New boards as of 03/05/2024 have the bootloader already installed. You do not need to program the bootloader in that case
If you will be using PX4 software with the MR-VMU-RT1176 board then you will need to first program the bootloader if not already installed.
The abbreviated instructions are as follows:
Connect the holybro pixhawk debug adapter, with SEGGER debug probe connected, to Pixhawk 6X-RT
Power the Pixhawk 6X-RT either via USB or POWERx connector.
Launch JlinkExe tool from Segger
Type connect
Select SWD and target is MIMXRT1176XXXA_M7
Type reset and halt
Type loadbin /path/to/firmware/px4_fmu-v6xrt_bootloader.bin 0x30000000
If you wish to flash PX4 at this time, it can be done with the additional command:
Type loadbin /path/to/firmware/px4_fmu-v6xrt_default.bin 0x30020000
To complete the process:
type reset and go
Some additional debuggers will be available in the future. Currently this is our reference setup
The Debug adapter DCD-LZ from hovergames does not currently have the correct adapter the cable to plug into the FMURT1176. This will be updated in the future. Technically you could make your own.
