I only have a question, I'll download an older Raspbian version, ok, but then should I do an apt update - apt upgrade or should not?

Start by not doing apt update/upgrade, and see if that works first.

alestanga · 15 September 2020, 21:47

so, I've installed 2019-09-26-raspbian-buster.img and then I've followed crowstudio's amazing guide.
booted the RPi inside the amiga and boom, PI0: and pi command were both working!
thank you very much, you've made my day!
now I can call myself an A314 user!!

Yay, welcome to being an A314 user!

Well done!

This also reveals some quite important information: it seems that something has changed in the latest versions of Raspbian (the versions after they renamed it to Raspberry Pi OS, from what I can tell) such that the communication with A314 is not working properly any longer. This needs to be investigated. I added an issue in GitHub: https://github.com/niklasekstrom/a314/issues/49.

And I second that 'Yay'!
So happy to see that you pulled through, despite all the challenges. Very well done indeed, and welcome to the club

CrowStudio · 16 September 2020, 08:09

Hurray ,and welcome! :-)

I couldn't have done it without your help!
I'm so happy that now it works but also the ride toward the goal has been fun, and also a learning experience.

for what it matters, before formatting my SD I had a version of raspbian from may I think (april at most), when I had the two 1488 and 1489 replaced on my amiga. that RPi was my modem emulator for the Amiga.
and that was the version that froze PI command on my system.

nikosidis · 16 September 2020, 09:44

Could the RPi be used to render GFX in Lightwave or as engine in emulators like MAME?

alestanga · 16 September 2020, 10:20

do you have a guide or something to make the most out of the PI disk in terms of speed?
I mean, to let the boot disk load the filesystem and then boot from the "hard disk"?
I've copied a few programs from the WB 1.3 disk to the HD, clock for example loads very fast from the PI disk, while CLI is slow and albeit being on the PI disk still access the floppy (I think it needs libraries, fonts and other stuff that is on the floppy)
how do I tell the amiga to just load the filesystem from the floppy and the rest from the PI disk?
for what it matters I have 2 goteks drive, one inside the A500 and one in an external case.
as I mentioned, I'm a noob

Eriond · 16 September 2020, 10:30

I just copied my complete WB installation to the PI0:, and altered the boot floppy's startup-sequence to just contain a bunch of ASSIGNs (like ASSIGN C: PI0:C etc.) ending in a ASSIGN SYS: PI0:, effectively moving the logical OS starting point to the PI0:
The last command on the boot disk executes the user-startup which is located on the PI0:S and from there on the floppy isn't accessed any more.
Here's a reference to the ASSIGN command, with some examples at the end: http://www.jaruzel.com/amiga/amiga-o...lp/assign.html
You will further improve the loading speed by setting the C assign first, because then all subsequent commands will be executed from the faster PiDisk. Making the ASSIGN resident is of course also a good idea.

CrowStudio · 16 September 2020, 10:35

Ha, pretty cool idea! It is like booting from a HDD without a HDD! :-D

trixster · 16 September 2020, 12:56

@alestanga CLI runs cli-startup (or shell-startup if starting Shell) in DF0:S/ which might then invoke a bunch of assigns or further commands (which also access stuff on the disk, likely commands in C: ), so without doing something like Eriond does you probably won’t improve cli load speed by putting it in Pi0:

alestanga · 16 September 2020, 18:28

thank you!
now my system boots from the floppy and then everything else run from the PI0!
it's so fast and silent compared to the floppy/gotek with buzzer.
now i have to mod the rev.5 mobo to get remoteWB, Video and sound device working.

alestanga · 16 September 2020, 18:47

i've noticed that there's a tap0 interface on the raspberry with the static ip 192.168.2.1
can i change that? it doesn't play well with my home network configuration.
or doing so would break something?
thanks

Yes certainly. In the file /etc/network/interfaces.d/tap0 you can set any address you like. The 192.168.2.x sub-net is referenced in the following places:

If you are not using the ethernet driver you can simply remove the file /etc/network/interfaces.d/tap0.

i've change the address in the tap0 config file in the etc folder and now i can reach my RPi just fine, but, if I were to change the address in all those files and recompile the ethernet driver, would it work with, let's put 192.168.3.1?

alestanga · 24 September 2020, 10:59

on saturday I've found an A500 rev.6 with the memory expansion in the dump.
I brought it home, cleaned the hell out of it, and now it works just fine.
I've configured it, with the help of Eriond, to have 1MB of chip ram (512K on the mobo and 512K on the A314)
yesterday I've ordered the 3.1 ROM (Licensed) not the 3.1.4 (albeit I like the number it doesn't have the workbench.library in ROM and I'd rather have it)
do you think it would be possible to install Workbench 3.1 on the RPi disk and boot it from the floppy like I do now with the 1.3 installation?

Made a quick video of the A314 working alongside the ACA500plus

Trying to trawl through the thread, I have a question.

Is it possible to Remote Desktop the Pi to the Amiga? Instead of Amiga WB to Pi.

nogginthenog · 04 November 2020, 18:57

There is an Amiga VNC server but it's very buggy.

What would be really cool is a Pic96 driver for remote monitors.
