I have 2 HLK-LD6004 which are in continuous bootloop.
How to restore or reflesh firmware?

Below you can see terminal output from device:

Hello, pls try using 3.3V DC power supply first, if the module still in issue,pls feel free to contact us.

Hello,
thanks for your reply.
I tried powering the modules with 3.30V DC from a lab power supply, but it didn't change the behavior of the HLK-LD6004. The UART output is the same.

HLK-Ellen,
please, help to recover module.

Hi,Could you please measure if there is 3.3V or what is the ripple?
