Can't connect Nano 33 BLE (not sense)

I followed instructions on Arduino website on how to connect nano 33 ble to openmv. After installing latest firmware (v4.3.1) OpenMV doesn’t see my board. Tells “No OpenMV Cams found”. OpenMV version 2.9.2
If I manually choose Nano 33 ble board from a list, “No BOSSAC settings for the selected device” message comes out.

Bi, this is an issue related to installing the bootloader with the Arduino IDE to enable openmv on the Arduino Nano BLE. When done right the process works.

Sorry, just did one more time, missed couple steps in arduino ide. It seems to work now
