How to instal picore on RPi 3B+ from Windows

[mocore]

I wasn't aware piCore mounted the first partition as /boot like Raspbian,
I always thought it was mounted as /mnt/mmcblk0p1 by default.

Ah! i was also working from memory ,..
"boot_folder" not literally mounted @ '/boot'
but loosely meaning  "boot partition"   

the confusion i guess is mount points vs  partition labels ,
as you point out the first "firmware/boot" partition
is usually mounted as  /boot in Raspbian (the pi default os)   also labeled "boot"
and mounted at /mnt/mmcblk0p1 on picore by default!

For anyone else like me that's looking to get a CM3+ running with piCore.  I didn't really want to dive into using v10 as it's not released.  In a bit of poking I was able to use an exising 9.0.3 piCore image I had setup and just replaced the following files from the master of the raspberry pi firmware repo (link below).

overlays/*
*.dtb
bootcode.bin
*.dat
*.elf

(commit 9fd387c96353dd9983aa73bd33b541926de93789 in case it really matters)


Not sure how ghetto this, it but on a first pass all seems to be working. 

[Edit]: I clearly posted too quickly.  The single USB port doesn't even seem to recognize a keyboard, so not exactly a win.

Hi,
   I was trying to install PiCore 9.0.3 on a Raspberry Pi3A+ but only getting as far as the rainbow screen.

I see in these posts at there is a problem with version 9 and the Pi3 and suggestions to use version 10,
but I cannot find a link, on this page: http://distro.ibiblio.org/tinycorelinux/ports.html

Can anyone send me a link to version 10 or any version that will install on a Pi3A+ ?

Regards
