Problem with PlayUAV setup


Hey, I got the PlayUAV but am having trouble setting it up. First, after powering it up there is no video output either with PX4 telemetry or without. This is in self-sync mode with no camera attached, I am just bench testing. Second, when connecting to the config tool, it cannot update the firmware and times out while connecting. The bootloader doesn't enumerate any USB device but firmware does enumerate PX4FMU device. The config tool also won't connect to the PlayUAV OSD, as it says the firmware is too old, and I can't find any older versions of the config tool online.

It doesn't look like there is a ROM boot loader jump pin anywhere, so I can only flash through SWD? Even if this is the case, I can't seem to find firmware/bootloader images anywhere to flash with ST-Link, and I'm not set up to compile - a few months ago I saw some Keil projects in the firmware folder, which would be easy to use, but I don't see those anymore.

Thanks :)

Hi,

About the board wired instruction, please refer to the wiki-wired. If you wire the video out signal and video out GND to your screen with the board power-on, you will get the OSD information(the board has BL, firmware and settings by factory default).

For the COM port issue, I suggest you change the USB cable and try again. You can upload the firmware online or use customized firmware in File menu.

At wiki-wired, there is a debug SWD which you can use with ST-LINK. You can use the bootloader directly.

Both bootloader and firmware can be built with arm-gcc. Here is the build instruction

Best,

Hi, thanks for the fast reply, I think the issue was the MAX being undervolted, as the osd works when the battery is plugged in to pixhawk, and it works with the pixhawk disconnected.

For the OSD not being able to flash, I'm not sure, but it's working now, with the same usb cable.

Hi, glad to see it works. The driver supply voltage of MAX chip is 4.75~5.25. The USB voltage from PC especially notebook is often under voltage. I suggest that you use a USB HUB with power supply.

Best,
Tom
