![]() While imported projects will usually re-build with the external tool chain out-of-the-box, for the internal SEGGER tool chain based project build configurations, some manual changes may be required. On average this approach is less time consuming. All that is needed to do now is to add the sources from your Keil project to your Embedded Studio folder and fix Keil specific compile errors and eventually the linker script and memory map setup as described in troubleshooting. This way all Embedded Studio specific and target specific project settings are already in place. If you plan on using the internal SEGGER tool chain anyhow we recommend to skip the import tool and create a new project with the project wizard and if available with a CPU support package. For most projects switching to the internal compiler work out of the box, if it does not build out of the box please refer to section "Troubleshooting".Note: this feature is only available when using the internal compilers.After a successful build with the internal compiler Embedded Studio will automatically calculate how much flash and RAM will be occupied on your target device and represent it visually in the output window.The project will now be built when pressing F7 with the internal SEGGER compiler by default.This can be done by going to the Build-Config drop down menu and select the internal build config e.g.To use the full potential of Embedded Studio it is required to use the internal SEGGER compiler which is based on Clang.How to switch to internal Embedded Studio compiler debug features are not fully available when debugging code created with external tool chains. Note: While it is possible to only run the external configuration where the external tool chain is called, we recommend to switch to the internal SEGGER tool chain as some e.g. For most projects this will work out of the box, if it does not build out of the box please refer to section "Troubleshooting". ![]() To debug the example project with the Keil compiler choose "Target1_External" in the drop down menu and build the project by pressing F7.After that you have to set all the necessary user include directories to that startup files via: Project Setting -> Preprocessor -> User Include Directory's.So you will have to add them manually to you project via drag and drop. Embedded Studio has no information about the location of necessary startup files or Package files while importing the Keil µVision project.I think you guys do a fine job overall but this area is seriously lagging. PS: I'm happy to post a detailed note on how to get NewLib to work with ES. I cannot work out why the linker won't pick up libc.a when using Project Options->Linker->Additional Linker Options ![]() If I add libc.a to the project by adding the line below to the emProject file, I have no link issues. Here is relevant portion of the output from the linker:ġ> "C:/Program Files/SEGGER/EmbeddedStudio/gcc/arm-none-eabi/bin/ld" -X -omagic -eReset_Handler -fatal-warnings -verbose -LC:/Depot/Source/Library/arm-none-eabi/lib/thumb/v7e-m/fpv4-sp/hard -lc -EL -gc-sections -TC:/Depot/Source/32F401Disc/Blinky/Debug/Blinky.ld -Map Debug/Blinky.map -defsym=end=_heap_start_ -u_vectors -o Debug/Blinky.elf -emit-relocs -start-group -end-groupġ> opened script file C:/Depot/Source/32F401Disc/Blinky/Debug/Blinky.ldġ> =ġ> attempt to open C:/Depot/Source/Library/arm-none-eabi/lib/thumb/v7e-m/fpv4-sp/hard\libc.a succeededġ> Debug/usbh_cdc.o: In function `USBH_CDC_InterfaceInit':ġ> C:\Depot\Source\32F401Disc\Blinky\Middlewares\ST\STM32_USB_Host_Library\Class\CDC\Src/usbh_cdc.c:170: undefined reference to `malloc'ġ> Debug/usbh_cdc.o: In function `USBH_CDC_InterfaceDeInit':ġ> C:\Depot\Source\32F401Disc\Blinky\Middlewares\ST\STM32_USB_Host_Library\Class\CDC\Src/usbh_cdc.c:296: undefined reference to `free' verbose -LC:/Depot/Source/Library/arm-none-eabi/lib/thumb/v7e-m/fpv4-sp/hard So, I set Project Options->Linker->Additional Linker Options to: I put the NewLib library files on my machine at: C:/Depot/Source/Library/arm-none-eabi/lib/thumb/v7e-m/fpv4-sp/hard I also set Project Options->Libraries->Standard Libraries Directory to None. I turned off the ES standard library by selecting No for Project Options->Libraries->Include Standard Libraries. After much effort, I was able to get it to work but I ran into some issues I don't understand. I needed some new features of the C library and so I tried to get NewLib to work. ![]()
