Mbed OS Bugs

Hello,

I have been developing code on ST’s Nucleo- L476 board based system. I use a desktop and laptop since 2021 and mostly using mbed-os - ver 5.0

Recently I wanted to cretae mbed studio IDE in a laptop running Windows 10 so I installed installername: MbedStudio-1.4.3.exe . Next I copied whole workspace from desktop in laptop.

When I opened IDE and workspace, I could see all files correctly. When I pressed Build button, I got a series of error messages, whose summary was Failed to check out a license. the full error message is pasted at the end of this post.

I opened libraries and it shows os ver as 6.17.0

I tried to add library and gave URL for OS ver 5 such as “GitHub - ARMmbed/mbed-os: Arm Mbed OS is a platform operating system designed for the internet of things” but it gave error. I gave another URL pertaining to OS 5 but that returned that folder is empty.

Please help me to get ver 5.0 I am using some of teh old version verbs such as wait() or class Serial that are not supported in ver 6.xx

Hello,

I was able to open Libraries card and using add Mbed Library, managed to download OS ver 5.15.3-rc1^2. I used check out method to remove existing ver 6 and download ver 5.15.I hope whole of ver has been removed from workspace.

When I built program, it still gives a similar error. It still shows ARM 6.15 compiler being used. the error message is as follows:

Hello,

You can ignore this, it doesn’t have anything together with MbedOS version. However the installation contains also approx one year licence (date limited not from installation) for Arm Compiler 6 which is not free in normal way. And that lead us to the root cause because latest version seems to be 1.4.6 - Installing Mbed Studio - Installing | Mbed Studio Documentation.

BTW do not miss - Important update on Mbed - End of Life - Mbed OS - Arm Mbed OS support forum

Thanks for reply. I am seriously considering migrating to other IDE such as Arduino.

In the meanwhile, how do I get os 5 running on a new laptop? Will it have Arm Compiler 6? If so and if it is not free then how do I pay for its usage?

I believe I already provide the answer. Did you tried to install latetest version of MbedStudio?

Another options:

  • switch to GCC but is very slow for compilation under MbedStudio
  • Keil Studio Cloud.

About AC6 I have no idea, you have to ask ARM.
