This module introduces Tarmac trace from Fast Models, and uses that to walk through everything a Cortex-M3 device would do if used with CMSIS code from Reset to the main() function, to triggering an interrupt using the NVIC. Although the module is related to a Cortex-M3 device, the details presented also apply to any Armv7-M / Armv8-M device, acting as a recap of all the content covered in this M-profile course.

Frequently asked questions

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
