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 [...]

Support Question of the Week: Fully Erase Flash Memory before Re-programming Device
Q: I am re-programming 16MB into 16MB flash memory, which needs to be erased before re-programming. My question – does Flash Center automatically do a full chip erase before re-programming a flash memory device, or is there a setting I need to apply? I’m asking because when I used 120KB images on the device, [...]
