Inquiry Regarding I²C Clock Speed Configuration on UP Squared Pro 7000 Edge Box

Rakesh0815 — Thu, 04 Dec 2025 13:56:24 +0000

I am currently working with a UP Squared Pro 7000 Edge Box and need to adjust the I²C clock speed for an application that requires communication with a slave device at both 100 kbps and 400 kbps.
I followed the instructions provided on the UP Community Wiki https://github.com/up-board/up-community/wiki/Pinout_UP2#change-i2c-clock-speed , but I could not locate the South Cluster Configuration option in the CRB chipset menu.
Could you please confirm if updating the BIOS to the latest version will enable access to this configuration menu?

If a BIOS upgrade is required, could you please provide the link to the latest BIOS version along with detailed instructions for performing the upgrade?

Device Details:

Model: UP Squared Pro 7000 Edge Box
CPU: Intel N97
RAM: 4 GB
Storage: 32 GB eMMC

Current BIOS Information:

Version: UPN-ADLN01 R3.0 (UNASAM30)
Date: 08/23/2024

how can I change the i2c bus frequency from 400kHz to 100kHz?

Hello,
On an Up Board Squared Pro 7000 (upn adlni3 a10 1664) with BIOS version UNADAM28 01/01/2024 (updated by myself), I'm trying to force an i2c bus to 100 kHz.
I've tried to change it in the bios but there are no parameters to do so in HAT PIN configuration. So I updated the bios and it's the same thing, there are no parameters to change. I've added i2c_dw.force_bus_speed=100000 in the kernel command line, but the frequency remains at 300 kHz (confirmed on the oscilloscope). Is there any other way to change this frequency?
Thank you for your help.

Re-installing BIOS

vassefe — Sun, 11 May 2025 21:05:02 +0000

Due to an unsuccessful BIOS update, my UP Squared Pro 7000 system is bricked. Can I use my DediProg SF100 to reinstall the BIOS? Are there instructions on how to do this?
I appreciate your help.

NVME M.2 SSD card not recognised by UP Squared Pro 7000

vassefe — Wed, 14 May 2025 13:21:29 +0000

I have recently reflashed the BIOS of my UP Squared Pro 7000 system with the version UPN-ADLN01 R2.8 (UNADAM28). The re-flash was successful and I can bring my system up with the new BIOS version. However, the computer does not sense the NVME M.2 SSD card. Any suggestions on how to proceed would be greatly appreciated.

Is it possible to preconfigure BIOS for use without RTC battery.

Up Squared Pro 7000
BIOS says: UPN-ADLN01 R2.4 (UNADAM24) (08/28/2023)

Because I expect our devices to outlast the supplied RTC battery, I would like to preemptively disconnect the RTC/BIOS battery from the unit.

On some other embedded boards, we are given the option (and utilities) to preconfigure the BIOS settings such that there is no penalty when the RTC battery fails, or is removed. Essentially, we can specify the BIOS defaults from a working pre-configured board, save the settings as a new set of board defaults that are applied by default with or without a working BIOS/RTC battery installed.

Currently, I observe a significant increase in the time for the OS to start booting (Ubuntu) if I unplug the RTC battery, and I would like to avoid that.

Admittedly, I'm somewhat new to this hardware environment (though I'm comfortable with some other similar bits of equipment). So, it's possible/likely that I am missing something that would ease my concerns.

Please advise if I have any options to mitigate the impact of unplugging the RTC battery.

Booting OPNsense from eMMC or NVMe is unreliable

shaiku — Sun, 17 Sep 2023 00:28:21 +0000

It appears I have the latest version 2.1 BIOS. I'm able to boot OPNsense from a USB flash drive no problem but after installing OPNsense to the eMMC it will often dump me in the EFI shell (if I have it enabled, otherwise BIOS) on the first boot. Sometimes on a warm boot or after invoking the boot menu I can get it to boot to the eMMC, but not always. Every time after I reboot from the OS it fails to reboot to the eMMC.

I thought maybe the eMMC is having trouble with initialization so I installed an NVMe SSD and reinstalled OPNsense to it but now I cannot get the pro 7000 to boot to anything except the USB flash drive. Does anybody have any advice on what I can do next or how to better troubleshoot the boot problems?

How To Do BIOS_chip_flashing on upsquared pro 7000 ?

DRAM_tester — Fri, 25 Aug 2023 14:41:29 +0000

Hello, all
how can BIOS flashing be done in hardware on the upsquared pro 7000 ?

For upsquared there is a description here
https://github.com/up-board/up-community/wiki/BIOS_chip_flashing
is there a similar method for the upsquared pro 7000 ?

(
The BIOS image I would take from
https://www.aaeon.com/en/p/up-board-up-squared-pro-7000#downloads.
I do have a dediprog SPI programmer.
I make changes to the BIOS advanced settings CBR, for memory stress tests, so there is a risk I will brick the board.
)

Thanks a lot
JG

Ooops, Might have found answer already

then just a small difference in connector CN22 on upsquared pro vs. CN18 on upsquared pro 7000
