I'm having the same issue and have reverted to v4.58

The solution for me was to add: LIBRARY_IO_TYPE="RTT" to the .emProject file, in the configuration section. This was on line 31 for my project.

Thank you so much, it finally showed build success!

Once I understood, there should be 3 lines of #endif at the bottom @line 264

This is the proper solution for SEGGER_RTT_Syscalls_SES.c

you can only check for __SEGGER_RTL_VERSION after including the h file.

and remember to add #endif at the end of file (line 264)

#include "sdk_config.h"
#if !defined(RETARGET_ENABLED) || RETARGET_ENABLED == 0
#if (defined __SES_ARM) || (defined __CROSSWORKS_ARM)

#include "SEGGER_RTT.h"
#if !defined(__SEGGER_RTL_VERSION)

Another solution is to have RETARGET_ENABLED=1 defined.

Hi Einor,

Thank you the issue was how I removed the file from the project directory. I appreciate the quick response.

Hi Matt,

From what I can see, the only file in the SDK that includes __vfprintf.h is SEGGER_RTT_Syscalls_SES.c. So you really should not get this error when you have removed SEGGER_RTT_Syscalls_SES.c from the project. Looking at your log snippet it seems that SES is trying to find SEGGER_RTT_Syscalls_SES.c, so apparently it has not been removed from the project or perhaps something is cached so that you need to clean all build output and try building again.

Hi,

I am having the same issue running the newest sdk 17.1 and SES 6.20. When I remove the file SEGGER_RTT_Syscalls_SES.c I get an error:

Building ‘ble_app_blinky_c_pca10040_s132’ from solution ‘ble_app_blinky_c_pca10040_s132’ in configuration ‘Debug’[0m

3> C:/nRF5_SDK_17.1.0_ddde560/external/segger_rtt/SEGGER_RTT_Syscalls_SES.c does not exist.[0m
Build failed[0m

but when I do not remove the file I get the aforementioned issues already outlined here, namely, the vprintf.h issue.

I feel like I am in a catch-22 please help.

Regards

Matt

Hi,

The purpose of the file is to retarget printf etc. to RTT. Recent Segger Embedded Studio versions ship with this implementation as part of the toolchain so there is no need for the project to include it. The suggested preprocessor code that checks __SEGGER_RTL_VERSION is needed if you want to make the project compatible both wth older and newer SES versions. If that is not needed, you can ignore it.

I changed retarget.c:99 from

#if defined(__SES_VERSION) && (__SES_VERSION >= 34000)

#if defined(__SES_VERSION) && (__SES_VERSION >= 34000) && !defined(__SEGGER_RTL_VERSION)

Hi Einar,

I am also having the same issue while i builf "ble_app_blinky"

__vfprintf.h: No such file or directory in segger v6.20

when i delete SEGGER_RTT_Syscalls_SES.c file from the project it build successful.

I can't understand the purpose of this SEGGER_RTT_Syscalls_SES.c

where it will use while debugging ?

if i build the same project without SEGGER_RTT_Syscalls_SES.c in segger v5.68 . it build successful

where i want to use #if !defined(__SEGGER_RTL_VERSION) ... #endif

Thx for explanation

Hi,

There has been a change in recent Segger Embedded Studio versions that require you to remove the SEGGER_RTT_Syscalls_SES.c file from the project. With that, it should build as expected. For reference, this is mentioned in the Embedded Studio Library IO documentation:

Note: Older projects might include SEGGER_RTT_Syscalls_SES.c or a similar file to override printf(). When using the SEGGER Runtime Library, this file should be removed from the project, or its content should be encapsulated with #if !defined(__SEGGER_RTL_VERSION) ... #endif
