WD Sandisk SSD, NVMe SA5xx - any UART mode or something?

[agrikman]

Hello dear engineers! Could you share your experience in researching the YODA board for the possibility of connecting via a dongle to a UART or in some other way to access the controller? There are 4 test points on the board, but they are all without power, the oscilloscope does not provide anything useful on the diagnostic connector, I must admit I have reached a dead end, please share your experience, what other ways are there to resuscitate patients? Thank you very much if you share your experience in researching this board.
