operating-system: After upgrade to 4.8 RPI4 don't boot with UART2 overlay

HassOS release with the issue: Hassios 4.3

Description of problem:

I had several problems after upgrading to version 4.8 from version 3.13. After several attempts I managed to isolate the problem. If in config.txt I ask to enable uart2 then the RPI does not even boot (black screen on the video in HDMI and activity led off). Simply by removing the uart2 everything works properly.

Questo è il mio config.txt

# For more options and information see
# http://rpf.io/configtxt
# Some settings may impact device functionality. See link above for details

# HassOS - don't change it!
disable_splash=1
kernel=u-boot.bin

# Additional overlays and parameters are documented /boot/overlays/README

# Enable audio (loads snd_bcm2835)
dtparam=audio=on

#uart2 on PIN 27/28
dtoverlay=uart2

Might want to wait to upgrade your OS to 4.8

Meantime Rollback done! 😃

For everyone:

Use the CONFIG USB KEY.
Download the old version .raucb from release page
Rename the .raucb to hassos-4.9.raucb (the version need to be upper to perform the process…) and put in the root of USB KEY.
Connect the USB key and reboot the host
…wait…
after the first boot remove the key
…wait… ( a lot! )

I saved the 4.8 image to perform test if a solution for UART2 is found.

I’m having trouble as well, tried updating to 4.8 from 3.13 and i can’t acces my RPI 3B+ anymore. I can only ping the RPI, no file acces via smb nor ssh via port 22222 works… guess i have to go with a new install…
