Hi I just started working on arm and I want to know Can we access or fetch a specific file( text,hex) from pendrive to arm controller to update controller firmware.
See the links I posted earlier.
I sounds like a school/college assignment - if so, seek support from your tutors / teachers / supervisors
What do you know already: - do you have any embedded 'C' programming experience? - do you have any basic electronics experience? - do you have any experience with, or understanding of, USB?
As noted above, STMicro has a specific example - so seek that out.
The Cortex-M is a very widely used architecture - there is plenty of material out there.
ST have a YouTube channel: www.youtube.com/.../UCjnmZw3h4XnpK3e5D2jvIGA including STM32 Online Training (OLT): www.youtube.com/.../playlists
ST's online learning: www.st.com/.../stm32-moocs.html
ST and their distributors frequently run real life training workshops/seminars - see what you can find locally.
They also do webinars: www.st.com/.../recorded-webinars.html
Thanks sir
