Dear all,
I am currently developing a baseboard to integrate an FMUv6X. I have thoroughly reviewed the Pixhawk Standards documentation (available at GitHub - pixhawk/Pixhawk-Standards: Pixhawk Standards · GitHub), but I must admit that one aspect remains unclear to me.
I am unable to determine whether the baseboard should include the FMU’s coprocessor (an STM32F103) or if it is already embedded within the FMUv6X itself. Upon examining the M1 to M8 outputs of the standard baseboard, it appears that these signals originate from IO_CH1 to IO_CH8 (and thus from the coprocessor). However, the only connections between the FMUv6X and the baseboard are the X1 and X2 connectors, neither of which includes an IO_CH pin. Connector X1 does feature FMU_CH1 to FMU_CH8 pins, which correspond to AUX1 to AUX8 outputs, but these are not relevant to my project.
Therefore, I assume that the baseboard must indeed integrate the coprocessor, controlled by the STM32H7 via the UART6 bus, as described in the documentation (DS-012 Pixhawk Autopilot v6X Standard). However, I have been unable to confirm this hypothesis despite reviewing numerous websites and documentation.
Could someone with sufficient knowledge of the V6X environment either confirm my assumption or clarify where I might be mistaken?
Thank you in advance for your assistance ^^.
