amazing, just got it to work with my RED 15 (non-w) that I saved from the trash bins outside, it went through ice and rain, but still works!
Interestingly, I also couldn't get 23.05.5 to work (yet), it can't find the /dev/mtd* files, 23.05.4 works though.
Would love to know if there is some possibility of overclocking it, to get more than just the 650 Mbit/s
after a bit of searching, I found this :https://www.nxp.com/docs/en/user-guide/P1010RDBPBUG.pdf
where on Page 43 you can find configurations for adjusting the CPU Clock.
I tried some things with u-boot i2c, but due to my limited experience and knowledge I wasn't able to even find these parameters...
