Open, Needs TriagePublic


This is a new request to integrate changes needed for improved portability to allow adding IAR Embedded Workbench as a supported tool chain for TF-M.

Event Timeline

Hi Thomas, I see you mention a failure with GNUARM 7.3.1 with some build config. Can you please provide instructions on how to reproduce the build failure? As you say the failure happens with the mainline as well, that shouldn't happen and I am not seeing the failure either. Would like to try to reproduce it here if it's a genuine issue.

Hi Thomas,

Regarding the change Antonio posted and for your own information I made similar changes here (
I have also posted a design change about implicit enumeration casting ( and will send patches for that soon as well :)

I got very useful information from this post and from this website too I always prefer this platform whenever I am stuck at any on anything currently I came here to take help with term papers and this post gives some good points to me.

This Workbench gives you a complete IDE with everything you need in one single view. I have used it for my work related project associated with the cv editing help, which ensures quality, reliability and efficiency in your embedded application.

IAR Embedded Workbench for Arm is an integrated development work environment and the included IAR C/C++ Compiler generates the fastest performing, although there are tons of projects like CV Makers which are based on IAR.

Wow, what a great post! I like it very much and cool that I recognized about 90% of them without hovering to see the Real DP-100 Exam Questions
