That might be to do with the Repeat/Delay settings. They are sensible settings in the NC so auto repeat works.
If they are zero then the keyboard won't auto-repeat, and I suppose POWER-ON-Keypress would become POWER-ON-repeat-hammering-the-same-key-for-30-seconds (like you [still] have to do on a PC to get to the BIOS menu!!)
There's no battery on the NC and I don't think there is a CMOS chip. But the real time clock operates, and can be set and will keep ticking.
Any sort of reset however (even the softest of resets with SHIFT-BREAK) resets the CMOS settings to the power-on state, including the time back to Friday 2nd Jan 1970! So it's more or less impossible to do anything. RMASize is 0, so I can't run NCFresco or NCWriter, but there's no way to configure a size and then reset as it all goes back to nought. (ChangeDynamicArea didn't seem to work either).
And on the NC, there's no RISC OS line, when you get a Supervisor prompt, the "Supervisor" line is the top line on the screen.
The "Desktop" is just the grey screen with mouse pointer, no icon bar at all.
If I knew what a Bootp server was, and how to set one up, possibly I could make the NC boot into that and then get it loading all the missing bits of RISC OS so I can do something useful.

DHCP/BootP are basically the same -- your router will respond to BootP.BeebMaster wrote: ↑Wed Nov 09, 2022 5:41 pm If I knew what a Bootp server was, and how to set one up, possibly I could make the NC boot into that and then get it loading all the missing bits of RISC OS so I can do something useful.
I use DHCPD on a Linux server though, for more control. My NC then boots with a specified folder as its NFS mount...
Code: Select all
group {
host nc.home {
hardware ethernet 00:00:a4:11:b3:84;
fixed-address nc.home;
option root-path "/home/ian/RO";
option host-name "nc";
filename "/home/ian/RO";
}
}

Re: Another Bush internet.tv mod thread
The 'real time clock' is just a software counter that RISC OS maintains. This is the case for every RISC OS. It's initialised by reading the hardware RTC clock at boot time. So that fact you say "it operates" just means "RISC OS is running".BeebMaster wrote: ↑Wed Nov 09, 2022 5:41 pm the real time clock operates, and can be set and will keep ticking.
I've not had the NC out for years, but I believed it had an NVRAM chip, the same as @thecellartroll shows the STB does.

There are also two forks: https://github.com/barryc-ro/RiscOS_371/network
The "stardot" and "marutan" ones build on filesystems with long filenames (e.g. HostFS),
You'll probably want the fix for long filenames as it makes it easy to build on RPCEmu etc (with a 26bit OS).
But you'll probably not want anything from my 372 branch, as a) it might not work right b) it was just some tweaks to use some new sprites and a new font, but it used up nearly all the remaining freepsace in the rom.and the "marutan" fork also includes some stuff for a potential 3.72 build.

Re: Another Bush internet.tv mod thread
This seemed like an experiment within my ability. I can now confirm that mashing the Delete key on power on does reset the CMOS RAM but leaves the same (wrong) bits of it a messBeebMaster wrote: ↑Wed Nov 09, 2022 5:41 pm If they are zero then the keyboard won't auto-repeat, and I suppose POWER-ON-Keypress would become POWER-ON-repeat-hammering-the-same-key-for-30-seconds (like you [still] have to do on a PC to get to the BIOS menu!!)

Re: Another Bush internet.tv mod thread
Nice. I assume that's just a normal start, not a DEL-start... lots of big reads.
0x50 is indeed the address of the PCF8583, and two reads start from 0x10 which is the first section of standard RAM.
The flurry of writes at the end is funky.

Which would explain why it is starting with such nonsense in the CMOS RAM as it is not resetting much. I would have thought most of it should be writing. Perhaps DEL-Poweron doesn't work at all? Maybe it doesn't detect a keyboard at that stage.

Forgot to mention: no keyboard attached in the above test!
With a keyboard attached. Perhaps the iRDA interface is still messing with PS2?

Re: Another Bush internet.tv mod thread
It could more possibly be similar to the reason you can't DEL-reset an A4 with a PS2 keyboard -- the DEL-check happens earlier than the keyboard controller has got itself in gear to talk to the PS2 keyboard. I wouldn't actually have expected that on the STB though, as it's fine on an A7000 of course, but maybe timing is "off" a bit, or whatever, on STB hardware -- it's running a lil faster than an A7000+ of course (but the same as a Castle A7000+ Odyssey right?).thecellartroll wrote: ↑Wed Nov 09, 2022 11:59 pm Perhaps the iRDA interface is still messing with PS2?

Re: Another Bush internet.tv mod thread
The IBX board is under clocked to 48mhz. I believe the Castle A7000+ runs at 56mhz? There is a resistor mod possible on the IBX to make it run full speed.IanJeffray wrote: ↑Thu Nov 10, 2022 12:32 am running a lil faster than an A7000+ of course (but the same as a Castle A7000+ Odyssey right?).
Im confused why the data is showing keypresses when there is no keyboard plugged in?
Looks like I need to prioritise building the full CMOS RAM circuit with battery. I thought someone had made gerbers for a little board to replace the CMOS circuit on an A5000 but I can't find them now so was perhaps imagining it. This may be an opportunity for me to learn how to do that.
It will be annoying though if the IBX always drops to supervisor instead of just booting to desktop.

I'm "confused" why you think a load of "Keyboard: MAKE Unrecognized Key (0x00)" makes you think there are "keypresses" ?thecellartroll wrote: ↑Thu Nov 10, 2022 6:49 am Im confused why the data is showing keypresses when there is no keyboard plugged in?
I'm assuming you connected some of the LA probes to the PS2 bus, and told it to use a PS2 decoder for those probes?
There's nothing there, as far as I see. Look at the waveforms on a scope. LA's lie terribly. And this isn't even saying there's anything there anyway.
I'm not sure why you think you want this. Just so you can try and "hand correct" the configuration settings because DEL isn't working, then keep them? If you really want a battery, just put whang any old AA cell in with either a diode or a couple hundred ohms series.thecellartroll wrote: ↑Thu Nov 10, 2022 6:49 am Looks like I need to prioritise building the full CMOS RAM circuit with battery.

Exactly that.

Because I don't know how to turn a schematic into a physical board and the CMOS RAM circuit seems like a good place to start.

Re: Another Bush internet.tv mod thread
What's your LA sample rate set to? You may be missing clock pulses on the PS2 if it's lower than 4x the clock rate. Check the clock with the scope.
It looks like -way- more PS2 traffic than I'd expect to see.

Re: Another Bush internet.tv mod thread
I will poke it again later. I am still mighty suspicious of the IRDA which is obviously tied into the keyboard system somehow. Maybe I should hot gun its chip off to seeIanJeffray wrote: ↑Thu Nov 10, 2022 3:52 pm It looks like -way- more PS2 traffic than I'd expect to see.

Re: Another Bush internet.tv mod thread
IrDA is wholly unrelated to PS2. If you're probing the PS2 bus, you're not seeing IrDA traffic. It's more likely the IrDA is simply presented as on a standard serial port, as the STB doesn't have such physical ports.thecellartroll wrote: ↑Thu Nov 10, 2022 6:32 pm the IRDA which is obviously tied into the keyboard system somehow.

Looks like PS2 is too high a frequency for this LA to sample so all that can be disregarded.IanJeffray wrote: ↑Thu Nov 10, 2022 3:52 pm What's your LA sample rate set to? You may be missing clock pulses on the PS2 if it's lower than 4x the clock rate. Check the clock with the scope.

Re: Another Bush internet.tv mod thread
Hmm, it's supposed to sample at up to 24MHz, presumably on one input only. PS/2 is in the tens of KHz though, so it should be fine?thecellartroll wrote: ↑Thu Nov 10, 2022 8:09 pm Looks like PS2 is too high a frequency for this LA to sample so all that can be disregarded.

Re: Another Bush internet.tv mod thread
"it should be fine" means nothing if you don't tell us what sample rate you SELECTED.
And yes, that thing will do 24MB/sec ... all 8 pins sampled at 24MHz.
Re: Another Bush internet.tv mod thread
The Amazon blurb specifically says PS/2, too.

Re: Another Bush internet.tv mod thread
Yes, but it still depends on what sample rate was SELECTED. It can go UP TO 24MHz, but I almost never use it that high (pointless). It'll also go down to (may default to) something very low, so let's make sure it's at least a nominal 1MHz. It's likely, as the i2c traffic was kosher, and that 100kHz.

178 goes to pin 7 of the NVRAM.IanJeffray wrote: ↑Tue Nov 08, 2022 11:32 pm I'm going to guess that IOP[7:0] on the 7500FE map to S-space on the IOC. So where do pins 172..179 go ?
173 goes to unpopulated LK8 which looks like it connects that pin to 0v via a resistor.
The rest don't appear to be used at all, unless they connect to vias under the SoC - they don't seem to. The solder mask covering all the vias is an arse.

Re: Another Bush internet.tv mod thread
Is that the Alarm interrupt pin? Or address pin? Odd.
Anyway -- I was probably wrong about the IOP pins ... see IanS's post about nSIOCS2 ... trace that bugger.

Re: Another Bush internet.tv mod thread
No idea! nSIOCS1 and nSIOCS2 also have no track or via on the component side unless it is under the chip. We may need to lift off one of these SoCs and put it on your A7000 to find out what things are connected to!IanJeffray wrote: ↑Thu Nov 10, 2022 9:11 pm Anyway -- I was probably wrong about the IOP pins ... see IanS's post about nSIOCS2 ... trace that bugger.

Did you make a trace-finder brush like @mikeselectricstuff showed? Trace back from the CS on the modem eeprom.
