J3는 3번 핀과 5번 핀(GPIO_23 RXD, GPIO_22 TXD)을 통해 UART7만 제공하며, 해당 장치는 /dev/ttyHS1로 열거됩니다. UART13은 J3가 아닌 고속 B2B 포트인 J5에 있습니다. J3 및 J5의 전체 핀 구성은 다음 링크를 참조 하십시오.

-> Are any additional configuration steps required to enable UART7 on J3 and UART13 on J5, or are they already enabled by default?

Hardware: (board / drone / SKU, serial # if you have it): voxl2

Software version: (paste the output of voxl-version)

Configuration / services: (paste the output of voxl-inspect-services)

What I am trying to do:

1. When the M0155 board is connected to VOXL 2, is GPIO 109 enabled to output a 30 Hz sync signal, as it is with the M0173 board?
2. If we connect IR and EO cameras to the J6 and J7 connectors on VOXL 2 through the M0155 board, will the cameras be synchronized automatically, or are software configuration changes required?

What actually happens: (error messages, behavior)

Steps to reproduce:

Logs / pictures: (attach files; PX4 logs -> https://logs.px4.io)

Hardware: (board / drone / SKU, serial # if you have it): M0041, M0173

Software version: (paste the output of voxl-version

Configuration / services: (paste the output of voxl-inspect-services)

What I am trying to do: :
1. Current Sensor on the M0041 Board
Could you provide the part number of the current sensor used on the M0041 board? Also, what I2C slave address is configured for this sensor on the board?
2. Connector Pinout on the M0173 Board
Could you provide the signal name for each pin of the M0173 board connector highlighted in the image below? We would specifically like to know which pins carry the SPI signals.

What I am trying to do:
1. IMX412 Camera Frame Rate Configuration

• list itemCould you confirm whether the IMX412 camera’s frame rate can be set to 8.6 fps to match the operating frequency of our IR camera (Lenton)?

• list itemIf this requires modifications to the kernel or camera driver, could you provide instructions for building and flashing the modified software?

• list itemIs it possible to change the frame rate through software configuration after boot without modifying the kernel?

2. UART Configuration on the J3 Connector

• list itemCould you explain how to configure and enable the UART7 and UART13 pins on the VOXL 2 J3 connector for communication with an STM32?

3. Camera FSync Configuration on the J3 Connector

• list itemCould you confirm the GPIO assignment and control mechanism for outputting an FSync (Frame Sync) signal to a camera through the J3 connector?

• list itemCould you provide instructions for enabling the FSync signal, configuring its period, and applying the settings?

4. Clarification Regarding the Boot Mode Switches on the M0062 Board

Our understanding is as follows:

• list itemFastboot is a bootloader mode used to install or update system images.

• list itemEDL is a low-level recovery mode used when a boot failure prevents access to Fastboot.

The VOXL 2 includes Fastboot and EDL switches. We believe access to these switches may be necessary during development and operation in case recovery is required. Please refer to the image below for the connections between the VOXL 2 and the M0062 board.

However, based on the M0062 board block diagram, the boot mode switches on the M0062 board appear to be unused. Could you confirm whether these switches are actually used and, if so, under what circumstances?
