Pixhawk 2.4.8 firmware 1.14.0beta

Hi. In jmavsim, i’m using 1.14.0beta firmware. Is it possible to upload this firmware to my real pixhawk 2.4.8. If it is possible, where can i download this firmware?
By the way, if it is impossible, which firmware version should i upload?
Thanks a lot

You should be able to build and flash it yourself by doing make px4_fmu-v2_default upload or make px4_fmu-v3_default.

(See Loading Firmware | PX4 User Guide if you’re confused regarding v2 and v3.)
