BBoot on real Pegasos 2

I'm tryng to add BBoot 0.8 on real PEGASOS II without any success.
So due I don't waste time I ask for a support.

This is my startup cfg once firmware is started,.
BBoot is case n.5 and does not work, the Pegasos just reboots without letting me to start OS4.

Kickstart.zip contains all current Sys/Kickstart directory.

zip -r Kickstart.zip Kickstart/

Also for BBoot options it's not clear for me il these are commandi line options or not.

Any suggestion?

Haven't read all of the Forth in your script but looking at case 5 I see -initrd which is a QEMU option and does not work from Pegasos firmware. From Forth you should call bboot.fth not bboot which then loads bboot and Kickstart.zip but if you don't have those on hd:0 then you also have to replace that to the right partition in bboot.fth. This is documented in the BBoot README. So it should probably just be

5 of " /pci/ide/disk@0,0:0 bboot.fth" endof

Hi Zoltan,
thank you for your support but sadly I was not able to resolve, maybe I need a simple example.

Anyway I wonder if you can produce a BBoot binary not compressed in TAR but in an LHA archive to be easily usable by real amiga owners.
I loose a lot of time to look for a decompressor for TAR files using AmigaOS.
To get the binary I had to boot in Linux and decompress it on an usb pen.

In latest weeks I'm counting a lot of good news about Amiga world.

Maybe the following is one of the most important https://www.patreon.com/posts/one-more-thing-141985279

Michal Schulz is adapting Emu68k (running on ARM cpu) for a FAST PPC Core, much faster than QEMU.
What about mixing your great knowledge of AmigaNG chipsets with a new faaast PPC Emulator?

@flash
TAR isn't compressed at all (similar to lha -0 and the AmigaOS port of the Unix SysV tape backup and restore utility, C:BRU (not sure about the name, but it was included in some versions of AmigaOS), i.e. an uncompressed 1:1 copy of the data), only something like .tar.gz (.tgz), .tar.bz2, .tar.lzma, .tar.7z etc. is compressed data.

@flash
What simple example could help? This is written in the BBoot README:
Quote:
So does the "boot hd:0 bboot.fth" command work if you run it from the firmware prompt? If not then something is not as described above with the files or you don't have them on hd:0 partition in which case you need to edit bboot.fth as described above. Or if this command works then something is wrong with your boot menu script so figure out how to have it run this command.

BBoot dist file is tar.xz. Can't the xad based Unarc included with AmigaOS4 handle it? I haven't tried but there's an xadUnTar command so the only issue may be with xz but I'd expect this to be also handled by xad. It also has the Unarc GUI which I think is on the Dock by default so you could try if that works. I could do different format but tar.xz is quite common for a while to be generally supported.

How do you know Emu68k PPC core is much faster than QEMU? Have you run a benchmark on same hardware? QEMU linux-user emulation which is comparable to what Emu68k does is quite fast as it does not have to emulate MMU and a whole machine but that can only run Linux PPC executables on any other Linux arch. Emu68k has much narrower scope, only running on Pistorm so not much useful in QEMU. But QEMU allows different accelerators (e.g. you can use the same machine emulation with TCG or KVM) so it's possible to add other CPU emulators but it might not be easy to combine with Emu68k and if that's done would only run on ARM host. Also all my code in QEMU is under GPL so it's possible to combine that with other GPL sources as long as the result stays open source so if somebody wants they are free to do it.

@flash
I forgot one thing. On real PegasosII you may not see the logs from BBoot as it defaults to serial. You can change settings to log to firmware console as described in the README:
Quote:
The above was written before I've added fixups for PegasosII so maybe only change the output option for now as

to keep defaults but change output to firmware so you don't need serial cable for debugging. You can then tweak V (verbosity) option later but keep Apb where p is PCI setup that does 64bit BAR and interrupt fixups so you don't want to disable it until it's fixed by an update which Update 3 apparently does not but the changelog does not mention what actually is fixed in kernel. You can verify if the settings were done with printenv where you should see a bboot variable with the values you set and make them permanent with saveenv that saves it to NVRAM otherwise they are only valid for the current boot. The nodefault-bytes is only needed once to define the bboot variable, after that you can change the setting with only setenv.

Just tryed again.

I have setup all env from firmware

16 nodefault-bytes bboot
setenv bboot Of V1 Apb

please take note "saveenv" is not right command to save them

Kickstart.zip is created from my working AmigaOS4 partition with this command zip -r Kickstart.zip Kickstart/

Kickstart.zip is present on my BOOT partition.
bboot.fth and bboot are both present on my BOOT partition and loads ok!

On screen are printed some debug infos in very fast way, then screen goes black and Pegasos reboots.
No success.

Maybe latest OS4.1fe update (3) is incompatible with bboot 0.8?
..Are there other real Peg2 users than can test it with update 3?

About TAR archives, I just used preinstalled OS4 tools and your archive is not compatible.
If you want to refer to AmigaOS users you just simply to use LHA archives, this is my suggestion.
Linux is another world..

About Emu68k and PPC support, if you look inside my link you can read some tips from Michal Schulz and udestand why PPC emualtion under ARM cpus is so fast. the major part of instructions falls on 1:1 conversion and big number of registers present on both ISA let him to sppedup translation againt 68k one.

On QEMU TCG is slower because it's targeted on many cases and until this version (QEMU 10) for PPC all FPU part is missing.
All FPU math is made via SOFTFLOATS and so is MUCH MUCH slower.
You altready knows it.

Latest suggestion for all DEVS.. why not use OS4DEPOT as main repository for OS4 software? A lot of software is present on websites I can not read with current OS4 browsers and than I simply not use them, sorry!

Yes, me. I use bboot for year or so once balaton make it, starting from v 0.4 and now 0.9 or so. Always works with everything, and why shouldnt it : you only need properly call it with point out on ffs partition with zipoed ks folder.

@flash
I am also active Pegasos 2 user. Update 3 works OOTB here.
