UART build error: "Bad value for formal 'sync_mode'. Must be a constant"

[Kratje]

Hi guys,

I'm making a matrix-based wireless MIDI keyboard for a uni project and the final hurdle seems to be an error PSoC Creator 4.4 gives when I try to build my project. It's already stated in the title, but here it is again:

Bad value for formal 'sync_mode'. Must be a constant

The line this refers to, however, is in the official PSoC UART peripheral block, which for obvious reasons I shouldn't be asked to edit.

Attached are a screenshot of my TopDesign, my main.c and the line that causes the error. Does anyone know what causes this?

Thanks in advance!

#include "project.h"

void setup(void){
    scannerPWM_Start();
    UART_1_Start();
}

int main(void)
{
    CyGlobalIntEnable; /* Enable global interrupts. */'CY8C5888LTI-LP097
    /* Place your initialization/startup code here (e.g. MyInst_Start()) */
    setup();

    for(;;)
    { 
        /* Place your application code here. */
    }
}

//interrupt to send midi
CY_ISR(tx_go){
    UART_1_PutChar(Status_Byte_Read() );
    UART_1_PutChar(Note_ID_Read() );
    UART_1_PutChar(Velociy_Data_Read() );
}

Hi,

Your "error.png" seems to suggest that the defined value "TRUE" has been defined not as a constant.

As far as I tried to trace, in cy_psoc3_inc.v, TRUE was defined as

`define TRUE 1

But may be you have another definition of "TRUE" in your project, which could cause the error.

If it's not the case, I can not think of a good reason.

Posting your project or a minimum project which can reproduce the error could help others to find the cause.

Hi moto,

Thank you so much! You were completely right. My VHDL to Verilog translator had inserted a few lines at the top that defined 'TRUE' and 'true' as binary values for whatever reason (it didn't even use them in the generated verilog).
