Subject: Up Squared Pro 7000 (UPN-ADLN01) broken BIOS?
Date: Thu, 9 Jul 2026 23:48:38 +0300 [thread overview]
Message-ID: <alAJJr5ATEZdHBBA@ashevche-desk.local> (raw)
Hi!
Since I have been playing with the $Subject board, I wondering if I miss
something or the BIOS configuration is utterly broken. The problem what
I see is that most of the pins on the SoC are marked with [ACPI] if you
look at the debugfs 'pins' file for INTC1057:00 device instance.
This means *none* of them (which are user visible via HAT connector) may
serve as an interrupt resource to the OS. How the OS should request interrupts
on those pins?
As far as I understand that the BIOS does initial settings of CPLD and
basically I can use transparently the pins as per their configuration done
in BIOS. Right?
Btw, do we have any contacts to engineers in AAEON or whoever who does these
UP boards nowadays?
