I received two boards in December 2022 on both installed Armbian, I bought four power supply units with PD, since the board was rebooted with loads on the supply unit.
One board with a worker PD was used as a TV console with Kodi, and the second fee with PD as a workstation.

dpkg -l | grep rk3588

ii linux-image-legacy-rockchip-rk3588 23.02.0-trunk.0184 arm64 Linux kernel, armbian version 5.10.110-rockchip-rk3588 legacyPD stopped working only on one board with the same PSU models as on the first board
I try to install previous kernels, tried different SPI
tried to boot from Sdcard different images from radxa and armbian
But it didn’t work to get PD working again
What could be the problem ?
