X-Port is not recognized by OSDK
Completed
Hi all.
I try to rotate X-Port without any load device.
I implemented the Linux sample code according to the OSDK tutorial (sample/platform/linux/main_async.cpp) and run in build/bin/payloads_async_sample
It works with H20 camera, but doesn't work with X-Port.
The difference in message is like this. As you can see, X-port is not recognized as payload[0].

What I have Done:
I thought there was a connection problem so I tried to bind with dji assistant2, but I couldn't bind.
When I push "bind" button in psdk menu, it says
"cannot get loading info." (in chinese, "无法获取负载信息".)
Payload status & Binding status are both disconnected.
Then I refer to this article,(https://sdk-forum.dji.net/hc/zh-cn/articles/900005780346)
boudrate is set to 460800,
X-Port is directly connected to M300 RTK,
PC is connected to M300 via OSDK Expansion Interface (I have verified that the osdk code runs correctly with this wiring.),
Thank you for your support!
-
thank you for your comments.
So you mean
1. Physically attach Xport to M300
2.press bind button on DJI Assistant2 Payload SDK interface
3.Run PSDK app
4.Run OSDK app
However, When I press bind button on DJI Assistant at step2. , Assystant says "cannot get loading info." regardless of whether I run PSDK or OSDK.
I tried swapping the order of these steps, but the result was the same.
I use only Laptop(LinuxOS), M300RTK, X-Port, and OSDK Expansion Interface.
-
For M300, OSDK function and PSDK function are independent, X-PORT is only related to PSDK development, no need to run OSDK app. Ensure that the payload status was connected when the PSDK app running.  -
Thank you. I checked the payload status when psdk app running. If I first attach xport like this order↓, then payload status is disconnected after running app.
payload status : DisconnectedBinding status : Unbound
1. Physically attach Xport to M300
2.Run PSDK app
3.press bind button on DJI Assistant2 Payload SDK interface
On the other hand, if I first run psdk app in this below order↓, then payload status was "Connected" between step 1&2, and it was chenged into "Disconnected" after I attach the X-port.So I cannot bind the payload.
1.Run PSDK app
2. Physically attach Xport to M300
3.press bind button on DJI Assistant2 Payload SDK interface
~~~ Work Flow ~~~
Run PSDK app via OSDK Expansion Interface.
↓
↓
attach X-Port while running PSDK app.
↓
One more unnatural point to report: When X-Port is attached, the x-port oscillates at high speed for a certain period of time and then goes into a free uncontrolled state.
Do you know whats wrong with binding x-port with running PSDK app?
-
1、Just connects the PSDK app to the X-PORT for binding, it is no need to run PSDK APP to the OSDK port for this binding operation.This is a hardware connections with skyport，just replace skyport to X-PORT.  2、There is no SN and "bind" button, please check your APPINFO on code file(dji_sdk_app_info.h), and account logged on DJI Assistant2 should be same as APPINFO of code settings.  3、This picture shows that PSDK APP runs on the OSDK port, please refer to the point 1. just run PSDK APP on PSDK port(X-PORT)  -
Thank you for your very kind help!
Then I have a question about device connection.
1. Where to connect RJ45 in your picture of device connection.This picture shows my understanding of device connection now↓.
USB TTL J10(UART serial)
PC(linux) ------------ PSDK Development Kit 2.0(adapter) ----------------- X-Port ------------ M300RTX
???? J40(Ethernet Port = RJ45)
2. In addition, when I use OSDK expansion board I defined LINUX_UART_DEV2 as /dev/ttyACM0 which connected to OSDK board in psdk/samples/sample_c/platform/linux/manifold2/hal/hal_uart.h ,so what should be defined as LINUX_UART_DEV2 ?
This article says LINUX_UART_DEV2 is for dual A USB Port, but there is no usb port in development kit 2.0.
(https://sdk-forum.dji.net/hc/zh-cn/articles/4408437830041)Actually when I run psdk app with above connection, the result is like this.
ubuntu@ubuntu:~/PSDK/build/bin$ sudo ./dji_sdk_demo_linux
[0.000][core]-[Info]-[DjiCore_Init:89) Payload SDK Version : V3.0.0-beta.0-build.1433
[1.736][adapter]-[Info]-[DjiAccessAdapter_Init:140) Try identify UART0 connection failed. Probably because SDK adapter or aircraft not finish init or UART connect error.
[3.511][adapter]-[Info]-[DjiAccessAdapter_Init:140) Try identify UART0 connection failed. Probably because SDK adapter or aircraft not finish init or UART connect error.
Thank you very much for taking the time to teach me again and again!!

1、This port was RJ45 port, connects this port to your device network port（e.g，pc Ethernet port）.  2、When the PSDK app runs on the PSDK port, LINUX_UART_DEV2 will not be used. just used for OSDK expansion port. 3、This error shows that the UART0 communication failed.   -
Thank you so much, I stopped using OSDK board and I'm succeed in identification of aircraft and mount position and error message has changed.
However, still I cannot bind PSDK.
Now my device connection between Raspberry Pi4 & PSDK toolkit & X-Port seems perfect and serial communication works well.
I checked the whole work flow in tutorial, especially dji_sdk_app_info.h, and create new app and make sure that the account is the same as the one I use for DJI Assistant2(enterprise series).
So I think there is no problem in dji_sdk_app_info.h, hal_uart.h, hal_network.h. (hal_uart.c can be problem because I modified it.)
Does anyone have the solution?Thank you for your help.
#What I have done:
### Modify hal_uart.c in order to LINUX_UART_DEV2 is not referenced.
1.line64 in hal_uart.c, I changed LINUX_UART_DEV2 -> LINUX_UART_DEV1
2.line250 in hal_uart.c, I changed isConnect = true; -> isConnect = false;
(https://sdk-forum.dji.net/hc/zh-cn/articles/4408437830041)###Firm ware Update on DJI assistant2(enterprise series)
