After careful analysis, the last line corresponds to "No Phy Found". The rest of the logs show a healthy boot and NAND. So I started looking at the PHY chip.
On the internet you can find this diagram:

So I unsoldered the part and ran the analysis, and the logs are exactly the same, confirming my point.
I'll order the part and keep you posted.
