I’ve tried the latest Minimal and Plasma Desktop images for Rock 3a with kernel 6.0.7-2 on an 32GB emmc from Radxa, and running “hdparm -tT --direct /dev/mmcblk1p2” gives me speeds around 40MB/s (+/-1).
When I run the same test with the official Radxa Debian, I get around 118MB/s.
When I use a microSD card, I also get 40-50MB/s with Manjaro. With other systems I get above of 60MB/s, but that is kind of in the same range.
All images were flashed with manjaro-arm-flasher.
What could be the cause and is there something I should look for in logs?
