Info

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), but only an update boot. 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.
