Cortex-M, IAR

embOS for Cortex M and IAR workbench V6 was developed for and with IAR's compiler version V6.10 and can be used with newer versions also.
embOS for Cortex M is fully CMSIS compliant.
embOS for Cortex M and the older IAR workbench V5 (available on request) was developed for and with IAR's compiler version V5.41 but can be used with other IAR V5.x compiler / workbench versions also.
embOS supports all memory models offered by the IAR compiler. It comes with easy to use start projects for IAR's embedded workbench. Initilization code for different Cortex M0, Cortex-M1, Cortex-M3, Cortex-M4, Cortex-M4F and Cortex-M7 starter boards is included. Software development with C-SPY simulator or C-SPY debugger with JTAG tools like J-Link is possible.
