32 bit and 64 bit picore
« on: November 02, 2021, 07:01:36 AM »
Hello Forum,

could you tell me if 32 bit apps will run on "picore 64" ?

Indeed will "picore 32 OS" run on a 64 bit chip?

Thx

i mean it's to do with the instruction sets right?.....ARMv6 or V7?

piCore64 is pure 64bit, so 32bit apps will not run.

piCore and piCore64 will both run on RPi3 and RPi4.

OK Juanto,



My questions were pertaining to that new "Pi ZERO 2 W" board
which i believe is a 64 bit chip.

i know there are tons of 64 bit OS's available for it in the mainline.

all Ubuntu Latest builds are now fully supported on Pi's    (not beta anymore)

and there are many other 64 bit os's for Pi's

i wonder if "picore 64" will run on the "Pi ZERO 2 W" board?

it is very easy to get a 1.4ghz overclock fully stable on the boards
and so it makes it better.

Thx

C

Pi Zero 2 W is a cut down Rpi 3.

Yes it should run fine, you might need to grab the dtb file from the rpi firmware github and add it to the boot partition.

https://github.com/raspberrypi/firmware/raw/master/boot/bcm2710-rpi-zero-2-w.dtb

The config.txt will also need to be modified on the image as the conditional filter for the Zero-2W is

[PI02]

I'll have updated images posted soon, just waiting for RPI to stabilize some firmware naming.
