Our customer use GX3 for their production board.
Is it possible to redistribute Windows Drivers published on the Cypress's website for end users?
Or do the end users need to download it from the website themselves?
You can redistribute, but it is better to send a GX3 link to customer rather than downloading the driver and sending.
Because there can be periodically updated and if the customer download from Cypress website, the customer will be able to always get the latest revision driver.
