Installing the toolchain on pixhawk 4

Hi Guys,

I am trying to flash on pixhawk 4 but the process doesn’t complete. I get the following on the terminal:

Attempting reboot on /dev/tty.usbmodem1 with baudrate=57600…
If the board does not respond, unplug and re-plug the USB connector.

Found board id: 50,0 bootloader version: 5 on /dev/tty.usbmodem1
sn: 0047002e3038511534323338
chip: 10016451
family: STM32F7[6|7]x
revision: Z
flash: 2064384 bytes
Windowed mode: False

Erase : [====================] 100.0%
Program: [====================] 100.0%
Verify : [====================] 100.0%
Rebooting. Elapsed Time 23.426

I don’t know why it doesn’t reboot the pixhawk. I use the following command to upload the firmware on pixhawk 4: make px4fmu-v5_default upload

Any pointers will be appreciated.
