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,

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

[Sunil vignesh]

Hi Edvin ,

This is how i am getting in two different Segger version V5.68 and V6.30 for both nrf5 sdk 17.1.0 and thread v4.2.0

1. ble_blink example nrf 5 SDK

V5.68

V6.30

2. ble_uart_example nRF5SDK

v5.68

V6.30

note: for uart example code the error is different and it is showing the retarget.c

Regarding 2.

nRF Thread 4.2.0

simple_coap_client example

V5.68

V6.30

[Edvin]

Hello,

Please try to contact Segger and ask them why the #if is not working, as this information is directly from them:

https://wiki.segger.com/Embedded_Studio_Library_IO

We only officially support the Segger Embedded Version studio up until the one mentioned in the release notes from that specific SDK, which is SES 4.12 in this case. 

BR,

Edvin

[Sunil vignesh]

Did you got no error while adding #if !defined(__SEGGER_RTL_VERSION)
in SEGGER_RTT_Syscalls_SES.c?

[Edvin]

I don't have Segger embedded studio v6.30 installed, because it is not a Segger Embedded Studio version that is supported in any of our SDKs.

If there was something that I could do to figure it out, I would have checked it out. You can exclude the file that includes the __vfprintf.h, and your project will compile, but if you want to use the macro that checks what version you have, we didn't make that, and I don't know how it works, and also I don't have anyone in Nordic that I can check with, because we didn't make it. So I think it is easier if you contact Segger and ask them why it is not working.

Best regards,

Edvin
