Hi Lunix33 and welcome,

If you did not solve yet your problen, you could eventually check :
- for the boot :
- the sd is properly inserted
- the power supply is sufficient
- for the UART (but I suppose you are aware of these points and the tuto : https://forum.pine64.org/showthread.php?tid=6387)
- 150000 is indeed the appropriate frequency
- the rx of the uart is linked to the tx and the ground are wired
- the voltage is 3.3V
- flash the u-boot image in the spi and see if there are some messages sent by UART at power on even without any sd inserted
- if you have the opportunity, try with an emmc (boot method enabled in default) or usb boot (thanks to the u-boot)
good luck !
