I got a new Kindle PaperWhite 5 Signature Edition (2021) (PW5SE) that came with 5.14.3.0.1 on it. I opened it up (video if you want to see) and can't seem to find a serial port on it.

Has anyone worked with one of these? It looks like there's some kinda JTAG/eMMC connector on the back of the board in the FCC pictures, but they are too low res to make sense of it, and I didn't want to try ungluing that board. Same with removing the MMC chip to read it.

I have some more pictures of it up on my wiki.

I'm thinking this may use the USB C as a debug port, but thought to ask here if anyone has worked on this before. I'd say perhaps an OTG adapter and a FTDI port might work, but as this has to be in the bootloader, it needs to be real async port. Has anyone worked on this before?
