|

- VAR: Cortex-M VTOR initialization is now performed in startup files and
|
||||
no more in port initialization.
|
||||
- VAR: Changed GCC asm files extension from .s to .S because conventions.
|
||||
- VAR: Updated CMSIS to version 4.50, it still contains the same errors
|
||||
found in 4.30, fixes applied.
