We are currently evaluating the reCamera (SG200x / CV1800B), focusing on remote agricultural IoT deployments for predictive production and early disease detection in berry crops. During our low-level testing, we have encountered two critical limitations regarding the sensor driver and power management that block its use for battery-powered remote nodes in the field.
- OV5647 5MP (2592x1944) Resolution blocked by precompiled driver & Missing Node-RED feature
Although the OV5647 hardware natively supports 5MP, the current Node-RED/sscma software caps the video and image capture at 1080p because it relies on the video stream. To bypass this, we wrote a custom C++ application using the official SDK (sscma-example-sg200x with sg2002_reCamera_0.2.1_emmc_sdk), configuring VI, VPSS, and JENC for a single 2592x1944 still picture.
However, startVideo() fails during VI initialization with the following output:
`pfn_cmos_set_image_mode(0) failed!
fail and return:[0xffffffff]
[app][err][app_ipcam_Vi_Init 447]app_ipcam_Vi_Sensor_Start failed with 0xffffffff`
Based on our debugging, it appears the precompiled sensor object (sns_ov5647.o) lacks the I2C register configuration tables for the 2592x1944 mode.
Request: First, could you please update the SDK / sensor library to include the 5MP profile for the OV5647? Second, and most importantly, the ideal solution would be the addition of a dedicated Node-RED node in your platform specifically designed to trigger full-resolution (5MP) still image captures, operating independently from the 1080p video stream limitation. High resolution is critical for our computer vision tasks in agronomy.
- Firmware-level Deep Sleep / RTC Wake-up for Battery Operation
For our field operations, we need to take scheduled photos (e.g., 4 times a day) using battery-powered nodes. Currently, keeping the Linux OS fully awake drains the battery in a matter of hours.
Request: Does the SG200x PMU support any form of Deep Sleep (Suspend to RAM) combined with RTC wake-up alarms? We are strictly looking for a native, firmware-level solution to put the device into a low-power state and wake it up internally, without relying on external hardware timers. If this capability is not currently implemented in the reCamera OS, could it be added in a future firmware update?
Thank you for your support and for this great hardware.
