DiagROM for ST

[czietz]

You won’t get to the menu with broken ram. You should get that on the early serial port. Did you check that?

I didn't see that because the screen of the serial terminal was filled within seconds with a seemingly endless stream of crash dumps. Now that I have enabled logging into a file, I can indeed see that memory errors show up as "FAILED":

To use serial communication please hold down ANY key now

OR hold down the RIGHT mousebutton on the Amiga during poweron

Holding down the LEFT mousebutton will force serial on and turn off screen

forcing stuff to run in fastmem if avaible

This "Illegal Instruction Detected" debug data dump continues for a while.

Maybe the program could wait for key press when memory errors are found so that the user can actually read the serial output?

Either way this forum is not how you report bugs. (Because I only check the forum when Exxos pings me an mail to look at something)

Sorry, this wasn't clear to me. Perhaps you should add your preferred way of getting bug reports to the initial posting.

I’ll take a look at the illegal instructions. Mostly this was created for me to get my accelerators Woking on the ST but people persuaded me to release it. I didn’t design DiagROM though but I am familiar with it.

[terriblefire]

Btw I use putty for this so I just scroll up to see the history.

[exxos]

Maybe if its not detecting RAM amount correctly that is why its going a bit wonky if run on a 4MB machine ? I think your machine was stuck in 512K so could be why you are not seeing those issues ?

Hi TF, just a quick question, as is, will this boot from a cartridge on the STF? or will it need to be in the ROM socket?

I can burn some DIP proms which will fit the carts.

Yeah I saw that but wasn't sure if it would still boot before TOS or not?

[terriblefire]

It will work as a cart but that needs at least a working ROM to execute the first 10 instructions or so.

I am considering also echoing the console out to midi... would that be annoying or useful?

IMHO probably not worth going down that road.. at least not yet..

If it can be as well as serial then it can only help... the rs2s2 is a new circuit, and not tested, other chips may not be working either , so ACIA output stands a better chance of working right currently.

[terriblefire]

OK i just pushed an update that echo's to MIDI. I've not got midi in working yet so you need a keyboard or serial port to control it.
