I updated ASF from 3.34 to 3.40 when updating AS to 7.0.1931. I was surprised to see that there are a some changes in the E70 header files (after not seen any changes for years...).
Second I noticed that there is a new compiler symbol "__SAME70Q21B__" in the project settings. I compared the project files and found that this was previously "__SAME70Q21__".
Now I found in the release note of ASF 3.40 a small "note":
Note: SAME70 Xplained Pro and Examples are moved from Rev A silicon to Rev B. Do Not upgrade to this ASF release if you are want to use the SAME70 Xplained Pro and Examples with silicon Rev A
Is there any silicon revision B coming which is not compatible with revision A ?
What is the difference between A and B and when is it available ?
How can I make sure that our application still runs on our home brew E70 HW based on silicon rev A after doing an ASF upgrade ?
