Significant delay between SPI Commands using SPIDEV

Hi all,

I’ve been working with an AI64 and have noticed that there is a significant delay between sending successive SPI commands to a peripheral device. Is there a significant overhead with the spidev driver that could be causing this, or is there another explanation?

With direct hardware interaction from a R5 core I was getting around 3 microsecond separation iirc. Maybe you could try that from Linux
