Hello everyone! I have a UP Xtreme i12 Edge. I have put internally the sim card. The I have installed ubuntu on it. Digiting "mmcli -L" it said "No modems were found". Do I have to do something in the hardware? I have to program the 5g sim

Why doesn't Up Xtreme i12 i7 recognize m.2 2280 ssd NVMe?

buddye — Sun, 18 Jun 2023 14:54:06 +0000

We just received the new 12th gen Up Xtreme i7. It does not recognize the Western Digital WD - BLACK SN770 500GB Internal SSD PCIe Gen 4 x4 that I plug in. I've plugged this into both of the M.2 2280 sockets, no recognition.

This same SSD device works fine in our older Up Xtreme i7.

How can I diagnose this problem?

Thank you,
buddy

SPI cs1 doesnot operate

hyunbin — Fri, 03 Nov 2023 03:53:04 +0000

I am using up xtreme i12 and i have to use spi communication.
When I use my code in upboard, spidev2.0 spidev2.1 were operated well.
But, in i12, when I input ls /dev in linux, there are spidev1.0 and spidev1.1. so I used that devices,
However, the cs0 pin operates well while cs1 pin does not operates. when I used oscilloscope, the cs1 pin always show low state.
How can I use cs1 pin? is there any problem at pinctrl. deb ?

Dear all,

Thank you for your support.
We built the Slimboot and reprogramed the SPI flash by Dedi Prog SF100 for UP XTREME I12.
The UP XTREME I12 was booting with slimboot, but we couldn't install Linux OS on the it.

If you know, tell us how to install OS with slimboot for UP XTREME I12?

Best Regards,

GPIO UART1, GPIO Interrupt

hyeonwoo — Thu, 25 May 2023 11:55:39 +0000

hi
i would like to use ntp time sync from gps message(GPRMC, GPGGA) in Ubuntu 22.04.
there are some problems using GPIO UART1 and interrupt settings

problem 1. UART1 is not working
i tried GPIO14, 15 as UART input but no message came out from ttyS4

(UART0 (10 pin, ttyS5) -> working good)

problem 2. interrupt is blocked
i tried linux kernel module setting GPIO as /dev/pps

it fails in the process of registering the interrupt (register IRQ)
dmesg said "pin XXX cannot be used as IRQ"

(link: https://github.com/Jobbel/pps-gpio-dtless)
(both upboard pinctrl driver number 0 to 26 and sysfs 6XX~1001 failed)

The chip on my Up Squared V2 burnt out, but I don't know which chip it is.

I'm sorry, I put it in the wrong category. Actually, what I have is an Up Squared V2.

I have an Up Squared V2 that I use as an ROV controller. It was running really well until today when I unplugged the 12V power cable, as recommended. When I reconnected the power cable, the IC chip burnt out. I don't know what the IC is or what caused it. I have attached a picture below.
