Individision AVA MK3 4000D/CD32 no signal at all

I believe always chipset must be CBM but look at my to REV of motherboard 1D4 and B1:

1D4 has Hewlett Packard Chip::

1B:

I thought the Hewlett Packard chip was a SCSI controller? It is on the 4000T anyway.

The HP chip in the upper picture is Lisa, and it's the most reliable Lisa chip of the three possible vendors.

Cold boot has been a solved problem for quite some time. Logo display duration can be set to 0 - and that was since the product was introduced.

Hi Jens, just in case it is useful information: I recently bought the Indivision AGA Mk3 for my A1200 and I'm also facing the cold boot issue.

The A1200 is fully recapped and apart from the Indivision it is equipped with an ACA1211 and a CF-card adapter on the IDE port, replacing the HD by a CF card. I'm using an after-market PSU (Link to known-bad Keelog thing removed).

After adding your 'indimk3reset' tool into the startup-sequence, upon cold-boot I'm now getting an output on screen, so the issue is fixed - although it's a bit unfortunate as this is only a workaround and not a real fix on hardware level.

Reading some of the threads in the forum on this topic, it seems as if the issue is likely related to the 5V rail being less clean/less stable than expected by the Indivision. Do you have plans for a new revision of the Indivision hardware rendering it less sensitive / more tolerant reg. the 5V rail ?

a real fix on hardware level.

Try a known-good power supply. Keelog uses the same chassis as many other known-bad PSU replacements. Please read our PSU FAQ to find out about the three key specifications that Commodore has put out, which are all violated by these PSUs.

I have recently purchased the MK3 and installed it into 4000T

I have had to use the reset utility.

Please let me know the Warranty ID and the purchase date, along with the reseller you bought this from (if not directly from us). We've been shipping the last Indivision AGA MK3 boards with new CPLD code that was developed on a machine that a customer was kind enough to send to us - I was finally able to reproduce the effect here and develop a fix. I'm assuming that you have a version that was still shipped with the old CPLD code, but I'd like to verify that.

Have a 750w snow silent PSU, I’ve also tried and Corsair SFF 450w PSU and no matter what, cold boot will not initialise MK3. It’s fine for the most part

I doubt that any of these are "fine". Please read our PSU FAQ about technical details why ATX power supplies are not a good idea for Amigas.

I have a BFG which can accommodate additional boot rom data for loading libraries or such.

Maybe something can be put here to initialise the MK3

It's just a few register writes, and the "MK3reset" tool is really small, so yes, your thinking is correct. However, somebody else will have to do that, as I'm not supporting hardware that other companies have made.

My warranty code is FTGX as printed on the sticker and box.

There must be a 5th digit. Note that the code is case-sensitive and may include other symbols such as $%&/ or similar.

Quote from Mvickers03

the board is from Alinea computers and was purchased around 6 months ago.

The CPLD fix didn't exist then, so yo definitely have the original version.

Quote from Mvickers03

Is flashing the CPLD something I can do at home? I have done this before with various CPU cards.

The Jedec file isn't public. However, we have the JTAG updater, originally made for the ACA500plus, but it can also be used on other products to update the CPLD. Where on the planet are you? Note that we can't ship to the US any more, so if you're in Trump-land, you're out of luck.

I will be purchasing an MK4 also when they land for my other Amigas.

Didn't comment on that, but I believe I should: There will be no MK4. The MK3 design has been successful for a very long time already, and I haven't found anything that I should improve on it (apart from the startup problems that a few customers reported, which are solved now). Customers seem to agree, as I'm getting daily questions about availability of the A1200 version.

So the decision to build the MK3 design without any changes came naturally - I just don't know what to improve.

Jens

Quote from mvickers03

I did read that MK4 was imminent?

A new production run is ongoing, but it's still the MK3 design.

Quote from mvickers03

I think I just need the .jed files and pin numbers / names?

Again, the jedec file is not public, and you'd probably have a hard time setting up the JTAG chain, as the FPGA is in there as well.

Quote from mvickers03

I am from UK

Still a customs border, but not as problematic as USA, so when I finally get around to publishing the JTAG updater, we'll have a small board that I can ship to you. Note that these are built to transfer the intellectual property only. The hardware itself should be returned within 12 months either to us, or to a reseller near you, so we can re-use it for other customers.
