DIY-A586 v1.6 von piotr_go

Well ok, at least I didnt release any magic smoke... yet
At this point I have all components on the board. However when I connect usb-c power I dont get LED-s up. I can mesure 5.125V next to USB connector.

I can tell some component are getting warm but no picture, no LED-s.
Any sugestrions to where do I start debugging? I am including picture of the board if there is something obious.

Cheers,

Ranko

Yep. I did try that first but still the same. No diiferance . Shuld I get LEDs up without conecting pins 7 and 8 of W25Q128JV?
I am noticing 1117M3 is getting hot quickly. Do I have right component here?

Cheers

No.

Maybe you switched them? 1.2V close to FPGA. Check voltages.
Check 16MHz generator.

Oh crap! I am noticing now two different components, two different voltages. To start with I probably ordered wrong specs
Any chace you can recomend something from Mouser/DigiKey for these two components?
I am refering to SPX1117-1.2v and 3.3v. I am very lame with voltage regulators

Cheers

Ranko

What regulators did you use?

3.3V:
https://www.digikey.com/en/products/detail/maxlinear-inc/SPX1117M3-L-3-3-TR/2472291
1.2V:
https://www.digikey.com/en/products/detail/texas-instruments/TLV1117LV12DCYR/2666506

Check first with bench supply or something, your fpga might be dead if you connected 3.3V instead 1.2V.

I used compleatly wrong link: https://www.mouser.com/ProductDetail/maxlinea...S%2FCBhQS5rCrAuP2Q%252bV2BLw==&countrycode=CA¤cycode=CAD

Output Type: Adjustable.

Stupid.

Ok! I ordered new components. Knowing DigiKey I will have this until tomorrow evening.
Piotr thank you for your amazing help and quick reply!

With some luck we will have sucsesfull boot shortly.

Hmmmm, if i'm not mistaken they should output 1.25V, that's good news.
Which one heats up? 3.3V rail or 1.2V rail?
Can you messure voltages?

3.3V rail get hot very quickly!
I guess not surptisingly

Ranko

Desolder the 3.3V 1117 and check (pcb) if 3.3V is shorted to gnd.
Measure 1.2V.

Sorry Piotr, I received your message somewhat late. I already removed v regulators. However I can notice that I have continuity on the board for 3.3v-reg position pin1 to pin4 (included on the picture). I am not sure if this is normal?

Should I put regulator back on 1.2V position? Where do you want me to mesure exactly?

rrodic hat geschrieben:

I am not sure if this is normal?

No.
Desolder 16MHz generator (i'm guessing) and check again.

Yep. You are right it is the crystral.
This is the one I have: https://www.digikey.ca/en/products/detail/AM1...0RXMG45TGtcL1dRUWJ2RE5cL0JMY2o0blZuY2hSIn0%3D

Looks like I was mounting the component the wrong way. I was trying to do it the same way as in your picture but perhaps orientation for this one is different?

I checked continuity of the crystal and looks like it will create a short every time if mouted vericaly?

It's because it should be 16MHz 3.3V generator, not crystal.

That explains it

Alright! Order submitted. By tomorrow, latest day after tomorrow I will have components.
Once I have working board I will spend some time making online component locator and perhaps detailed BOM for lame people like me. I asume your list Piotr is more than pricese for people with experience and knowlage. In my case at least PDF with component spec. would be of use. Perhaps I can do that as well, download documentation for every component as referance....

Piotr, again thank you for amazing suppot. I really enjoy this journey!

In the meantime I want to show you what I did receantly
I had few minor issues during the build but in general smooth ride..

Nice work.
It must have cost a fortune.



8088 is Micro 8088, zx-uno pcb is modified by me.
Rest are my retro projects.

Omg! This is freaking fantastic!!
I love it all!

Re-Amiga 1200 was ok in terms of the price. Donor board was dead. I only replaced Paula chip. But I spent a fortune on my new hobby buying all sorts of stuff

What is Cyclone IV system?
If I am not mistaken Vampire runs Cyclone III. So this is probably powerful little board?
8088 is also very cool. New old PC

Your work in remarkable!

And i forgot this tiny thing (unfinished):

This is all fantastic stuff.
I need to chek all this.

Up and running!!!



Question. So far everything works great!

1. I still dont have PS/2 mouse so I noticed that my original Amiga mouse is not supported - serial port 1. Is this expected?
2. I created KICK31SD.ROM using patch.sh - Amiga600 3.1 Rom. When used in DIY this ROM31SD.ROM works well however I dont know how to boot Amiga HDD from SD? I have SD card ready (2GB with WB 3.1) very basic install - works on Amiga 600. Following the instractions from youtube video: Load AmigaCore with KICK31SD.ROM, insert SD card with AmigaOS, reset and OS will boot? In my case I gey only kickstart screen. Am I missing something?

Cheers,

Ranko

1. In standard core only PS/2 KB & mouse. I will send you A500 KB&M version.

2. SD image:
https://www.elektroda.pl/rtvforum/viewtopic.php?p=18128871#18128871
You can format ClassicWB partition and install Workbench from a floppy.

Check md5sum of patched "KICK31SD.ROM": 75c85b4119f913c64344e8022363d1b7

Thank you for your quick reply Piotr.
Yes, md5 is correct.

My question is what do I do with this RAW file? I asume I just need to DD this RAW dump to SD?
Since I did that and I was not able to boot Workbench. Now from what you are saying this is just partition reconizable by DIY-A586 so after dumping RAW to SD I will need to use WB floppy to setup the system? Is there any way we can DD already existing pre-installed Amiga HardDisk image?
Also is there any limit in terms of partition size. SInce this is 3.1 I asume 4GB is the limit?

Cheeres,

Ranko

Yes

What exactly happened?
Can you make a video (with led's visible)? Start from power on.

rrodic hat geschrieben:

2 amiga partitions present in SD image.


================ update ================
Amiga only SD image with 2 empty partitions.
Updated Kickstart 3.1 patch.

I am still unsecsesfull regarding SD+3.1
Here are the steps:

First I am using new 2GB SD card.
dd if=SD_clean.raw of=/dev/disk3 bs=2048k
....write is sucssesful.

Then I located original rom 3.1 from Amiga 600. I will copy the ROM from AmigaForever dir to patch dir, rename to KICK31.ROM

Execure patch.sh script. Since I have xdelta installed everything worked fine without any warnings about MD5 since I have the right ROM. I also manualy checked MD5 and it is a match.

At this time I asume I have the right KICK31SD.ROM. I will copy the file to my other SD card that I am using for programming DIY. Also I will copy latest Main, Amiga cores provided by Piotr.

Next step I am updating cores on DIY and uploading KICK31SD.ROM in FLASH section. I asume this is the right place.

I will execure Amiga31+SD core and everything works well, I have kickstart screen. I will insert Wokbench 3.1 install floppy disk. Disk will boot sucsesfully.

I will insert my 2GB SD card that I prepared using DD and press reset button.
DIY will boot Amiga using install floppy again.
Then I will start HDD Partition software - ->No disk found<- (See the image)

SDHC(>4GB) only.
I didn't bother with the older ones as they can't be purchased anymore.
(yeah, i know about ebay)

Same result
This time I was using WinUAE to check SD card and make sure I can see Amiga partition. Everything looks good but DIY is not detecting SD card within Amiga OS. Reason still unknown.

I am including the image of SD card and result in WinUEA.

I write image with command:

Zitat:

cp SD_clean.raw /dev/sdX

without number at the end.
(Be careful)

Are you sure your card is "/dev/disk3"?

What "dmesg" shows when you insert your card.

I will try method you suggested now.
Yes I am sure, reason is I was using OSX in this case. You are probably using Debian based distro.
Keep in mind, WinUAE and real Amiga can read the card and can detect two partitions you made.

I will try cp method now just in case. You never know.

Cheers,

Ranko

If the card works for uploadning cores, it should work with amiga.
There must be something wrong with writing the image.
Partitions should be visible in workbench.

I will try with my Ubunty notebook.
Maybe OSX is doing something strange.

Wait, what do you mean used for uploading cores? This is only two Amiga partition(s) image no?
I didnt check if there is any FAT32 partitions. I will do so now.
