   va_start (argList, START_PROP);
    cmdIndex = 4;
    while(NUM_PROPS--)
    {
        Pro2Cmd[cmdIndex] = va_arg (argList, U8);
        cmdIndex++;
    }
    va_end(argList);

U8 соответственно = uint8_t, и там это нужно, а мог бы задать uint_least8_t и обмануть, не разбираясь в сути.
А тут - такое...
Куда копать?
