Rock 5b Plus and decklink sdi micro not work

Hi. i have Rock 5b Plus and m.2 capture Decklink SDI micro
driver setup ok
sdk from bleckmagic compile ok

but when i try capture or play video program not response and only hard reset (5V adapter tern off) help reboot

i use image t2 from radxa

Interesting card:


This sounds like power issues,
What ac adapter are You using? Any other accessories?
Anything left on console?

i use 5V 3A , i can try anothe AC adapter .
not Any other accessories
on console nothing - CTRL-C and CTRL-Z not work , in anothe console “sudo reboot” not rebooting rock5bplus

I don’t know this card much, but for two nvme 3A may be not enough on peak, usually sbc reboots or pcie device disconnects,

leave dmesg -w on one console and check out if there is anything in system log,
check device id with lspci and grep dmesg for any errors on init.
