Unable to read/write GPIO pins

Hello all,
I'm currently working on a project using upsquared board in which I'm trying to build a rover with four motors but before trying with motor driver I tried to check if gpio pins are working by glowing an LED, I tried to enable gpio pins using mraalib using these commands:
sudo add-apt-repository ppa:mraa/mraa
sudo apt-get update
sudo apt-get install libmraa2 libmraa-dev libmraa-java python-mraa python3-mraa node-mraa mraa-tools
following what's in this link: https://github.com/eclipse/mraa
but everytime I tried blinking the LED it threw this error:
File "/usr/lib/python3.8/dist-packages/mraa.py", line 392, in init
_mraa.Gpio_swiginit(self, _mraa.new_Gpio(pin, owner, raw))
ValueError: Invalid GPIO pin specified
no matter how many different pins I tried
So, I tried to rectify this error and found I have to update the kernel from generic to upsquared kernel as for this discussion: https://forum.up-community.org/discussion/4585/gpio-on-up%C2%B2
and when I updated the kernel and reboot the board to check whether the kernel was updated or not, it got stuck in bios settings over and over again everytime I reboot so I clean installed Ubuntu OS in the board once again and when I tried installing mraalib for gpio it says package not found and I don't know how to proceed, I don't think I should update the kernel because it may crash the system again

Do anybody know how to overcome this problem, any suggestions are welcome.

Thanks in advance.
