DIY-A586 v1.6 by piotr_go

Hello everyone.
I am preparing for the build. However I have few questions. First do you have any component locator available - online or offline?

Second, once I am done with a build, do I need any special (Xilinx) programming tools/software for JTAG -for uploading low level firmware? Perhaps this main .bin file? If not how is this done? I assume emulation cores and kickstart can be loaded from FAT flash?

Since I will use this board only as Amiga system, can I load Amiga emulator and rom without entering main menu?

Sorry for my ignorance. This is my first FPGA build.

Cheers,

Ranko

That is fantastic. Thank you for your reply!
I asume "main (v0.4 beta6.1).bin" file will go to 25q128? Yes?
I think coincidentally I already have progammer foir this chip!

Thank you for amazing Amiga board!

Regards

Ranko

Looking at the bottom.png and top.png for component location, I assume 100 means 100 ohms? 4k7 is 4.7 kOhms? etc... Only capacitors have units included? If no units included - it is resistor? Right?

Cheers

Ranko

That is fantastic! Thank you for the pictures. That helps a lot!
Also during the project I will make web-based component locator.
I will share files with you when done so you can host it somewhere if you like the idea....

Cheers,

Ranko

I think I have BOM ready. Also I will order the board shortly.
However I have one question. Looking at the BOM file provided with a project I am not sure what these items are:

R6 R_0603 0603
R7 R_0603 0603
R9 R_0603 0603
R11 R_0603 0603
R13 R_0603 0603
R14 R_0603 0603
R19 R_0603 0603
R20 R_0603 0603
R21 R_0603 0603
R22 R_0603 0603
R23 R_0603 0603
R24 R_0603 0603
R25 R_0603 0603
R28 R_0603 0603
U$1 ESD ESD ESD2
U$2 ESD ESD ESD2
U$5 LOGO-DIY-A586 LOGO-DIY-A586 LOGO-DIY-A586

I asume this is comming from CAD software but I am not sure if any of these are of interest?
Also on the picture I can see two very small IC-s located just next to the HDMI. I dont think I was able to locate these components in the opriginal BOM. Any sugestions?

Cheers,

Ranko

For fuse is this good enough?: https://www.digikey.ca/en/products/detail/bel-fuse-inc/0ZCJ0050AF2E/4156300
I also asume this ferriteB will do? : https://www.digikey.ca/en/products/detail/murata-electronics/BLM03AX800SN1D/2485952

And with that we are done!
I already submited order for boards. 5 gold boards will come shortly.
I will keep you posted about the progress here, send some cool images etc...

Ranko

Thank you sir! I am all set now. Tonight when I get some spare time I will submit order. I just finished ReAmiga 1200 project and I am so looking forward asembling your fantastic board! As I mentioned I will document my progress here and finish web-based locator - like this one: https://amiga.embeddedsoft.ca/ I think it may help in the future. I will also include documentation for the components so people have starting point regards size, specs etc... Alought your docs - provided with the files are very good and for many people more than enough.

Cheers

Ranko

I am on my way with build!
Question. Do you guys know what is this?
Looks like ferrite bead but I am not sure?

Acrtualy nevermind. I figured out this is FB as stated in previous post.
However I have question regadring that 10Kohm 4-array for JOY1 and JOY2.
Do you have any specs for this part? I am having trouble finding someting on DigiKey and Mouser... They have so many similair parts.

Cheers

Ranko

Fantastic!
Thank you.

Here is the progres...

Just waiting for few parts. I ordered some components in wrong size. Hopefully day or two. Also I programmed flash sucsesfully! Chip is on the board. I love this little computer!

Here is work in progress:



Ranko

Thank you for the heads up! I think I will cut plastic on the other side. I kinda like black colour of the plastic. makes the board look sexy!

Heh Very much true!

I am still waiting for DigiKey to deliver packet.
Looks like tomorow by 2pm is ETA! I can not wait to power on this puppy as Dave would say
