I flashed it tonight, I ran one of balbes150’s Armbians with the 5.3.0-rc6 from USB stick.
I attempted to run the aml_autoscript from the update app in Pie, when it reboots, it throws sig verification error. So I used the keys.
The first time booting the stick from the VIM3, I had to use the keys. After that, all it took was connecting the flash drive and it boot to the Armbian stick without using the keys. Not sure if that represents the changes you mentioned.
The results of comparing the values of the Antutu test readings of two firmware:
Antutu test VIM3_Pie_V190809 - 132700
Antutu test VIM3_Pie_V190907 - 98000
Yes, unfortunately, this is true. I can’t show screenshots, but you can ask any person, he will confirm you. You can do the tests yourself. Superceleron has the same situation: in firmware 1 there were more than 130 000 points, in the latest version 2 - 95000.
