i use gcc 10.2, don't have ewl_c9x, how i can enable printf with uart port

Hi @alice_th,

You can use NewLib/NewLib Nano with Debugger Console I/O support with GCC 10.2:

or downgrade the toolchain version (6.3) and use EWL:

how to modify it when the project already created ?

BTW, if use GCC 10.2, we need still add uart driver code ?

like below code ?

but there is error , fatal error: ewl_misra_types.h: No such file or directory

#include <string.h>

#include <stdint.h>

#include <stdbool.h>

#include <stdio.h>

#include "ewl_misra_types.h"

#include "file_struc.h"

int_t __write_console(__file_handle handle, uchar_t * buffer, size_t * count)

{

(void)(handle);

uint32_t bytesRemain;

size_t bytes=*count;

LPUART_DRV_SendData(INST_LPUART1, buffer, bytes);

while(LPUART_DRV_GetTransmitStatus(INST_LPUART1, &bytesRemain) != STATUS_SUCCESS);

return 0;

}

if switch the gcc tool, then rebuild project, always have these error, what is the problem ?

Hi @alice_th,

No, that driver is for EWL console support.

I believe some changes are needed if you want to change an existing project's toolchain, such as the included paths in project settings, but I would suggest creating an application project and porting the application code to the new project.

if still use gcc 10.2, do you steps to add printf with console, is it only need configure,

alice_thanks_0-1713924091038.png

is there any other code we need add ? can you show the full steps with gcc 10.2 console printf ?

i want use the real uart print with terminal, you link only work with semihosting console.

i already add this code, but no print on my terminal, please check , thanks!

int _write(int file, char *ptr, int len)
{
uint32_t bytesRemain;
size_t bytes=len;
unsigned char ret_car[]={"\r"};
LPUART_DRV_SendData(INST_LPUART1, ptr, bytes);
while(LPUART_DRV_GetTransmitStatus(INST_LPUART1, &bytesRemain) != STATUS_SUCCESS);
LPUART_DRV_SendData(INST_LPUART1, ret_car, 1);
while(LPUART_DRV_GetTransmitStatus(INST_LPUART1, &bytesRemain) != STATUS_SUCCESS);
return len;
}

Hi @alice_th,

You can use the example you posted. This example was designed for an older SDK, which can be flashed in S32DS.2018.R1 or you can create a new project (selecting GCC 6.3 compiler and EWL library) and copy over the configuration from the original post:

Julin_AragnM_0-1714166809841.png

I've shared the ported project for S32DS3.5 RTD3.0.0.
