PZEM-004T With A6 on Serial

[Techno]

Howdy!

Thanks for the A6 Board, im using the second one already and i enjoy it.
I encountered a problem, connected PZEM-004T to Serial on A6 (GPIO12, 13)

When i power the board, it doesnt boot. I plug out the PZEM-004T from A6, it boots. I plug pzem back in. It works normaly, and i receive all the needed data.
What is the problem i have on boot?
