We're currently using the nRF51 from Nordic and while there are aspects of their SDK/release methodology that are a bit frustrating, they at least give you the option of using whatever compiler and development environment you want.

I wanted to try out some other vendors and started with the EFM32 series from Silicon Labs. From what I can understand, the SDK repo they used to host on github has been discontinued. Their suggested method forward is to just use their IDE and update the SDK files through that. I'm assuming you could just copy out the newer versions of the files you're using whenever you wanted to upgrade?

I had an old LPC17xx development board lying around as well and was also disappointed to see SDK support basically through community submissions. The LPCOpen library you can download is pretty terrible and is 6 years old at this point (at least in comparison to what I've been using with Nordic).

Now I don't know if I've just been spoiled by Nordic SDK support or if these manufacturers are just all trending towards "use our Eclipse clone IDE and that's the only option". If so, that's unfortunate. Are there any other manufacturers which aren't going in this direction?

Thanks for help.

I installed Simplicity Studio 3.3.
I clicked debug.
A box popped up saying I needed to get a Keil license and it told me to fill out a form. 
I filled out the form, and put the code I got from my email into the box, and it was displayed like the image.

Can anyone tell me what's up and how to fix it? 
 

Hi,

I have an existing project with existing, working build configurations that took quite some effort to get that way (i.e. correctly finding their SDK files, linked resources, yada yada, which seems to be an ongoing Studio pain point.) However, the working build configurations are for GCC 4.x. I would like to make identical copies of these but which use GCC 7.x.

I have read several existing resources for changing the GCC version, e.g.:

https://www.silabs.com/community/software/simplicity-studio/forum.topic.html/how_to_select_theto-E5Z5

https://www.silabs.com/community/mcu/32-bit/knowledge-base.entry.html/2014/02/25/simplicity_ide_chan-vY4k

https://www.silabs.com/community/software/simplicity-studio/knowledge-base.entry.html/2018/08/22/gecko_sdk_suite_tool-qlc4

However, all of these seem to depend on creating NEW build configurations from scratch, thus losing all of the painstakingly entered/repaired resource linkages and starting over. Indeed, following these instructions I am greeted not with a firmware binary but with pagefuls of:

fatal error: someprojectfile.h: No such file or directory

fatal error: arm_math.h: No such file or directory

make: *** [src/somefile.o] Error 1

Thus, I would like to change the GCC version of an EXISTING build configuration, rather than create a new one. Alternately, 'Clone' a current working GCC 4.x configuration and change (only) its GCC version.

1) Is there a way to do this?

2) During compilation, is there a way to determine which GCC version has actually been used, besides relying on the (possibly wrong) text created as part of the build configuration name? The console output doesn't appear to disclose any version information.

Thanks!

Hi, I am using a EFM32GG280F1024 chip on a custom board along with the starter kit STK-3700. I had used the STK-3700 as a debugger to program the chip on the custom board using the Simplicity Commander some time ago. It worked and the program for blinking an LED through a GPIO was working fine. 

Now when i tried to load a new binary file to the flash of MCU, the Simplicity Commander is giving me the error as shown in the attached figures. All the debug connections are in complaince with the instructions given in the AN:0043 (Application Note) and are same that worked in the previous case. 

The Blinking program that was loaded previously is still working fine but new program is not being loaded. Kindly help me figure out this problem.

Thanks

Hi,

With the EFM8BB1_LCK using the toolstick debugger chip, are there any plans to integrate the Toolstick Terminal in Simplicity Studio?

Currently it is impossible to both run a debugging session in Simplicity Studio and have a Toolstick Terminal session open.

I am using the BRD4001 board sn 161614298 with WGM160P

I try to use the energy profiler but when it start it ask to upgrade the J-link firmware

Current 0.14.3.471

but the upgrade procedure can't find the new firmware

Also from main page in simplicity studio the new firmware download fail

Hi,

Double clicking the .document file should open up the configuration dialog so that I can configure TX/RX toggling from what I understand.
My CP2104 is discovered as a "CP2104 USB to UART Bridge Controller" under debug adapters.

Created a Xpress Configurator project but cannot really follow AN721 fully. Something is missing for me.

We have the EFR32BG13 (BRD4104A Rev A02) housed on a Wireless Starter Kit (PCB4001 Rev 03), and are having problems -

Issue:

We are getting an unexpected part mixup and not sure why. When creating a new project for this, the board 'BRD4104A Rev A02' is not recognized in Simplicity Studio so we select the part 'EFR32BG13P632F512GM48' instead¹. This returns the following error report during a debug session attempt -

Hmmm, interesting. Ok, perhaps its right lets try the identified EFR32BG1B232F256GM48 it thinks it saw. With this selected we get -

What? We have the BGM111-A, BGM121 & EFR32BG modules also and they work as expected, what is wrong with this module?

Notes:

1. Chip top reads "EFR32 BG13P632HC 1849D00H07"

Greetings. I have a raspberry pi 3 (standard raspbian OS) in which it would be extremely useful to utilize as a development platform to be able to develop C code, cross-compile/build binaries, download, and debug on a EFM32 gecko microcontroller.

I was wondering if this is feasible, or if anyone has recommendations? I want it to be a standalone platform (for example: no remote terminaling into a more powerful Windows/Linux machine). It'd be very nice as well if I could use the established programming/debugging interface (SWD/ gecko eval kit set to debug out mode), but I am also willing to do custom bootloaders and such if necessary.

I don't suppose I can just install Simplicity Studio on the RP3? 

Hello,

           I want to build my Simplicity Studio project in a headless way from the command line. I am getting the following two errors

The project name and workspace is displayed correctly in the output. I have python v2.7. The code complies correctly in Simplicity Studio. Can anyone please let me know how I can resolve these two errors.

Hello There , 

i'm fairly new to silicon labs dev environment : i'm facing the following issue :

when i try to debug my project (which compiles and run fine under IAR ) i get the following message : 

simplicity_commander [ERROR: The connected device does not have a Secure Element (ID Code 63a02477)] 

 as i understand from documentation the secure element consiste of the second core on the chip responsible for handling rf stuff and auth , keys , siging , thus it's hardeware and it's part of the chip that's why i'm quite lost .

i attached the following screenshots which you might find useful 

Note : on IAR workbench i'm able to debug fine with no errors on lunch , same set up 

many thanks in advance 

best regards 

Aniss
