.0 peripherals to see if it's a problem
with the computer.

Hi People,
I recently bought a Z8 Encore XP
microcontrolled dev kit and I'm having
proglems with establishing a connection with
the board itself so I can program the Flash.

i'm using a USB smartcable/dongle to connect
to the board but I'm having trouble finding
setup documentation for jumper settings on the
development board

Can anyone give a few pointers to relevant
docs or directly help me?.

Regards
Mark H

Hope you didn't pay more than $9.95US for the kit:

Just noticed it on Sonars front page.
I know Zilog have always had some of the cheapest dev kits going
around, but this time they are practically giving them away. Guess it's
obvious why!

For what you get, at that price it's a steal! Yesterday I installed
the Zilog software on my work PC (the new 3GHz P4 which was bought in
desperation to try and make Protel 99SE behave), and I had no problems
getting the USB driver loaded and running the Zilog Development Suite.
I'm just sorry that Mark's having so much trouble with the one he
bought. He did later say that he found the jumper setting
documentation. From looking at the included schematic, it's not hard
to work out what the jumpers do and how they need to be set up.
I'm looking forward to seeing what I can do with that tiny
feature-packed 4K micro- when I finally get time.

Regards
Bob

Hi all

For what it is worth, I just got my Z8 & took me a while to get it to
communicate with the PC. I accidently found it worked immediately after
switching on the board (D1 PA2 on steady). It did not communicate with the
PC while the demo program was running. It appears to work on both USB1 & 2
although I can't get it to work as yet on a USB2 PCMCIA card in an IBM
Thinkpad
I have J2,J4, J7 in. Others are in the DEMO position

If you look at the schematic you'll see the best settings for the
jumpers: I have j3 out and j6 out so the don't interfere with j4
and j7 respectively.

regards
Mark

Hi Guys, yes it was AUD $16 landed on my doorstep
and I can only get it to run on my NVidia chipset
mainboard by turning off USB 2.0 and running on
USB 1.1 . I've flashed the latest BIOS (which
originally had USB problems) and installed the
latest drivers but it's still dead on USB 2.0

I suspect a driver problem combined with some quirk
in the smartcable implementation as my USB 2.0
memory stick works ok at least.

Hi Mark

I did note that, but I found it still worked with them in. Still coming to
grips with it. Lot more involved than a picaxe08 (which I've also just
started to play with)

BTW noticed date sent 17/06/2005 @ 3:19PM. What time zone are you in??

actually it was 9:49 PM my time

Atmels certainly ain't the ducks guts either.

You can easily lock up their ISP port making the chip useless in any
serial programmer. Just what you need when you have a part soldered
onto the board - real nasty.
Their ATtiny26 device wasn't compatible with their own development
system either - needed modifications, and wasn't adequately documented.


I certainly had a very unpleasant introduction to Atmels.

Dave

The main problem I've had with the Atmels (Mega16 and Mega32) has been
the oscillators switching to external - which effectively makes them
dead as far as a serial programmer is concerned.

Simple solution - inject an oscillator into XTAL1 and change the
lockbits.
