I've tried several recent releases back to bookworm, but the minute I turn apt loose to bring it up to date with a new kernel, in the last case 6.12.59, all /dev/sd* stuff disappears. WTH? I've been contributing to this project for several months

I tried on a RPI and it did indeed detect the OLED display. I forced the scan: # Force scan all addresses for i in {0..127}; do sudo i2cget -y 1 $i 2>/dev/null && echo "Device found at: 0x$(printf '%02x' $i)" done and it returned nothing

@Nick A hi nick i posted above my problem with x96q pro 2g 16g board , today i also noticed second usb port is not working.

I've checked performance of my old rk322x-based box (H2O with 1.5G RAM/4G ROM) and compared it with fresh, h618-based. sysbench shows that rk322x is ~20x times slower in CPU (rk322x - 39 events, h618 - 700 events) and 6x times slower in RAM operations (216MB/s vs 1333 MB/s). in threads test rk3222x is just less than 2x times slower (4317 events vs 7563 events). are these values OK? or maybe something is mistuned?
