Compiling issue with SEGGER EMBEDDED STUDIO V6.30

[Sunil vignesh]

Hi,

  I am working with the nRF5SDK , nRF Thread SDKs long time. Recently i have update segger embedded studio to V 6.30 . previously i have used v5.68

1.

for nRF 5 SDK while build the ble_blinky example code  i got an error __vfprintf.h: No such file or directory

i found the solution that by removing the SEGGER_RTT_Syscalls_SES.c .and rebuild the code it is working

but i need the solution that without removing the SEGGER_RTT_Syscalls_SES.c how to build the project

because i need to work this project in both older / newer version of segger embedded studio

2.

also tried to work with nrf thread sdk 4.2.0 -thread_simple_coap_client_pca10056 . there i am facing same error __vfprintf.h: No such file or directory

while is remove SEGGER_RTT_Syscalls_SES file and rebuild the code i am facing some other errors

 
  Linking thread_simple_coap_client_pca10056.elf
    E:/nRF5x/2.thread_4.2.0/examples/thread/simple_coap_client/pca10056/blank/ses/Output/Debug/Exe/thread_simple_coap_client_pca10056.elf: TLS sections are not adjacent:
            TLS: .tdata
        non-TLS: .bss
            TLS: .tbss
    map sections to segments failed: bad value
Build failed

Hello,

I believe you already saw this thread, which discusses the upgrade to SES v6.2.0 and vfprintf() :

https://devzone.nordicsemi.com/f/nordic-q-a/85405/nrf5-sdk-17-1-0-examples-is-not-compiling-in-latest-ses-6-20a

I believe the same applies to SES v6.30.

BR,

Yes Edvin, I also mention here that only Ble SDK is working fine with that method not the THREAD SDK

example of thread protocol is not working by removing the SEGGER_RTT_Syscalls_SES  in project file

[Sunil vignesh]

I can't understand where to put this line #if !defined(__SEGGER_RTL_VERSION) ... #endif

and more over the removing of file is work out only for non ble_uart example codes

for ble_uart example even removing this file also it has same error SEGGER_RTT_Syscalls_SES  

[Edvin]

because i need to work this project in both older / newer version of segger embedded studio

Try changing the SEGGER_RTT_Syscalls_SES.c to something like this:

Note that I only added line 68 and 265 in this file.

Regarding 2:

Does that also fail if you open the same project in the old version of SES, or only the new?

Hi Edvin,

I have tried by changing SEGGER_RTT_Syscalls_SES.c as like you given but the error remains same even after i clean and refresh the project

regarding 2.

in segger version 5.68 it works fine only for the new version of segger , facing these issues
