Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS (SEC BOOSTER)

As I understand from pictures: EmuTOS without Bus Errors has the same problems. So Bus Error behaviour on the hardware doesn't seem to be the cause. Let's focus on the last picture. sr=2700 means that interrupts are disabled, so the problem is very unlikely to come from interrupts. pc=0000c7c0: This...

Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS (SEC BOOSTER)

Apologies, those low PC addresses are normal for EMUTOS*.PRG. Such EmuTOS-RAM lives at $1c04. I'm looking at disassembly right now with the addresses of your screenshots.

Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS (SEC BOOSTER)

OK. NB: You don't need to go past the first panic(), because it is not supposed to crash at all. I'm still very puszzled that it can continue the boot after pressing a key at the panic screen... Very strange. So it crashes during snd_init(), which writes initialization data to the YM2149. Mainly, it...

Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS (SEC BOOSTER)

Thanks for your tests, Exxos! Every time, pc=very low value, which seems abnormal to me. I still suspect a jump to a bad address. Also, there are strange values in A0: last picture contains the soundchip address, previous one MFP... stuff related to hardware, every time. I still have big suspicion a...

Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS (SEC BOOSTER)

Damn. We will have to investigate that. I hope it's not an EmuTOS bug. However, I have never see such thing before.
Once again, be sure that no AUTO/ACC programs are loaded at startup. Best way is to tap Control key a the EmuTOS welcome screen to cancel all AUTO/ACC programs.

Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS (SEC BOOSTER)

The diagnostic cart tests all seem fine, other than first boot, keeps saying "I7 BUS ERROR NOT DETECTED" :shrug: Does this mean that your hardware doesn't trigger proper Bus Error when expected? That matters for EmuTOS, because it uses Bus Error much to detect optional hardware (Blitter, TT & Falco...

Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS (SEC BOOSTER)

Blank floppy with TOS104 loaded from ROM... Only emutos on the floppy nothing else at all. I have just tested the very same setup with Hatari and it works fine. It also worked fine on my real STe (TOS 1.62 + EMUTOSFR.PRG) How can it fail for you?? Maybe CPU, RAM, or other hardware issue?? PS: About...

Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS (SEC BOOSTER)

I just get this after loading the PRG.. nothing else.. Oh. That's very unexpected. Did you see the EmuTOS welcome screen before the crash? Note that some AUTO/ACC programs may not be compatible with EmuTOS. Be sure to press Control (just once) at the welcome screen to avoid loading any AUTO/ACC pro...

Actually still have same problem :cry:
Oh. So please start trying EMUTOSUK.PRG as I advised to see what happens.

Hey! Yes, but we both made some progress...
Oh, good news! This was a weird problem.
Feel free to ask if you have another strange problem, EmuTOS with debug traces can be very useful to debug things.
