I am trying to get the LPC1768 to send a "Hello world!" message through its TX-RX pins, but the raspberry pi reports a buad rate of 0 when connected to it via TX-RX: What I've tried:

-. Disabling bluetooth and enabling uart in /boot/config.txt

-. Checking the pins in lpc1768 program, they are correctly set

-. Checking pins on the raspberry pi 4 and LPC1768, they are correctly connected, tx to rx, rx to tx, GND to GND

-. Disabling serial console connection, while making sure serial connections are enabled in raspi-config menu

Is there something im missing?
