Hi people.

I bought a Terasic DE-1 last week from Mouser. Although I do want to play around with FPGAs in general as I have a Spartan 3E based project on the go, the main reason for the DE-1 in particular was Minimig. I'm pretty sure the board is OK as the internal test stuff works fine and I've loaded up a few other projects, but try as I might I can only get an early version of Minimig to work reliably. A build of 1.4 (I think) from TSL.

I've tried and tried over the weekend to get either release 5 or 6 to build and work reliably. The reason I say reliably is because after enough messing about I can usually eventually get it to boot, but it can take half an hour! And if you power it off and back on you're back to square one (I don't mean I've programmed the SOF rather then the POF!). It does seem like the odds of it working gets slightly better as the board warms up.

So, My DE-1 has ISSI SRAM and SDRAM with 90ns Flash from Spansion.

On release 5 I sometimes get a completely blue screen. Sometimes the Minimig logo in top left with nothing else. Sometimes the intro text is OK, others it's all over the place. On RS232 sometimes it detects my SD Card as FAT16, sometimes as FAT32, a lot of the time I get Error 2 or 6. It always says my SD Card is detected as SDHC when I don't think it is (it's 512MB). I have also tried a 128MB card, and an 8GB (which clearly IS SDHC).

All in all I don't get very far, but once in a blue moon it will boot to KS3.1 and I can insert a WB disk and get to the WB (though I've not wired up a mouse yet so that's as far as I can go! I did manage to play a couple of games via the keyboard at one point :)

Finally, on release 6 over RS232 I always, always get to the point is says KICK.ROM not found when it's there quite happily.

SO... aside from any help anyone can offer, a general question, is it normally the done thing to build the FPGA code in Quartus, or am I OK to just load the SOF / POF? So far I'm just doing the latter.

Through looking in various places online I've managed to gather that switches:

9 - Scan Doubler (on as I'm using VGA)
8 - ?
7 - ?
6 - ?
5 - UART 68k or FPGA doesn't seem to make any difference
4 - ?
3 - Turbo mode? Tried on or off, makes little difference
2 - Reset of some internal system
1 - Reset of some internal system
0 - Reset of some internal system

None of that makes much difference to me.

Hi MartinW,

you are the second person with DE1 problems in a short time. I'm not really sure what the problem is, as it seems the builds work for (most?) of the others, well for me anyway.

My best guess is something is changed on your revision of the DE1 board, either the layout, which would affect the timings, or the SRAM or SDRAM chips are not of the same spec, possibly a different FPGA chips is used which is for some reason not compatible with mine. I do remember that the first Cyclone II's had a problem with the dual port memories inside, which made them incompatible with the later revisions, but I guess that was fixed a long time ago. Could be some new bug, though.

I would like to ask you to do a few checks that might help me debug this problem.

First, get the release 5 from here: http://www.krajnc.org/files/minimig-de1 ... 2-rel5.zip . Try to both program the FPGA directly (sof file) and the serial config chip (pof file). Make sure you put the de1_boot.bin file from the zipfile on the root of your sdcard. Also use a known working kick.rom file, you might want to test it in WinUAE.

Second, put all switches on the DE1 in the up position (away from the edge), except switches SW1, SW2 & SW3 (the second, third and fourth from the right to the left) - put them in the down position.

Boot the minimig core and please report what you see on the seven-segment display, which LEDs are turned on or blinking, and paste the output from the serial console, if possible.

Please also copy the markings from the FPGA (Altera), the SRAM (ISSI?) and the SDRAM (ISSI?) chips, and post them here.

Hopefully that will shed some light on this strange behavior.

Just for your reference, here are the functions of the switches on the DE1:
SW9 - scan doubler
SW8 - no function (enabled keyboard joystick emulation in previous releases)
SW7 - audio left/right switch
SW6 - mix left/right audio
SW5 - UART select Amiga / control CPU (not in previous releases)
SW4 - no function
SW3 - cache control (I don't think this was enabled for release 5)
SW2 - cache control (I don't think this was enabled for release 5)
SW1 - cache control (I don't think this was enabled for release 5)
SW0 - PLL reset (a complete reset of the system)

No problem, I should be able to do all that and report back later on. Is that the right link though? The file name says DE-2.

[EDIT] PS: Thank you so much for the switch settings listing. I was expecting to see a 'UCF' file with a net list that would allow me to tie them up to what their functions were but it's fairly obvious I have a bit of learning to get yet to apply what little I know from the Xilinx world to Quartus :)

Sorry, I was a little fast ;)

Here is the correct link:
http://www.krajnc.org/files/minimig-de1 ... 1-rel5.zip

If you would like to look at the source, you can here:
https://github.com/rkrajnc/minimig-de1/ ... _de1_top.v

At the top of the page, there is a button "branch: master", you can click it, select the "Tags" tab and you can see the same file from previous releases, if it helps.

OK, thanks. I know I won't get any further because that is the file I've been using, but I'll certainly provide all the debug info and help that I can :)

Right, first of all, freshly formatted SD as pic below. File 'KICK.ROM' verified to work in UAE. Also copied the de1_boot.bin file. At the moment these are the only two files on the card. The card is my 512MB card. kingston branded. Nothing about SDHC, simple SD/512 written on it.

Image

OK, so I've just programmed the config flash (pof) which incidentally is coming up in Quartus as EPCS4.

So far, I have blue screen with miniMig logo in top left as it should be, nothing else on screen. DE-1 display is reading "F 00", LED is lit solid.

Serial output is as follows:

Code:
**** MINIMIG-DE1 ****

Minimig by Dennis van Weeren
Updates by Jakub Bednarski, Tobias Gubener, Sascha Boing, A.M. Robinson & others
DE1 port by Rok Krajnc (rok.krajnc@gmail.com)

Build no. 168
git commit 4525614aa9cff623fc797fa7088e554cf52731a9
git tagminimig-de1-rel5

For updates & code see https://github.com/rkrajnc/minimig-de1

If I push SW0 down and back up, the press KEY0 (a soft reset?) the LED9 goes out but otherwise no change. No new info on serial or screen.

I will now program the FPGA directly and report if there's any difference...

OK, that makes little if any difference. Nothing new to report on the Serial display (as in, really nothing new, not even the same thing repeated. I now have a plain blue screen (no logo), the DE-1 display still reads "F 00" and LED9 remains off. If I had to guess I would say Quartus did nothing more than verify the code was the same the program file and therefore did nothing. Quartus is showing my FPGA as "EP2C20F484".

Only other thing of note is that when SW0 is in the down position the LED display read "F 88" but I guess that's to be expected?

Just had to take a photo of these and zoom in to read them they're so small [:D]:

SDRAM 8MB
ISSI
IS42S16400J-6TL
BGN650000DJ 1217

SRAM 512KB
ISSI
IS61WV25616EDBLL-10TLI
E4A898K4X3 1230

FLASH 4MB
Spansion
S29GL032N90TF104
303BB744 B

FGPA
Altera Cyclone II
EP2C20F484C7N
K CBD9Y1249A
Korea
VBD9Y58984
3S1KA2Y0I
E1

Think that's it !

Please do let me know if I've missed anything. I dare say if I were to keep randomly flicking switches and pressing buttons then eventually it would come up. So I guess it's a timing issue...

[EDIT] Oh, something else that may be of note, I'm running solely powered by the USB bus since the power adapter it came with has a US plug on it and I haven't got around to trying to find a US to UK travel adapter. I'm in a small sea-side resort so whilst you'd think they might have such things for the tourists, I bet they don't!

OK, (unfortunately) it is not a basic problem.

Here is a link to the debug build of the firmware, use the .pof or .sof file to program the FPGA and put the other two files on the root of you SD card, and then paste here the output from the serial console.

http://www.krajnc.org/files/minimig-de1 ... esting.zip

Please also describe which green and red LEDs are turned on or blinking.

This will at least tell us where minimig is stuck, I'll see if there is anything I can do after that. On a quick glance, the SDRAM and SRAM chips should work, but it could still be a timing issue, since at least the SRAM is running at full speed, and also the FPGA is very very full (93%).

Oh, and this:
The SW0 is a control block reset. You don't generally need any other power source than the USB, any normal USB port should provide enough power.

I'm occasionally getting an extra two lines:

Code:
cluster_mask: FFFFFFE0
Drive found ...


Which is slightly odd as when trying the v6b2 version over the weekend I would get to the point of it complaining that "KICK.ROM" was not found, even though it's there.

Is it possible there is something speed related going on with the SD card? Last night I loaded up the control panel software and I had to click a couple of times to get it to read the info from the SD Card.

In fact, here we are. I just loaded the control panel software up again. I tried to read the SD Card and it said not found. Twice. So I removed the card and re-inserted it and then it read it. I then went back to Minimig. I initially got the same results as before, but after a couple of resets, got this (and sorry, it's quite long!):
