I am using the UART1 of Omega2 - /dev/ttyS1 for GPS module communication with 115200bps.
It is 24/7 running for more than 3 weeks constantly.
Working with no error.
So I cannot guess what will be your issue on LTE board.
In my opinion, it is spidev (package name, kmod-spidev), as it is the working module on OpenWrt 22.03 build for Omega2.
I could see hardware SPI driver is present under /dev/spi* after installing it.
Havent tested it yet by myself, though.
@nsmith The patch files are available in the links I provided, just replace them in your system. The patch files are in the same directory as the make file, under a patches directory:
The patch files refer to the version so it's surprising the build is trying to apply them to the wrong version.

I wrote this for enabling all 5 ethernet ports for Ethernet switch.
But I think you can modify this for disabling all of them to use digital I/O, by modifying AGPIO_CFG.
@bilaljavaid01 the only place you are short on space is the ROM, Read Only Memory AKA you cannot write to it. So you actually have a lot of space available, but the installation is not using that space.
Step 1 look at python lite which is designed for low-resource devices, ie IoT devices like Omega2. Step 2, look at where the package is being installed and set up a symlink so that directory is linked to your sda2 device. For example, one of my apps used SQLite for a database which gets pretty large, so I create a symlink to /etc/<my app name>/data that points to /dev/mmcblk0p1 which is a 64GB SD card.
@luz my testing on OpenWrt 21 some time ago gave similar results, 90ish Mb/s depending on what services are running on the Omega2 at the time. My comments were an attempt to encourage the author to undertake a recognised testing methodology and report the results
@tonySP Since no one has chimed in on this, I'll share what I know.
I have a Huawei E8372 USB Dongle, branded Telstra here in Oz. The device supports 4G LTE and I have been able to use it on a VPN. I think it is discontinued by Huawei but Telstra still sells it here in Oz. There is an article on one of the OpenWrt forums that describes how to setup RNDIS using this device.
Not exactly what you asked but perhaps helpful.
