Generation 2 and generation 3 technology stacks share the same firmware but with different VIDs/PIDs.
Using Cypress firmware update tools with generation 2 modules does require a recovery boot, in order to force enumeration as Cypress USB Generic Driver.
On the other side, using Cypress firmware update tools with generation 3 modules may not require a recovery boot (if a Generation 3 reference firmware is running on USB FX2 microcontroller). This is possible because the original Cypress USB Generic Driver (in case of a recovery boot) and the Trenz Electronic USB FX2 device driver ( in case of a regular boot) are both Cypress driver. Trenz Electronic USB FX2 driver derives from the original Cypress USB Generic Driver.
The firmware update procedure is similar for both generations. The following table summarizes the main differences. See also this video play lists for Cypress recovery boot and this page for OpenFutNet recovery boot.
