Compute Module • Need help, ttyAMA0 does not work?

Hello, I am a beginner at this.

I'm using Pi 4 with Raspberry Pi Bookworm OS.
So basically I bought a GY-NEO6MV2 GPS module and I was going through a tutorial on how to use it, I'm on the step of checking if it works. Yes, the blue light on the module is blinking and I changed the configs inside the /boot/firmware/config.txt
I have entered :

Code:

dtparam=spi=onenable_uart=1dtoverlay=disable-btcore_freq=250force_turbo=1
In the /boot/firmware/cmdline.txt I replaced everything with :

Code:

dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait quiet splash plymouth.ignore-serial-consoles
I also backup cmdline.txt before hand and did reboot my Pi after all these changes.

Then I tried to run the following command :

Code:

sudo cat /dev/ttyAMA0
But nothing showed up, just a blank space.
Willing to learn and accept advices, thanks.
