Iam migrating from Keil IDE uVision version 4 to version 5. I amtrying to create a new project using the NXP LPC4357 targetmicro-controller. This was listed as an option when selecting thetarget device for this new project with version 4. But alas.....it isnot listed as an option when creating a new project using version 5.It is listed in the Device Database (File > Device Database) inversion 5, but when exploring the device availability in the PackInstaller, I have discovered that it is not listed. I did, howeverfind the LPC18xx listed.
I am asking for some assistance to point me in the rightdirection. I prefer not to create a custom target. I expect that thedevices supported in Keil IDE uVision version 4 to be available to me(somehow) when using the Keil IDE uVision version 5.
Concerning LPC43xx support:
I also have installed the legacy pack for uVision 5. I can't seem toget Manage Run-Time to install components (resolve issues). I needmiddleware, as a trial I selected USB device CDC and get errors.
using the legacy packs does not stop you from using the PackInstaller. The only difference is that you'll see a lot more devicesin the first dialog "Select Device for Target". The ones that areshown in grey are coming from the legacy packs and will use the oldflow, no Run-Time Environment. The ones that are shown in green arecoming from the Device Family Packs (as installed by Pack Installer)and are using the new flow.
if you are using the legacy packs, you need to use the old flowfrom uVision4.x. This means, you can neither use the Run-TimeEnvironment nor the new Middleware. You will need to stick to the oldRL-ARM middleware, which can be found in the same places as before.Also, use exmaples from the C:\Keil\ARM\Boards\Keil\MCB4300\RL...directory.
all:I updated my keil MDK version to the latest which is V5.37,and then I found that the project can't build anymore.since the V5.37 do not support the compiler 5 and set the default compiler to compiler 6,I installed the compiler 5(Arm compiler version 5 ,V5.06 update7) with a independent patch.and then add the compiler 5 to the keil,set the compiler 5 as the default compiler,but keil can't build the project,build output as follows:
When using Keil ARM Compiler version 6 to compile the code, I am observing several concerns, possibly because the FreeRTOS-Kernel code is still compilable with help of Keil ARM Compiler Version 5 and not with Keil Compiler Version 6.
I have made modifications to the files and brought them up to a level wherein the compiler is now not throwing errors. I however need your help with how to correctly use the extern variables inside the ASM code . I am also concerned about how to handle C variables in assembly.
May you please help me with the path for the GCC files for Keil. Maybe I added incorrect reference to files that I am using, as I was not sure where to find the exact Keil Compiler related files on the GitHub / FreeRTOS Kernel.
I did review both the base files and they are indeed coded for compiling with help of Keil / ARM Compiler Version 5. Also as I am sure about the current compiler being supported, I tried modifying the two files so that the files can be compiled with help of ARM / Keil compiler version 6.
As I am developing code for STM32H753BIT6, I used STM32CubeMX to configure the microcontroller and also enabled FreeRTOS in the tool, so as to get the FreeRTOS (version 10.2.1 with CMSIS-RTOS version 2.0) port for the microcontroller
I have recently installed MQX classic and Keil Ver5.22. I have a few reference projects with Keil Ver4 and MQX 3.8. I am able to build these reference projects. I need to port these projects to MQX 4.2.2 and create new projects for my current usage(this is my concern).
MQX supports Keil and was compiled and tested with Keil uVision version 5.14.0. The RTOS in run time environment you mentioned maybe refers to some pre-built libraries. For MQX we have separate software package MQX 4.2.
For creating project, I would suggest you use BSPCloningWizard tool , which provides an easy way to make copies (clones) of BSP files and projects. You can start with the cloned project. This tool supports Keil
The Keil uVision software that comes with the CY3684 is a demo version and it cannot build project file that exceeds code size of 4kB. You can install the full version of Keil software from the below link to build the same.
Finally, if you want to proceed with the build on uVision MDK-Lite version 5.37 or later, you must install the compiler appropriately in the path. If you have uVision MDK-Lite version 5.37 or later, follow the compiler download process below.
Pressing this Download link button will take you to the screen similar to the one in the picture below. Click on the "Download Now" button to download the file. Since a login is required, log in before proceeding.
Spring 2023 example code has been tested with Keil uVision IDE version 5.38a, and we are writing software in C99. Any version of 5.xx should be ok. These programs only run on Windows 10 or 11. There is a way to install software on older Macintosh computers so Windows and its applications will run on the Macintosh, see running Keil and TExaS on a Macintosh. However, there is no solution to running Keil on the newMacintosh computers with the M1 processor, because there are no OS driversfor the Stellaris ICDI debugger.Macintosh users with the M1 processor can write software on CCS.We are really sorry, but there are no solutions for Linux. The Keil application does not require a serial number or license key. It is possible to install both Keil uVision 4.74 and Keil uVision 5.38 on the same computer.
Step 1) How to install Keil uVision for the ARM, MDK-Lite (32KB) Edition. Go to Enter your contact information with valid address, phone and email. Set your Company to the University of Texas at Austin. Set your devices to the Texas Instruments (TI) and Cortex-M4. Fill in all fields of this form. It should not cost any money, and you can select or not select whether you want email from ARM. ARM does provide support for Keil via its ARM University. So if you have any Keil-specific questions you could register and post them at
Step 2) Right-click on MDK538A.EXE and download this 887M file to your computer.
Step 3) Execute the MDK538A.EXE file, installing the application some place easy to find, like C:\Keil or D:\Keil. You will need to find the Keil directory because the TExaS example files will be loaded into this same directory. After you have run the MDK538A.EXE installer, you will not need this file. However, you can use this file to install Keil on additional computers.
A slide show of the process to download and install Keil 5.21a can be seen at slide show.

Guessing here based on symptoms. Your Keil uVision license is code limited to 32K? I suspect your settings for optimization are higher (O3?) than what the mbed settings are (O0,O1). Poke around in your uVision and see if you can turn down optimization and see if it results in the same error message. Somewhere in the Python scripts I bet they are calling uVision with a list of external flags - one of which is optimization...
I think you are right, so I've switched to GCC_ARM instead as its free. Thanks for the info, I had assumed that my uVision didn't have a limit, but at some point I ended up getting the same error when compiling in uVision. I now have a working version of the mbed source for my stm32f413zh board :)
You might also try the STM System Workbench for STM32 if you're focused on STM products. Well integrated GCC environment. The generic GCC is great as well if you're up to speed on all the gotchas for integrating a compiler and debugger on your own.

I was planing to use ARM Keil MDK lite edition as it is free and compatible with commercial products (with a 32Kb limitation). Of course I would like to use the latest version of the SDK to have the latest features and bug correction. From my understanding, the last version is v6.0.20.1338 (v6.0.20.1338 release note).
I don't really understand this warning. Did it means that I don't have the possibility to use the latest SDK (which is not conceivable for me) or did it means that I have to use the (not included) compiler version 5?
I have tried to build an example from the latest SDK 6.0.20 with the included ARM compiler (v6) and as the guide tells us, the LTO option prevents us to build it. But if I disable this option the project builds.
Hi Olivier,
Thank you for posting your question online.
In order to develop your application with DA14531 you will need Keil MDK IDE.
SDK v6.0.14 and SDK v6.0.16 use ARM Compiler v5.
SDK v6.0.18 and SDK v6.0.20 (which is the latest SDK release) use ARM Compiler v6.
The DSPS SDK use ARM Compiler v5. The next version of DSPS SDK is going to be released in ARM Compiler v6.
The Codeless SDK use ARM Compiler v6 and exceeds the 32kB limitation.
ARM Keil MDK lite edition has the 32kB limitation (which will stop you from testing specific examples) and does not offer the Link Time Optimization option.
ARM Compiler v6 requires the LTO option for the most examples.
On the DA14531 you can load a firmware up to 48kB, but with the lite edition you will not be able to create a firmware over 32kB.
Now let me try to answer your questions:
