Re: TK4- On a Raspberry Pi

The slow part was getting the SMP volumes built. I think if you followed Jay's instructions to the point where you had your starter system and SMP volumes built, you could move over to a Pi and be ok (and once you have those, you never need to build them again)... You may have a fighting chance on a Pi 3 or 4. One thing that was killing me was that I had compressed DASD, which was ****really**** slow on a Pi Zero when doing a lot of writes. |

Hi Mark, that might have been in a different thread with roughly the same subject. :-)? |
Re: TK4- On a Raspberry Pi
¿ªÔÆÌåÓýHas anyone done a full sysgen on one of these?? I am referring to following Jay Mosley¡¯s instructions. Assuming that you follow the Hercules install and compile instructions.?? I¡¯d assume it takes longer than on a much faster Desktop Linux machine ¨C but is it possible and has it been done successfully? ? Thanks, Dave ?

Re: TK4- On a Raspberry Pi
¿ªÔÆÌåÓýHi Scott,given the lack of reliability of SD cards when dealing with lots of IO activity/filesystem writes, I¡¯d recommend the use of an USB 3.0 attached disk to you. Even though a PI4 cannot completely boot from USB without the help of a boot image on SD, I think it is worth it. I use 512GB SSD ?disks¡° on both of my PI4. A beta of a new firmware that may have your PI4 boot directly from an USB 3.0 device is available, but I did not want to toast my PI so I¡¯m waiting until it is safe to upgrade. In the meantime, a redirect of the root partition in the /boot/config.txt helps. Kind regards Michael

¿ªÔÆÌåÓýChoosing the proper compile options make a huge difference, especially for the PI4, I daresay.?Kind regards Michael

Re: TK4- On a Raspberry Pi
Hello!
I can answer that one, try the ones at I find that site, and those stores to be in most regards, perfect. Although I am leaning towards the two I use here in New York. Although the Pi3 I have here and sometimes use was delivered as part of some sort of participation via Element14. ----- Gregg C Levine gregg.drwho8@...

Works well on a pi zero too!"well" is relative. Doing a sysgen from scratch on a zero was a multiday process that never completed; I finally did the gen on an Intel system, and moved my DASD over to the PI. It was ok. As I recall, getting the SMP volumes prepared was the really slow part; it's possible that once you had a starter volume and the SMP volume with everything ACCEPTED, doing a sysgen on a Zero would be possible... |
