UART examples nRf5_SDK_15.0.0.a53641 buid error

[melt]

Hi all.

all my examples for the nRF52840 DK 15.0.0 build correctly except for all the UART and serial examples which has 1 error

The error is "Conflicting types for 'put_char'                

the function with the error below :

int __putchar(int ch, FILE * p_file)
{
    UNUSED_PARAMETER(p_file);

    UNUSED_VARIABLE(app_uart_put((uint8_t)ch));
    return ch;
}

And it mentions that it was previously declared here

// Macro version of putchar.
#ifndef __PRINTF_TAG_PTR_DEFINED
#define __PRINTF_TAG_PTR_DEFINED
typedef struct __printf_tag *__printf_tag_ptr;
#endif
int __putchar(int, __printf_tag_ptr);
#define putchar(x) __putchar(x, 0)

Do I need to remove something?

Thanks in advance

hi.... melt 

To solve this error , you should do one change ........ change the type of value in ___putchar to _print_tag_ptr instead of FILE*

int __putchar(int ch, __printf_tag_ptr p_file)
{
    UNUSED_PARAMETER(p_file);

    UNUSED_VARIABLE(app_uart_put((uint8_t)ch));
    return ch;
}
