Compiler 5.06: CPU-Option Cortex-R4F vs Cortex-R5F

J K over 3 years ago

Hello,

with our ARM-Compiler-license (ARM-Compiler 5.06 Update 6, Build 750) we are not able the use the option Cortex-R5F (our MCU has this core inside, it's a TI Hercules TMS570LC4357 MCU).

So far, we use the option Cortex-R4F (license available for this).

Do we have any disadvantages when using Cortex-R4F instead of Cortex-R5F for the TMS570LC4357 Hercules MCU?

Thanks in advance,

Jens

Thank you for the confirmation that Cortex-R4 is a valid option for us. Multi-Processing is not a functionality of the RTOS we use. My colleagues are using iSYSTEM’s winIDEA and TI's Code Composer...
