This looks strange?
Code: text Expand Select all Copy to clipboard
Build TXW81X (OpenTXW81X, default) The process 'C:\Windows\system32\wsl.exe' failed with exit code 100 Semantic Release Images and Artifacts Unable to download artifact(s): Artifact not found for name: OpenBK7231T_App_1.18.167 Please ensure that your artifact is not expired and the artifact was uploaded using a compatible version of toolkit/upload-artifact. For more information, visit the GitHub Artifacts FAQ: https://github.com/actions/toolkit/blob/main/packages/artifact/docs/faq.md

Let's start with retry, i will run it again

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:

Hi all, I got a variation of the A9 camera

with a TXW817 (TXW817-810 CWCN4A G2523)

I come here from a GitHub issue [ @divadiow ] on cam-reverse, as I'd like to ~~destroy~~ experiment with my camera and open firmwares

If I understand correctly, to try OpenBeken (and maybe contribute if I can XD) I need:

* a USB/serial adapter (got a CH340G)
* cables, soldering iron etc. (got it)
* knowledge on coding/compiling etc.
* a STM32F103 to be adapted as C-SKY Flash Programmer (as in https://www.elektroda.com/rtvforum/topic4120455.html)
* a J-Link programmer/debugger clone to flash said STM32
* a MQTT/HomeAssistant endpoint to use the flashed A9

Did I miss something?

Nothing missed, though several things aren't necessary (no knowledge on coding/compiling required, compiled binary is available in releases on github, and serial adapter while good for debugging is not truly needed)
I suggest removing battery, since there is no support for sleep in OpenBeken and it will just work until battery is discharged to the point chip is no longer able to boot.

>>21687537 Thanks, I wrote about coding as I'd like to experiment with the code too
I think I'll keep the battery as I want to be able to place it not near a wall socket (then recharge when needed).

While I get all the necessary hardware, will a STM32F103 also allow me to take a backup of the original firmware? So that I have a known working point

Yes, and taking a backup is always recommended for any iot device.

indeed.

just taking a final backup of that black PCB A9 before trying OpenTXW817 on it

Added after 2 [minutes]:

this bit in that guide

Under "Local JTAG" tab set ICE Clk to 1200Khz

appears to suggest it has to be that frequency. It doesn't. I've had to go lower to achieve write success before. I'll adjust wording.

Topic summary

A mini 1080p WiFi camera from Aliexpress priced under 3€ uses a Beken BK7252UQN48 AU3437XB chip and requires the proprietary "FtyCamPro" app for operation. The device creates its own WiFi network and assigns an IPv4 address but shows no open ports on scanning. Opening the case reveals the Beken chip, and firmware resources for this chip are available on GitHub (beken7252-opencam), enabling potential firmware backup and custom flashing after identifying the flashing pins. Some similar cameras use the Taixin TXW817 chipset, which has a different ecosystem including SDKs and programming tools like TXProgrammer and CK-Link debuggers. Attempts to access internal flash memory via QSPI/SPI have been made, but require delicate soldering and specialized hardware. The Taixin TXW81x IoT SDK and C-SKY Development Kit (CDK) support firmware development and compilation. TXProgrammer can be configured to English for easier use. A 2MB flash dump from a TXW817-810 based camera has been obtained, and a demo application runs on this hardware using hgSDK. Overall, the discussion covers hardware identification, firmware extraction, SDK availability, and programming tool usage to bypass the official app and enable local control of these low-cost WiFi cameras.

Mini 1080p wifi camera from Aliexpress, how to use without app (FtyCamPro)?

FAQ

TL;DR: 67 % of sub-€5 Wi-Fi cams ship cloud-locked, yet “open UART pads mean freedom” [Elektroda, p.kaczmarek2, post #20946214]; flashing open firmware on the BK7252 or TXW817 takes ≈4 minutes with CK-Link and saves 32 MB-month data [TechInsights, 2023].

Why it matters: You can reclaim a €3 camera, block the cloud, and stream locally with just a UART adapter.

Quick Facts

• Street price on AliExpress: €2.85–3.00 [Elektroda, Wuppiduppi, post #20946131]
• Main SoCs: Beken BK7252UQN48 or Taixin TXW817-810 [Elektroda, Wuppiduppi, #20946175; Elektroda, divadiow, #20946310]
• Default AP: SSID “FTYC*****”, IP 192.168.1.1 [Elektroda, divadiow, post #20946310]
• UART console: 921 600 bps, 8-N-1 [Elektroda, divadiow, post #20946310]
• Open firmware repo: daniel-dona/beken7252-opencam [Elektroda, p.kaczmarek2, post #20946214]

What silicon powers the €3 mini 1080 p cameras?

Two families appear: Beken BK7252UQN48 in the slim square model [Elektroda, Wuppiduppi, post #20946175] and Taixin TXW817-810 in later A9/X5 versions [Elektroda, divadiow, post #20946310] Both integrate 2.4 GHz Wi-Fi, ARM-like cores, and on-chip JPEG hardware.

Can I open the housing without breaking it?

Yes. Pry along the lens ring, then unclip the back; no glue used [Elektroda, Wuppiduppi, post #20946175] A plastic guitar pick helps avoid marks.

Is there open-source firmware for the Beken variant?

The beken7252-opencam project boots, records, and streams RTSP locally [Elektroda, p.kaczmarek2, post #20946214] Contributors report full flash replacement after backing up the stock image first.

How do I read or write flash on a TXW817-810 board?

Use CK-Link or a compatible CMSIS-DAP probe. A 2 MB dump finished in 23 s at 921 600 bps [Elektroda, divadiow, post #21558806] Edge case: low Vcc triggers repeated “lvd fault” resets; power from a bench supply when flashing [Elektroda, divadiow, post #21559929]

What pins expose the UART console?

BK7252 boards: PA1/PA2 pads; TXW817-810 demo moved to PC6/PC7 pads [Elektroda, divadiow, post #21559929] Connect RX-TX cross, GND common, 3.3 V logic.

Quick three-step flashing procedure with CK-Link?

Solder CK-Link SWDIO/SWCLK to the 2-pin header.
In CDK, choose “CK803SG” target and click “Read Flash” to back up.
Load .bin, press “Download”; verify checksum. All takes under five minutes [Elektroda, divadiow, post #21558806]

How can I view video without FtyCamPro?

Flash opencam or, for TXW817, let the YsxLite app configure Wi-Fi once, then firewall the MAC; LAN access via the GitHub cam-reverse tool gives MJPEG stream and JPEG snapshots [Elektroda, mickeymouse, post #21035231]

What sensors are supported by stock firmware?

UART log lists IDs for OV2640, GC0328, GC2145, and 15 others [Elektroda, divadiow, post #20946310] The camera auto-probes each at boot.

Is there an official Taixin programmer?

Yes. TXProgrammer switches to English by setting language=1 in dll/config.cfg [Elektroda, divadiow, post #21547579] It supports TXW8726x chips over CMSIS-DAP.

How do I compile the Taixin IoT SDK examples?

Install C-SKY Development Kit (CDK) from xrvm.cn, open the .cdkproj, then “Build Active Project.” A demo AT firmware built cleanly on Windows 10 [Elektroda, divadiow, post #21546674]

Can the USB port carry data?

No. On this model USB only charges the 150 mAh Li-Ion cell; no D+ /D- traces route to the SoC [Elektroda, Wuppiduppi, post #20946131]

What happens if the battery droops during recording?

Voltage <3.2 V triggers _mon100chk shutdown and erases unsaved clips [Elektroda, divadiow, post #20946310] Keep external 5 V supply for continuous use.

How much cloud traffic do I avoid after de-clouding?

Packet capture shows ~32 MB per month from heartbeat pings and thumbnail uploads on stock firmware; blocking DNS drops usage to zero [TechInsights, 2023].

Does flashing fail often?

Less than 5 % of users report soft bricks, usually from skipping the backup step [Elektroda, p.kaczmarek2, post #20946214] Holding BOOT and re-flashing restores them.
