cfidecp293 installation help!

[save2600]

It's Saturday night and I've been messing around with 2 Amigas all_day_ long to no avail. I'd really like to put these things together and move on with the evening.

Installed the cfidecp293 in my A500 rev. 5 mobo. Kickstart 3.1. Wired up the /OVR and /INT2 lines at the expansion port. System boots into floppy and I get the insert Kickstart screen. System obviously works. What doesn't work and is not recognized is the HD controller on this card. Shouldn't matter what the device is, but what the heck is it anyway? scsi.device just like the A600 device (even though it's IDE).

Can anyone help troubleshoot? I've got 2 CF cards that work fine in my slingshot and A2091. I also hooked the CF<>IDE Adapter into the port that hooks via ribbon cable. Same thing: nothing. HD capability is dead or nonexistent.

Yes it is scsi.device like the 600.  I'm not sure why it doesn't work on yours and both of mine are early prototype version 1 so I'm not sure how to help further. You are booting off of the WB Installation floppy correct? If you are using a CF adapter on the end of the ribbon cable make sure to supply power to it (IE: from a floppy connector). My system wouldn't supply power for the CF card through the data cable like some PC controllers will.

Yes, it's scsi.device but it doesn't show up in the list. You need to click Define New... and on the next window select Read Configuration. I got my cfide v293 with 4gb cf working that way.

Well, scsi.device doesn't show up at all, so I can't proceed with defining anything new, I can only quit. Unless you mean I need to insert the 3.1 Install disk and "install" it that way. But I already have a known good, formatted CF card with OS3.1 already on it. Shouldn't the card just "work" upon insertion of the device? What would the Install program place on the CF card that isn't already there in order for it to be recognized by this home made device? And if that's the case, seems to me the thing would never autoboot if it needs something extra to get it going. When you first turn on the computer, you can tell the device isn't even bothering to search for a boot record as the Kickstart screen immediately pops up.  

And yes Jeff - I supplied power to the end of the ribbon cable AND also had a CF card inserted at the end of the unit - but not at the same time of course. Using the SCSI search tool from ASIMCDFS, it seems as if nothing is there. The scsi.device part of this board appears dead.

The pin nearest to the CF connector is /ovr, the next one /int2. It should be ok to leave /int6 unconnected, this signal leads to the clockport connector and is not used for IDE.

Is the CF master jumper connected? Is KS3.1 rom version V40.063?

If you connect an activity led, it should blink after Amiga is powered on, before the boot process continues (It checks for a bootable IDE/CF disk.)

[mrmkl]

Is there any other expansion connected? RAM expansions that use D8xxxx-DExxxx would conflict with cfidecp board.

[save2600]

With LED connected in both positions (IDE and CF card), I get NO flashes or light.

Master setting is jumpered and KS is indeed 40.063.

Only ram is A501 and system is configured as 1mb Chip.

So it seems it's dead or no power getting to the IDE section? Should I try supplying it with +5v somewhere? If so, where?

[mrmkl]

EDIT:

Are the connections to the /ovr and /int2 pins good? The pins on the header are a little short. Wire to pin header connectors often expect a little bit longer pins. (such as the A500 keyboard pin header and the wire-connector)

For your last post seems you really have a hardware problem.

 Check if the voltage regulator grab the +5V from the computer and is supplying +3.3V.

 You can safely sack the CPU from the board before powering the Amiga for this purpose.

I don't see there is need to add any +5v supply.

Yes, both /over & /int2 pins are soldered directly from the header pins of your board to the locations at the expansion bus. Thinking there might be a break somewhere along the way, using my DMM, I checked continuity from the expansion bus to their respective places on Gary & the CIA and they are fine.

You're saying the regulator is underneath the CPU? Okay, I'll check that and see if there is 3.3v...

-edit-

Underneath the CPU is Q1 & Q2 - those are the only two transistors I see. Both read +4.8 or thereabouts. The transistor sitting outside the socket (is that not the regulator?) gives me the same reading. I do not measure 3.3v across any of the transistors...

Also, device LD33 (the regulator?) is super hot to the touch! You cannot hold your finger on it, not even for a second. I measure +4.8 volts across its 3rd from the left leg (emitter?). Not 3.3v

BTW: the two black components to the right of the LD33 regulator... the one directly to the right of it, does not measure +4.8 whilst the other one does...

[mrmkl]

I think I might discovered the problem, the new type of CF-connector I used with some boards has pin order somehow different ... And I might have tested the board using the IDE connector instead of the CF slot. (More at the end of this post...)

The "LD33" regulator shouldn't get hot.

Do the CF cards still work with the slingshot+a2091+scsiidecf combination, or are they burned? I hope not.

What kind of IDE-CF adapter do you have at the end of the ribbon cable? Unlike I wrote in previous post, +5v should be supplied separately, because no +5v supply is fed through the 40-pin ribbon cable.

The unsuitable CF-connector I've soldered on some latest boards have pins in swapped order in pairs, such that signals that should go to top row of pins go to the lower row, and vice-versa.

[mrmkl]

Can you post a picture of the CF-connector end of the board, to identify if it is the wrong type?

CF cards still work in my slinged A2091 ... whew!

And yes, I supplied power to the CF<>IDE adapter at the end of the ribbon cable. Nothing.

And yes, I supplied power to the CF<>IDE adapter at the end of the ribbon cable. Nothing. Same as when a card is inserted in the built in CF slot. No LED activity at all upon startup, reset or anything. This thing seems shot to me MRMKL and I'm no stranger when it comes to soldering. I didn't do anything to have caused this thing to fry. Perhaps I could use this still though in my A1000 as a riser so another cfidecp293 could fit in harmony with the disk drive? lol
