Pi1MHz Software

Yes, that was a new LUN - made by using the select command (equivalent of using the * command in the Util ROM) rather than doing anything to the SD card. I did it wrong actually, should have been 64 heads, so it only gives me a 256 disc!

Interesting I don't get bad FSmap while trying to read the defect list

BeebMaster · Post by **BeebMaster** » Sat May 28, 2022 8:44 pm

No, that was after a false start where I'd already tried formatting...it should be disc error &2C on a "fresh" LUN.

It would be interesting if the Adaptec Read Capacity command could be implemented, might give us a clue about what the controller thinks the disc size is straight after a format.

totally untested , but Read capacity may now work.

Can you confirm if the Pi1MHz software can run on either the Pi4, or the Pi Zero 2 W?

Thanks

dp11 · Post by **dp11** » Sat May 28, 2022 10:51 pm

Pizero2 is supported Pi4 isn't yet.

KenLowe · Post by **KenLowe** » Sat May 28, 2022 11:08 pm

I can't get the software you posted yesterday or today to run on my Pi Zero 2, but it runs ok on my Zero W and older Zero just fine. Is that expected behaviour?

The software on your github page seems to run on all three variants without any problem.

Okay I'll check pizero 2 and see what I have done wrong.

The latest version posted doesn't work at all, Pi1MHz SCSI isn't recognised.

This version works for me, when starting from scratch with the "Quickstart LUN" from the BeebSCSI website. I used the SUPERFORM provided in that LUN to create and format LUNs 1, 2 and 3 successfully.

(I did notice fwiw that the size of these new ones is 524172kb, when the original LUN 0 is 524140. No idea if that is a problem and/or expected, but it doesn't cause any obvious issues at least.)

It works ok here fwiw - I didn't do much with it mind, just booted up and moved around and listed a few directories on my drives.

(To be clear, I used the first beta provided, version 2239, to actually do the formatting tests.)

Thanks for the feedback. Latest version attached.

AndyGarton · Post by **AndyGarton** » Thu Jun 02, 2022 11:31 am

Thanks, do you consider that safe to use as a “release” version (I’ve currently reverted the two test versions above, even though they seem to work fine)?

dp11 · Post by **dp11** » Thu Jun 02, 2022 12:22 pm

Given I'm the only person to have tested this version like the community to have a play first just incase I have made a mistake. I can't see how I could have broken it, but i've said that before.

AndyGarton · Post by **AndyGarton** » Thu Jun 02, 2022 12:25 pm

Understood, I will try it as soon as I can and report back.

AndyGarton · Post by **AndyGarton** » Thu Jun 02, 2022 12:44 pm

All good here. I did noticed that a *CAT on power on on my Master 128 will hang, I need to do a Ctrl-Boot first. I think this might have always been the case though, perhaps related to the Pi not being fully ready?

dp11 · Post by **dp11** » Thu Jun 02, 2022 1:02 pm

Yeah the pi takes about 1.8seconds to be ready. I'm looking at speeding this up. But it's not easy.

I've not tried any of the formatting stuff, but other usual functions seem to be working fine for me on both Pi Zero and Pi Zero 2 W.

Thanks.

I just tried the latest version 220602 1100, but I still have the same problem with formatting, the verification goes on forever. Exiting out of it and writing an ADFS map & root and then verifying again solves the problem. So it looks like when it exits from the format call, it hasn't updated the size of the LUN in its internals, so the verify keeps going presumably until it falls off the end of the SD card.

BeebMaster · Post by **BeebMaster** » Fri Jul 15, 2022 5:04 pm

Not sure what it is really because after the format with verify being aborted, read capacity gives the right value, so somehow that isn't feeding into a "volume overflow" or "illegal address" error which should halt the verify when the disc capacity is reached, or maybe it's just not checking that the verify operation is reading outside the FAT LUN file on the card:

Also, can it set the number of sectors per track depending on the value of the Interleave at format please (as per Adaptec manual, interleave = 1 = spt 32, interleave <>1 = spt = 33)? Last time I looked at the code, it was hard wired to 33 spt all over the place (as seen in the capacity calc above, which is 1024 x 64 x 33).

In "Superform", you don't get a choice of interleave, it sets it to 5, so spt will always be 33, which is good for Winchester discs as it gives a bit more capacity, but for SD cards, since we can easily have the maximum ADFS disc size of 512MB, it makes much more sense to use a round geometry of 1024 cylinders, 64 heads and 32 sectors per track.

BeebMaster · Post by **BeebMaster** » Sat Jul 16, 2022 1:52 pm

I thought I would have a go at modifying the code to see if I can do something about the 32/33 spt thing, but first I wanted to make sure I could compile it, so I downloaded and unzipped the master, but when I try to use release.sh or build it more manually, I get this:

Anybody know what I am doing wrong?

sweh · Post by **sweh** » Sat Jul 16, 2022 2:05 pm

The "-fanalyzer" option came in with gcc-10. It's possible your arm-none-eabi-gcc cross compiler version is older than that (on my Debian 10 machine it's 7.3.1 so do doesn't understand it.

You can delete the -fanalyzer line from src/CMakeLists.txt to disable it, or you can upgrade your build environment. I dunno what the minimum gcc version recommended to build this is, nor whether code produced by older versions will work properly.

I think there's also an error in src/framebuffer.c ; it's trying to include MODE7Font.h but the file is Mode7Font.h so the #include line needs to be fixed.

With those two changes it compiled on my Debian 10 machine!

BeebMaster · Post by **BeebMaster** » Sat Jul 16, 2022 2:10 pm

I did download the ARM tools from the link in Readme.md but it looks like I already had some installed. What do I do with the new extracted tools - do they just get dropped into /usr/bin or somewhere?

I commented out

set( CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fanalyzer" )

from CMakeLists.txt and it let me get a bit further. Next problem was it said it couldn't find MODE7font.h because everything in Linux is case-sensitive, so I copied Mode7font.h as MODE7font.h and then it compiled, but I got a lot of warnings (this is a snippet as it wouldn't let me post the whole thing)

Compiled version doesn't work in my Pi1MHz, I just hear the Music 500 click repeating forever!

BeebMaster · Post by **BeebMaster** » Sat Jul 16, 2022 2:25 pm

Seems I have:

Code: Select all

gcc version 9.4.0 (Ubuntu 9.4.0-1ubuntu1~20.04.1)

but that this is also the latest version apparently.

I installed gcc-10 package, that didn't help, so then I downloaded this:

and extracted it and copied the bin dir into /usr/bin but now:

If I was gonna test this then what I would do is extract it to /opt/ to create /opt/gcc-arm.....whatever

Then I would do

Code: Select all

PATH=/opt/gcc-arm...whatever/bin:$PATH ./release.sh

That'll let the build process find the arm-none-eabi-gcc binary in that directory.

(That's assuming /opt is where the compiler should be installed; I have no idea!)

BigEd · Post by **BigEd** » Sat Jul 16, 2022 5:10 pm

BTW, I always use the env command to do that job, as it works in all shells AFAIK

Code: Select all

env PATH=/opt/gcc-arm...whatever/bin:$PATH ./release.sh

In either case, it's a good idea, as it only affects that one command (and all its children.)

dp11 · Post by **dp11** » Sat Jul 16, 2022 5:25 pm

my guess is arm gcc is installed in a different place to what is expected so the paths are wrong somewhere. nosys.specs lives in arm-non-eabi/lib

I've fixed the case issue with Mode7Font.h

But I still get hundreds of "warnings" and it doesn't work, just getting the Music 500 click and the Pi light flashing as if it's going round in an endless reboot loop.
