Приветствую. Не могу получить софт у поставщика, кто имел опыт работы с этим камнем? Хочу попробовать в качестве audio DSP

The i.MX RT600 is a crossover MCU family optimized for 32-bit immersive audio playback and voice user interface applications combining a high-performance Cadence Tensilica HiFi 4 audio DSP core with a next-generation Cortex-M33 core. The i.MX RT600 family of crossover MCUs is designed to unlock the potential of voice-assisted end nodes with a secure, power-optimized embedded processor.

The i.MX RT600 family provides up to 4.5MB of on-chip SRAM and several high-bandwidth interfaces to access off-chip flash, including an Octal/Quad SPI interface with an on-the-fly decryption engine.

Cadence Xtensa HiFi4 DSP

Так же и в составе Allwinner T113-S3 есть. Где-то должен существовать компилятор С для этого процессора от Cadence - XCC

Есть документ по архитектуре HiFi 3- hifi_3_dsp.pdf

Нашел софткит с примерами: https://github.com/nxp-mcuxpresso/mcux-sdk-examples/tree/main/evkmimxrt685

Кстати получилось собрать новую среду разработки тут(ВПН): https://mcuxpresso.nxp.com/en/builder?hw=EVK-MIMXRT685

Платы Mimxrt685-EVK есть на авито!)
