Support Question of the Week: Accelerating Bit Rate for Programming SPI Flash

Q: I am using the Aardvark host adapter to program 32MB SPI Flash. The write throughput is much slower than expected, 800KHz instead of 1KB/s. At this speed, it takes about two hours to program a Flash. How can I accelerate the bit rate?

A: Thanks for your question! The Aardvark adapter operates at bit rates up to 8MHz as an SPI master and...
