N8 (4314) and PPIDE about romwbw

[b1ackmai1er]

Hi Andrii, looking at the n8-2511_-_ jumper settings file indicated to me that the PPI port should actually be $84 as $80 is printer, Keyboard and Mouse. Try that port address as PPI base.

Regards Phil.

Hi Andrii,

I tried it on my N8 which is a 2511 and it worked. The only change I made to the config file was to enable PPIDE:

PPIDEENABLE	.SET	TRUE

My boot up messages are shown below in case that helps.

This configuration is indeed not on my normal regression testing list because it is not common. Most people prefer to use the SD Card slot. With that said, the IDE port is fast and effective, so a very reasonable choice.

@b1ackmai1er The correct I/O port is $80. The 8255 at $80 is for either an IDE device or "parallel expansion" such as a DSKY. I know that parallel expansion is a confusing term. The 8255 at $84 is specifically designed for printer+keyboard+mouse.

Thanks,

Wayne

Hi Phil,
I've thought about it before. Pcb have 2 PPI. Left (U2 on sheet) and right (U7).
To U2 connect LPT Port (P38) - port A PPI (through 74LS07 - U1, U65E,F) and the younger half of port C (PC0-PC3) through 74LS06 - U8 and the eldest half port B (PB4-PB7), key and mouse (port B (pins 0-3) and eldest half port C (pins PC4-PC7).
So this port (left on board U2) is completely busy.
CS for U2 go from pin 14 U58 and om sheet have name /CS_PPI2.
To U7 connect to socket P31 (all 24 pin all prot of this PPI) also PA0-7, PB0-7 and PC0-2 and PC3-7( through 74LS14 - U63))
CS for U2 go from pin 15 U58 and om sheet have name /CS_PPI1.
What am I talking about? ))
I checked all the options and the table of truth.
I think there are no hardware problems.
The keyboard works on 84 port and when access to 80 port lights up the LED on the adapter. But then nothing happens.

[AndriiKu]

Hi Wayne,

Before I wrote, I tried all the options.
What can you advise me?

BR
Andrii

[AndriiKu]

I'll try prerelease 3.1.1

There is hope to:.

• WBW: Updated IDE and PPIDE drivers to improve old CF Card compatibility

They write it off

BR
Adrii

[wwarthen]

I'll try prerelease 3.1.1

It is worth a try, but I will be surprised if it helps. The compatibility issue was pretty minor and you have already tried multiple CF cards.

Can you reply with a copy of the system boot messages (similar to what I posted?). This will help me understand the exact scenario.

Thanks,

Wayne

Sorry, I missed that. However, I just get a 404 error when I click that link.

[wwarthen]

One more thing you can do to provide more information. Set the PPIDETRACE config variable to 3 in your config file.

PPIDETRACE	.SET	3

Try booting after implementing that setting and send the messages.

Thanks,

Wayne

Hi Andrii,

Thanks for the boot messages and trying the TRACELEVEL change. This does help me see what is going on.

First of all, the 8255 is being recognized by the CPU just fine.

Communication between the 8255 and the CF Card is marginal for some reason. I can see some data exchange between the CF Card and the 8255, but it fails with a timeout in different places in the two different boots. This is indicative of a poor connection between the 8255 and the CF Card.

I would suggest a thorough examination of the solder joints at the 8255 and the IDE connector.

If I understand correctly you have used the CF<->IDE adapter successfully in a different system, so that should be OK>

I suppose there is one other possibility. You are using a 4314 motherboard. This should be equivalent to my 2511, but I have never tested a 4314 and I don't know if anyone else has tried the PPIDE port of a 4314. I suppose it is possible that there is a routing issue on the 4314. However, that would typically result in a complete failure of the CF Card interface, whereas yours is "kind of" working.

I'm sorry I don't have any other suggestions.

Thanks,

Wayne

[AndriiKu]

Hi Wayne,

I compare part of sheet whis PPIDE on 2511 and 4314. And part where formed CS for PPI,
It's same.
Yes. It CF card and adapter work to Z180 Mark iV without any problem witj 3.0.1 BIOS. But there's no PPIDE.
Ok, I'll try check other CF card and may be ATA DISK MODULE from HP Thin PC, I use it to other project.

Thanks
Andrii

[wwarthen]

It occurred to me to ask how you are powering the CF<->IDE adapter. You are probably well aware of this, but it needs either a direct power connection or to be powered via pin 20 of the IDE interface (assuming the adapter supports power via pin 20). If you are powering it through IDE pin 20, you need to short a jumper. This is jumper K2 on the 2312. Not sure about the 4314, but I would guess it is the same one.

-Wayne

[AndriiKu]

I brainstormed. And rang all the tracks around the PPI and IDE connector.
I found output a PPI panel with cold solder. This is the pin of 12 - PC5.
My stupid mistake cost me many hours of tests. I'm sorry to bother you.
Now everything works perfectly.

Yeah, the old cold solder joint issue. That will do it every time.

Very glad you got it working! I will close this issue now.

I had an Ampro Little Board Z-80 that took me 25 years to get working, because of a defective IC socket.

[wwarthen]

I had an Ampro Little Board Z-80 that took me 25 years to get working, because of a defective IC socket.

OK, so that is a whole new definition for perseverance!

[wrljet]

LOL! Well, when I assembled the kit in 1983 or so, it didn't work, and I was unable to figure it out.

Years later during a burst of nostalgia I dragged it out and found the bad socket in an afternoon.
