Minimig Discussion Forum

In my opinion, joystick is much better in cursor keys + CTRL

And no, I don't mind about the filters either, That space is better used to another features or improvements.
thanks for your work, chaos: The DE1 is becoming a SERIOUS minimig contender by now...

It is really fun to hack on the minimig port - sort of relaxing Although I currently have a ton of other work, I always come back to the minimig code to update this or that. And it also brings back some Amiga architecture knowledge lost in almost 15 years since I've done any Amiga programming

But, I digress ...

It's good that at least two persons agree with me about the filters and joystick emulation
I'll try to move the joystick emulation back to cursor keys and at the same time disable the keyboard buttons - I think it is OK if the joystick emulation can be switched on/off with the NumLock key.

Does anyone else have any problems with the SD card in the new build? MMrobinsonb5 reported that some SD cards that used to work before don't anymore. Anyone else with any problems?

Anyway, after cleaning the code a little bit and some work on the firmware and build process, the current version will be ready for a proper release. I'm almost done with the flash bootloader, which will then load the control firmware from SD card, so it won't be necessary to reprogram the flash chip each time a new firmware is released.

For the future, the plan is to upgrade the SDRAM controller and cache, which could bring the TG68K speed in the 68040 range. And then, *maybe* it will be possible to put some AGA code in the design, but I still have to study this.

Enjoy!

A new test release (hopefully the last before a fully tested &working version) of minimig-de1 is available here.

Things changed are:
* fixed fastRAM bugs with help from MMrobinsonb5
* re-enabled SD card partition support & hopefully better SD card compatibility
* small changes to sound and video output, optional sound mixing added (L-R channels are moved closer to center), volume control (doesn't work yet!)
* other smaller changes & cleanup

Please test it and report any problems you might come across!

Enjoy!

@Chaos...

I have tried all of your test releases and can't get any of them to work...
fiddling with flash address and sw5...

always get some arm failure...

I have two different DE1 boards...will try the other one today...

Can you put the kick in flash too...would it get us more fast or slow ram?

The only thing that I can get running with hardfile support is the original
DE1 port from like 2011/12/30....

sjamaan:

I'm sorry, I forgot I changed the switch mappings. Here is the current map (SW9 is on the far left):
- SW9 : 15kHz switch
- SW8 : joystick emulation enable (currently not tested)
- SW7 : audio L-R switch
- SW6 : audio L-R (centered) mix
- SW5 : flash boot location (0/2MB)
- SW0 : PLL reset (will be removed)
- SW4-SW1 are connected to control CPU, but currently unused

edit: are you saying that none of the test releases work? Did you program the .bin file into the flash using the DE1 control panel (remember, you have to first erase the whole flash and then program the .bin file)? Can you please see which red LEDs are lighted once you turn on the board?

Enjoy!

LED08 is lit...

I first turn off the DE1.
Set to RUN.
upload the DE1 contol panel .sof
run the DE1 control panel.
open the usb port.
erase the flash.
click/check the file length option....and then write a file to flash the de1_boot.bin

then I go back to the programmer and upload the minimig_de1.sof

I get this (LEDR8 is lit and LEDR7 flashes a sec and...)

It is strange...I got the Zet processor running...no probs with flashing and everything...
maybe I am just forgetting something....

btw what address do you put for the 4MB offset...4096 in hex?

and the software version of the de1 control panel is 1.0

If it's getting that far, everything's working as it should, it just doesn't like your SD card. Because of the changes to the OSD processor and how the bootstrap is handled, there are still SD card issues to iron out.

On the plus side, it supports SDHC now.

OK, I just thought of that when I was standing outside...
I have been using an old 256MB sd card and I though about
formatting a 2GB that I have and trying that....

No deal...it is formatted FAT
I will try FAT32
