STM32MP13 board not booting into FSBL

Hi, I have a board that I designed that's not booting and I am struggling to workout why.

I don't see any output on UART4 when booting and I also noticed that openocd reports the program counter as the following which I believe means that its still in the BootROM.

pc: 0x0000f738 .

I have built the image by using Yocto (St-Image-Core) and flashed it onto an SD Card.

I have attached the log file from the ROM Trace analyzer.

I do have a design issue where I failed to add a pull down onto OSC_OUT and I am using the HSE in Bypass mode, could this be the reason I am failing to boot into the FSBL when booting from an SD card?
