Hi All, I am new to Freertos. I need some quick help here. We are working on a starter kit(GR5515) provided by GOODIX. This kit has GR5515 MCU in it. We want to develop an application on top of Freertos. For this I need a freertos port which can run on GR5515 MCU (Cortex M4F core) & arm provided compiler version 5.06. I searched the supported devices section of Freertos page and understood that there is no supported freertos port for GR5515 MCU & arm compiler. Can someone help me on how to get the required port for above need. ---

You mean the same port ca be used for any MCU which has cortex M4 core & irrespective of compiler we use? By the way core is cortex M4F. ---

> [@Raghu](#): > > You mean the same port ca be used for any MCU which has cortex M4 core & irrespective of compiler we use? Yes, but NOT irrespective of the compiler. Since you mentioned that you want to use ARM GCC, I suggested to use GCC port. The specific port you use is a combination of compiler (GCC in your case) and architecture (Cortex-M4 in your case). > [@Raghu](#): > > By the way core is cortex M4F. That is fine. ---

Thank you for your quick responses. Compiler in use is “ARM Compiler V5.06” and not ARM GCC. Can you send me the link to port for above combination (Cortex M4F + ARM compiler V5.06). ---
