Thanks Lawrence Angrave for your reply, here is your guess that you mentioned in your email (my answer below):
The frontend code setup wait logic can be found in sys-runtime.js. I'd guess it is this logic that will need to be tweaked. In your fork I'd start with this file- https://github.com/remisharrock/sysbuild/blob/master/webapp/src/app/sys-runtime.js
e.g. I see the 'wait requirements' here, which waits for the prompt to appear. this.sendKeys('tty0', '', '~ $', onTTY0Login);
this.sendKeys('tty1', '', '~ #', onTTY1Login);
Notice it waits for TWO terminals to be ready. Perhaps the new default jor1k instance only starts one, or maybe the settings use to initialize the terminal, stty -clocal crtscts -ixoff echo boot2ready-$?
are no longer valid with the newer jor1k build and returning stty is non-zero value.
Also the frontend code waits for the ready string "boot2ready-0" to be printed by both terminals before continuing.
Notice the communication with the kernel is
actually
through a simple narrow interface - just a serial tty. You may wish to instrument the initialization steps in sys-runtime.js using console.log messages to understand the setup process and find out why the extra returns are required. :-)Hopefully this is enough to help debug the problem.
I tried to do an almost empty sys-runtime.js that is available here https://github.com/remisharrock/sysbuild/blob/63dbfc7baa1d34289977e2d54bac142d8cdb2a3f/webapp/src/app/sys-runtime.js
As you can see, everything is commented except the
this.jor1kgui = new Jor1k(jor1kparameters);
and the jor1kparameters definition.
I still have the same issue that you can see here https://youtu.be/J_TxJck0kkw
In the video, you can see that error looping in the terminal.
ata1: lost interrupt (Status 0x58)
ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen
ata1.00: failed command: READ SECTOR(S)

To stop the loop, I have to press ENTER exactly 5 times, then the boot continues and finishes correctly:

I'm cross-referencing the bug here https://github.com/cs-education/sysbuild/issues/175 Narrowing the problem, hope I can get it fixed !
I cannot start the server to reproduce the problem. I get

Can you try to comment following lines in jor1k-worker-min.js please
7441 if (doze) { // doze
7442 doze = 0x0;
7443 if ((raise_interrupt|0) == 0)
7444 if (!(TTMR & (1 << 28))) {
7445 return steps|0;
7446 }
or try the gh-pages branch please. I guess it has to do with timing changes and the idle mode of jor1k.
I cannot start the server to reproduce the problem.
@s-macke Did you npm install
before gulp serve
?
@s-macke try the gh-pages branch : IT WORKED IT WORKED !! So happy! So it is the difference between gh-pages and the master branch (maybe the code you found in fastcpu.js right ? - have to do some testing if you want more detailed feedback) Anyway the problem is gone with the gh-pages branch !!
@s-macke It looks like if I use the master branch, even if I comment
7441 if (doze) { // doze
7442 doze = 0x0;
7443 if ((raise_interrupt|0) == 0)
7444 if (!(TTMR & (1 << 28))) {
7445 return steps|0;
7446 }
it does not work. But if I use gh-pages, it works !
I have reverted the patch and also updated some libs. I hope to get gdb running soon.
Hi, could you help me, I tried to use the newest version of jor1k with a modified version of cs-education and the bootup of jor1k is freezing until I hit multiple times 'ENTER' in the terminal.
Here is a video to show the freeze and how I have to type ENTER multiple times to finish the bootup.

Here is the source code:

and the readme to run the code:

Thank you!
