I put kickstart 1.3 on, the Amiga 500 catch appears. It doesn't read adf files, I understand that only the kickstart 3.1 SD allows it? However, trying to fire up some adf results in a constant reset.
Do you need to throw something into flash except a kickstart and an adf file?

Floppy disks only from station or station emulator.
There is no built-in flop emulation.

Does the amiga batch support AGA or only ECS?

ECS. Too little fpga for AGA.

It is a pity, because it would be a very nice competition for MIST.

What are the markings of US1, US2 ESD because I can't find it?

PUSB3FR4 or similar.

I forgot to mention:
QuadEnable must be enabled when programming Flash.
If someone does not do it, shorten pins 7 and 8 of Flash at the first start.

Good morning, but you can buy it because it still needs to be sold.

Unfortunately, I am not selling. You have to assemble yourself.

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

You need flash (25q128) programmer for first programming.

Not possible right now, maybe in the future.

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

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

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,

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

Rxx R_0603 0603 - not needed

LOGO-DIY-A586 - it's just logo on the PCB, you can remove from BOM

ESD ESD ESD2 - PUSB3FR4Z (ESD protection)

F1 - polymer fuse 0.5A
F2 - ferrite bead (under sd card)

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...

Wrong size.
I don't know why, but we use Imperial, not Metric for electronic components (not all). ...and pipes.

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

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

Dodano po 4 [godziny] 36 [minuty]:

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

Reminder:
For first boot You may need to short pin 7 and 8 of flash.

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:

I noticed a minor error.
Black floppy connector is reversed. The cutout should be at the bottom.
I don't think there are angle connectors with a cutout at the bottom. I used regular goldpins.

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!

Or you can cut the plastic key on the cable plug, which will be easier.

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
