Please add support for Keil
Hi, Since we have lots of libraries and code on ARM Keil tools, it would be very helpful if you could add support for it.
Please let the Pico team concentrate on what they should do. They don't have sufficient resources to add support for MDK.
For MDK support, please try this one:

Hi But you are under valuing the Keil tool chain, if you add support for it, I guarantee your sales would be boosted by 2-3X
Best Regards

That is a very ambitious claim since you don't actually know what our sales actually are...
We are looking in to alternative toolchains.
I've been using Keil for more than 10 years,and it's the standard tool for Cortex M development, and I know they have many users, also they have released the free version a few months ago, before that we had many many many users with cracks! So I think My guess is not that ambitious.
I hope you would assign some team members to add the official support for keil too.
Best Regards

I am also interested in Keil support as I am heavy user of Keil for STM32 and so on.
I tried some some you can find here: https://github.com/GorgonMeducer/Pico_Template
So some ground works is already done...
This is being looked in to. We do need support from ARM for certain things, which they will not be able to provide until the end of the year, unfortunately. In the meantime, lots of the toolchain already works.
Thanks, for the update, I hope we will see the official support sooner. Regards

I wonder if there is any update on this issue available.
@bgolab, The latest version of Pico-Template now supports flash downloading in MDK. Please feel free to have a try.
Dear Raspberrypi/Pico-Sdk Hi, Thanks for the update.
Best regards

We have now released an RP2xxx_DFP, which should work as a CMSIS solution for Keil tools. Feel free to give that a go and see if it works for you
Thank you for letting me know.
I wonder if you tested the PICO basic example (the one delivered within DFP) on Keil with Community Licence enabled: https://www.keil.arm.com/mdk-community/
I use fresh Keil 5.39.0.0 installation with the Community License activated as per the link above.
In my case I got to many compilation errors to proceed.
I wonder If you could share some details how this basic example was tested.
Thank you.
It has been tested in Keil uVision 5.39.0.0 with the Community License on Windows 11 and works fine, with no compilation errors. Did you install the DFP through the Pack Installer, and then copy the example from that?
The test process was simply to install uVision, use the Pack Installer to install the DFP, and then use the Pack Installer to copy the example and build/run it
Yes, I followed standard approach through the Pack installer then copied the basic example like I do for other MCUs like STM32. Win10.
Did you install all optional components available in the Pack Installer? I mean optional stuff like tensor flow etc? OR what minimal components are enough apart from DFP and at least CMSIS stuff...
Will try again then.
Thank you.
I didn't install anything other than the RP2xxx_DFP, so no other optional components. The example project has the required components for it selected by default, which are
- CMSIS
- Core
- Compiler
- Event Recorder (DAP)
- I/O
- STDOUT (EVR)
- Device
- Startup
- Pico Board (Pico)
- Pico SDK
The Event Recorder is just for the retargeted stdout so it can be read over the SWD connection
- I reinstalled Keil uVision (previously removed it).
- I removed ALL packs located at: C:\users%username%\AppData\Local\Arm\Packs
- selected RP2040 and install Rp2040 DFP.
- Copied PICO example
- added missing components automatically (CMSIS, etc). I do not see and Pack dependencies errors anymore.
I tried to compile the PICO example and got 92 errors with repeating sections like this: Build started: Project: rp2040_example *** Using Compiler 'V6.21', folder: 'C:\Keil_v5\ARM\ARMCLANG\Bin' Build target 'Pico' compiling env_wrapper.c...

Maybe your setup had some packs already installed - before you started Keil installation - when you remove the Keil uVisions the packs are NOT removed automatically...
The test process was simply to install uVision, use the Pack Installer to install the DFP, and then use the Pack Installer to copy the example and build/run it
I have just retried these steps on a clean Windows 11 install, and it worked fine, so I'm not sure what's causing your issues
@bgolab Which cmsis version do you use? Can you give us a screenshot about your RTE view.
I can replicate the issue you encountered. Please select cmsis 5.9.0 as a workaround. The issue you encountered is caused by the latest cmsis 6.0.0 and 6.1.0
I managed to fix the issue with the following changes:
After adding those changes, it is possible to get along with both cmsis 5.9.0 and cmsis 6.x.0
@GorgonMeducer Related to #1710 , or is that something entirely different?
@lurch Sorry, after double check, it is the same.
But there are something missing as shown here:
@bgolab @will-v-pi I have created an fixed pack, please have a try.
RaspberryPi.RP2xxx_DFP.0.9.5-dev.pack.zip
NOTE: this isn't an official release.
After install this cmsis-pack, you need to update the env_wrapper.h as shown below:
-
I use brand new Keil 5.39.0.0 installation, with CMSIS 6.1.0. The default installation. I cannot figure out why in my case I failed but in case of @will-v-pi (if the same CMSIS version was really used) everything is fine? What's the difference?
-
@GorgonMeducer Yes, selecting CMSIS 5.9.0 fixes the problem. Thank you.
I can confirm that I was using a slightly older installer of uVision, which still installed uVision 5.39.0.0, but defaulted to CMSIS version 5.9.0 rather than 6.1.0, which was causing the discrepancy. Will update the pack to work with 6.1.0
Edit: It looks like I was using the current version of the installer, it just installs 5.9.0 by default rather than 6.1.0 on my system, so I'm not sure why @bgolab gets 6.1.0 by default when I get 5.9.0?
Yes, in my case I had to install CMSIS 5.9.0 manually. The 6.1.0 was out of the box.
@bgolab can you check whether the cmsis-pack I attached could solve the problem or not?
so I'm not sure why @bgolab gets 6.1.0 by default when I get 5.9.0?
When people run pack-installer and see there is newer version of cmsis-pack, it is normal to click the update button.
And Arm recommends people to use the latest cmsis also.
I wrote earlier that CMSIS 5.9.0 fixes the issue.
More interesting problem - if you change the linker setting and try to link the code to SRAM area you will get some errors: _Build started: Project: test1 *** Using Compiler 'V6.21', folder: 'C:\Keil_v5\ARM\ARMCLANG\Bin' Build target 'Pico' linking... .\Objects\rp2040_example.axf: Error: L6915E: Library reports error: __use_no_semihosting was requested, but __user_initial_stackheap was referenced .\Objects\rp2040_example.axf: Error: L6915E: Library reports error: The semihosting _user_initial_stackheap cannot reliably set up a usable heap region if scatter loading is in use Not enough information to list load addresses in the image map.

@bgolab
I wrote earlier that CMSIS 5.9.0 fixes the issue.
I mean using the latest cmsis-pack (i.e. 0.9.5-dev) and work with cmsis 6.1.0
For the issue you encountered, please send the linker script you modified. Based on the error info from compiler, you might have removed the ARM_LIB_STACK
and ARM_LIB_HEAP
region in the linker script.
You can try this one:
