Hello Everyone,

I'm work= ing on a project with edk2, and these guys are trying to port edk2 to STM32= MP25 platforms. I have a problem with the module SerialPortLib, specificall= y the function SerialPortPoll. I made a test that adds a line of deb= ug in this function and adds a MmioWrite8 to a forbidden address=C2=A0 of m= y platform but I don't see anything. This demonstrates that I cannot ac= cess this function (this function is not loaded). Do you know why and how t= o solve this?

Here is my function SerialPortPoll
BOOLEAN
EFIAPI
SerialPortPoll (
=C2=A0 VOI= D
=C2=A0 )
{
=C2=A0 DEBUG ((DEBUG_INFO, "In SerialPortPolllll= lllllllllllllllllllllllllll\n"));
=C2=A0 MmioWrite8(0x80000000, 0xf= f);
=C2=A0 return FALSE;
}

And here i= s my function SerialPortWrite that works well because I can see the boot lo= g message
UINTN
EFIAPI
SerialPortWrite (
=C2=A0 IN UINT8= =C2=A0 =C2=A0 *Buffer,
=C2=A0 IN UINTN =C2=A0 =C2=A0 NumberOfBytes
)=
{
=C2=A0 UINT8 *CONST =C2=A0Final =3D &Buffer[NumberOfBytes];=C2=A0 while (Buffer < Final) {
=C2=A0 =C2=A0 // Wait until UART abl= e to accept another char
=C2=A0 =C2=A0 while (!(MmioRead32 (USART2_BASE = + R_UART_ISR) & (1<<7))) {
=C2=A0 =C2=A0 }
=C2=A0 =C2=A0 Mm= ioWrite8 (USART2_BASE + R_UART_TDR, *Buffer++);
=C2=A0 }
=C2=A0 DEBUG= ((DEBUG_INFO, "end SerialPortWriteeeeeeeeeeeeeeeee\n"));

= =C2=A0 return NumberOfBytes;
}

Thanks
