@jockneed your help.
I used your experimental Armbian images (5.19.15 kernel and libreelec patch). Of all, it works best with frequency DDR frequency of 666MHZ, but it still freezes. The idbloader.img firmware with a frequency of 333MHZ does not allow the TV Box to boot, and the reverse firmware of idbloader.img with a frequency of 666MHZ does not work either. (apparently you used rk3328_miniloader of a different version when creating idbloader.img).
I saved the bootloader from the your experimental Armbian image (5.19.15 kernel and libreelec patch) and recorded the ROOFS from Diet pi - TV box got off to a great start (with your DDR 666MHZ bootloader) but as soon as I connect the LAN cable, the box freezes. Tell me what could be the problem? Why do you think the LAN connection leads to a hang-up?
I tried to increase the voltage of vdd_log - but it doesn't help.
My RAM = D9PQL
Which version of rk3328_miniloader did you use in your Armbian images (5.19.15 kernel and libreelec patch)? - it work best with my DDR 666MHZ box
I want to understand how these boxes can be made to work at a frequency of DDR 666MHZ.
Can the LED control chip FD6551 affect the operation and cause it to hang?
