Recently I got Pixhawk5x and tried to flash it with customized fmu-v5x firmware based on v1.12.3.
However, whenever I re-connect the USB cable, Pixhawk5x doesn’t go to firmware upgrade mode and it just boots, then flashing fails. It shows this error messages.
Error: Sync: Send Command: Invalid sync response: 0xfe 0x3c Upgrade cancelled
I haven’t experienced this issue on Pixhawk4 or older Pixhawks with PX4 v1.11.2.
I am using MacOS Catalina 10.15.7.
- using latest stable QGC
- using differnt usb-c cable
- re-installing FTDI driver
- re-installing px4 common tools using toolchain
- rebooting the computer
but didn’t work.
I can flash the firmware on Windows after installing the latest QGC, so it seems to be a problem on MacOS.
Do you have any advice on this issue?
