Dear, I wonder if there is a gnu compiler distribution for adsp-cm4xx.
You can use the actual version - as the core is either a Cortex M4 or a combination of M4 + M0 - these are fully supported by GCC. There is i.e. a ADSP-CM408F example available with emIDE for download @ http://www.emide.org/files/samples/Analog_ADSP-CM408F_EZ-Kit_Blinky.zip
We can confirm that, at time of writing, ADI does not provide any GCC support for ADSP-CM4xx processors.
