Cortex-M, Cypress PSoC
embOS for Cortex M Cypress was developed for and with the Cypress PSoC development tool kit.
It can be used with the GNU compiler wich comes wit the development tools.
Alternatively, embOS Cortex M for KEIL MDK can also be used and run on the Cypress development board.
The user manual describes how to setup the sample workspace for usage with the GNU tools or KEIL MDK.
The trial version of embOS for Cypress Cortex M comes with libraries for the GNU compiler and additional libraries for the KEIL MDK.
