Raspberry Pi Zero (LTS) Armbian binaries with fixes:

1. TV output
2. H3 temperature readings

In the ZIP archive are updated kernel binaries. Unzip fist (due to GitHub files size limitation, archive is split).

Temperature is "low" even Opi Zero is in the Orange Pi black box with extension board inside. CPU has only passive small heatsink.

• 14:44 booted kernel with incorrect core temperature reading (executed htop, new kernel copy & installation).
• 15:09 booted kernel with temperature reading FIX.
• 15:20 start of packages installation.
• 15:37 started compiling of ffmpeg from sources (using 1 core).

• 16:53 performed make using 4 threads (to utilise all 4 cores), temperature rose (at peak) to 71 °C.

There is also activated DEBUG of h3 calibration value burned in chip.

In my case calibration value is caldata=0x07ed=2029
