![]() Included Embedded Software (Object Code).Start programming your application immediately and rely on The Embedded Experts to answer any questions during your development. This streamlined package works out-of-the-box. If source code for the RTOS and other embedded software components is desired, please contact SEGGER to learn more about the possibility to upgrade to full source code. It includes a powerful integrated development environment (Embedded Studio), a complete embedded software suite in object code form, and the industry leading J-Link PLUS debug probe. Source code which uses it must be updated to be compiled with Embedded Studio V5.Embedded Studio PRO is an all-in-one embedded development package. Older versions of GCC and clang supported both.Ĭlang-11 and segger-cc 11 (as included in Embedded Studio V5.20) do not support the use of '$' anymore. While '$' is used in i386 asm, the arm assembly syntax only defines the use of '#'. Some legacy code used '$' instead of '#' for immediate values in inline assembly. This error message is rather cryptic, but its reason and solution is as follows: PLEASE submit a bug report to and include the crash backtrace, preprocessed source, and associated run script.Ġ. :2:2: note: instantiated into assembly here SEGGER_RTT_Conf.h:158:73: note: expanded from macro 'SEGGER_RTT_LOCK' SEGGER_RTT.c:730:3: error: unsupported relocation on symbol :1:2: error: unsupported relocation on symbol Troubleshooting Error: unsupported relocation on symbol When using an assembler project with the new linker script file make sure the following file is also included in your project /samples/SEGGER_crtinit.s Make sure this is done after setting up heap. Initialize by symbol _SEGGER_init_heap // Call constructors for global objects which need to be constructed before reaching main (if any). The most important change is that the following two lines need to be added to the initialization block: The new linker script can be found under /samples/SEGGER_Flash.icf if you are using a Flash based project or /samples/SEGGER_RAM.icf if RAM based. If you are using RTT sources in your application, make sure the SEGGER_RTT_Syscalls_.c file is removed.Īlso make sure to set the correct I/O type for your project in project setting Library I/O. ![]() To use the new SEGGER run time library the following project option must be set: Code->Library->Run Time Library->SEGGER Additionally set the project option "Starting Stack Pointer Value" to _stack_end_. For this simply edit the Startup.s file as explained in the sources comments. ![]() But if you would like to set up a RAM debug project you can set it manually. Note: Generally the initial stack pointer is not set as this is usually done by the hardware. Note: The preprocessor define MEMORY_INIT has changed to _MEMORY_INIT. Note: When setting up a RAM debug config with the sources provided via CPU support packages please note that the preprocessor define for the VTOR config has changed to _VTOR_CONFIG. ![]() You can find the latest version of this file in your Embedded Studio installation folder under /samples/Cortex_M_Startup.s and /samples/SEGGER_THUMB_Startup.s 5.1 Error: unsupported relocation on symbolĭue to improvements on how the SEGGER toolchain handles the target startup code the Cortex_M_Startup.s and SEGGER_THUMB_Startup.s must be updated.
