Multiplatform BK7231 BK7238 Beken Flash Tool - Web, Android, Windows - First Prototype

p.kaczmarek2 1629 29

TL;DR

EasyGUIFlashTool is an early multiplatform IoT flasher for Beken BK7231/BK7238 chips, with shared Web, Android, and Windows workflows.
The web build uses Web Serial and WebUSB, runs on GitHub Pages or locally, and lets users choose firmware, set flashing parameters, and watch progress.
The tool has tested communication speeds up to 1,500,000 baud and includes a built-in firmware downloader plus command-line working mode.
The web version may fail to auto-reset devices because DTR/RTS pins do not always work in Chrome, so localhost deployment is recommended.

Here I will present a multiplatform IoT flashing solution – an early prototype of EasyGUIFlashTool. The goal of this project is to provide a simple, consistent, and user-friendly flashing experience across multiple platforms, without the need for vendor-specific tools or complex setup procedures. The same workflow and GUI concept are shared between Web, Android, and Windows builds. The current version of the tool is able to flash Beken chips and has built-in firmware downloader and command line working mode.

Previous version
For generic information, see previous (Windows) project repository:
https://github.com/openshwprojects/BK7231GUIFlashTool

Web Presentation (GitHub Pages & Locally Deployed)
The web version is based on modern browser APIs (Web Serial / WebUSB) and can be hosted either on GitHub Pages or run locally without any backend services.
It allows selecting firmware files, configuring flashing parameters, and monitoring flashing progress directly from the browser.

Tested communication speed up to 1 500 000 baud on supported devices.

There is a single known issue with web version - DTR/RTS pins used for automatic RESET may not work in some cases, it seems to be caused by Chrome limitation. For best experience, run the flasher locally, on localhost.

Android Presentation
The Android version is intended mainly for field work and quick device recovery.
It requires connecting the target device using either:
- USB-C to USB-C cable, or
- USB OTG adapter

The application provides the same flashing logic as the web version, adapted to mobile UI constraints, and does not require root access.
All flashing operations are performed locally on the device.

Windows Presentation
The Windows version runs as stand-alone application, it supports also a command line mode, same as main flasher.

Still, currently it should be used only for testing, because on Windows we have a main mature version of our flasher:
https://github.com/openshwprojects/BK7231GUIFlashTool

How to get binaries
Get Android .apk and Windows .exe (and soon probably Linux and Mac builds, if possible) here, in releases tab:
https://github.com/openshwprojects/EasyGUIFlashTool/releases
Source code:
https://github.com/openshwprojects/EasyGUIFlashTool
Online Web version:
https://openshwprojects.github.io/EasyGUIFlashTool/

Summary
This is an early prototype intended to validate the core idea and cross-platform feasibility.
The UI provides only basic functionality, flashing backend supports only Beken, more is to come soon.
Please check how good it works for you and let me know!
With enough positive feedback, more chips will be ported soon!

this is exciting. I spent 5 mins on a quick Ubuntu test last night but BK7231N kept failing CRC after write. I see some newer builds have appeared since my attempt though, so will check again

I tested only BK7238 so it's possible that we have logical error on BK7231N, if CRC check fails. You'd need to compare with old flasher.

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:

Wow, 1500000 worked? Well, maybe indeed it's a promising tool! I had a hard time getting it to work stable. At first I was afraid, it's too unstable for any release.

I didn't test on anything other than BK7238, so your testing is very valuable, I'll try to fix it so it follows our main C# flasher convention.

BK7238 on 1500000 baud without manual CEN reset started reading just fine, but halted at something like 0x1A0000.
Stop didn't do anything, i've had to wait until it stopped by itself.
Second try at 1500000 failed too (0x1CA000)
Third at 921600 succeeded.

BK7231N at 1500000 is fine

Combo box is annoying, it should behave like a windows one (entries should be below combo box itself). Or is it intended?

Not intended, and any hints like that are welcome, thanks. It's early prototype, I weren't sure about usability so I didn't focus on UI.

Question: is autoreset working for you guys here:
https://openshwprojects.github.io/EasyGUIFlashTool/
I mean DTR/RTS.

Autoreset worked for both 7238 at 921600/1500000 and N at 1500000.
Didn't test for T, i manually reset it.
7238 - NiceMCU, N - T2 board.

Hi, i try testing tool online with chrome browser...
some questions :
3,3 v from usb-UART is it sufficient for wifi board ?
is this the only solution to put CEN on ground, ? because i read that we must put it very quickly (0,25s) ! and that never works for me...
thanks for this tool !

From which USB to UART board? Usually not, unless there is AMS1117-3.3V on your board.

I've pushed experimental BL602 port, seems buggy, sometimes works, sometimes not.

backup and flash @ 1500000 - only does backup, doesn't start flash. took a few rsts to catch

T write only - gets caught on same bl protection as erase

There is no AMS1117-3.3 on board, and I can't see any other LDO. This probably won't be enough.

I mean, this requirement is general - it does not depend on used flash software. You just need a good power supply to do it.

Alternatively, if there is AMS1117-3.3 on your smart device board, you could feed 5V from USB to the input of this LDO, to get 3.3V for WiFi module. This can also work.

Thank you for testing! I was sure that web is more stable than windows build of easy flasher, but now I am confused.... hmm, this needs more testing.

In order to configure initial relay state (open, closed or memory) you need to go to "Configure startup" section in options.

This is actually impressive. Seems to work better than esptool.js for flashing ESP32 - though it doesn't allow to specify the flashing offset, which is a major disadvantage. I would love to see that option added.

Side note - I'm testing on Firefox, using the WebSerial for Firefox extension, and it works surprisingly well - so no more Chromium needed to use it.
(disclaimer: I'm the author of that extension.)

Unsure if it's just a Firefox issue, but drag and drop doesn't work at all - dropping a file just leaves it on the orange "Drop file here" box, with the following error in the console:
Code: text Expand Select all Copy to clipboard

Multiplatform BK7231 BK7238 Beken Flash Tool - Web, Android, Windows - First Prototype

FAQ

TL;DR: Early prototype EasyGUIFlashTool flashes Beken BK723x across Web, Android, and Windows, tested to 1,500,000 baud; “the same workflow and GUI concept are shared between builds.” [Elektroda, p.kaczmarek2, post #21842603]

Why it matters: It gives makers and field technicians one consistent, no-vendor flasher for recovery and updates across devices and platforms.

Quick Facts

Cross‑platform: Web (Web Serial/WebUSB), Android, and Windows with shared GUI and logic. [Elektroda, p.kaczmarek2, post #21842603]
Tested communication speed: up to 1,500,000 baud on supported devices. [Elektroda, p.kaczmarek2, post #21842603]
Known web caveat: DTR/RTS auto‑reset may fail in Chrome; run locally for best results. [Elektroda, p.kaczmarek2, post #21842603]
Android needs USB‑C to USB‑C or USB OTG; no root required, all flashing local. [Elektroda, p.kaczmarek2, post #21842603]
Source and releases: GitHub repo, Releases tab, plus online Web build. [Elektroda, p.kaczmarek2, post #21842603]

What is EasyGUIFlashTool and who is it for?

EasyGUIFlashTool is a cross‑platform IoT flasher with one workflow across Web, Android, and Windows. It targets makers, repair techs, and developers who need simple, vendor‑agnostic flashing and recovery for Beken‑based devices. It is an early prototype focused on validating the UI and core back end. The tool emphasizes minimal setup, built‑in firmware download, and clear progress feedback. The author invites testing and feedback to guide next steps and chip support. [Elektroda, p.kaczmarek2, post #21842603]

Which chips does this prototype support today?

The current build supports Beken chips, including the BK723x family highlighted in the thread title. The author states the flashing back end supports only Beken for now. With enough positive feedback, additional chips will follow. This staged approach keeps the tool stable while expanding hardware coverage. “More is to come soon.” [Elektroda, p.kaczmarek2, post #21842603]

How do I flash a BK7231/BK7238 from my browser?

Open the Web build using a browser that supports Web Serial/WebUSB.
Connect your target device, select firmware, and set flashing parameters.
Start flashing and monitor progress in the UI. If auto reset via DTR/RTS fails in Chrome, run the flasher locally for best results. The web app requires no backend and works from GitHub Pages or local hosting. [Elektroda, p.kaczmarek2, post #21842603]

What cables or adapters do I need on Android?

Use either a USB‑C to USB‑C cable or a USB OTG adapter, depending on your phone and target device. The Android app mirrors the web logic but adapts controls for mobile. It performs all operations locally, so you do not need root or cloud access. This setup is ideal for field recovery and on‑site flashing without a laptop. [Elektroda, p.kaczmarek2, post #21842603]

Does the Android app require root or an internet connection?

No. The Android version does not require root, and all flashing operations happen locally on the device. This supports secure, offline workflows during field service or lab use. You only need the APK, the firmware files, and the correct cable or OTG adapter. The UI matches the desktop and web concepts for quick ramp‑up. [Elektroda, p.kaczmarek2, post #21842603]

Is there a command‑line mode for automation?

Yes. The Windows version supports a command‑line mode, matching the main flasher’s behavior. This helps integrate flashing into scripts or CI steps. It complements the GUI for batch operations or recovery pipelines. As this is a prototype, treat it as a test bed while the mature Windows flasher remains primary. [Elektroda, p.kaczmarek2, post #21842603]

What baud rates does EasyGUIFlashTool handle?

Communication has been tested up to 1,500,000 baud on supported devices. That headroom speeds up flashing and reduces field time. Actual stable rates depend on your adapter, wiring, and device state. Always verify integrity after flashing when pushing high data rates. Fast is good, but reliability is critical in production. [Elektroda, p.kaczmarek2, post #21842603]

Where can I download the binaries and source?

Grab Android APKs and Windows EXEs from the GitHub Releases tab. The source code is on the same repository for audits and contributions. A hosted Web version is available, and you can run it locally without a backend. Linux and macOS builds are planned, subject to feasibility. [Elektroda, p.kaczmarek2, post #21842603]

What’s the known edge case with the Web flasher?

Auto reset using DTR/RTS can fail in some cases due to a Chrome limitation. The author recommends running the flasher locally on localhost for best behavior. If you see inconsistent resets, reconnect and retry after switching to local hosting. This is a prototype caveat, and improvements are expected. [Elektroda, p.kaczmarek2, post #21842603]

Is the Windows build production‑ready?

Use the Windows build for testing today. For production work on Windows, the author points to the mature BK7231GUIFlashTool. The EasyGUIFlashTool Windows app mirrors the cross‑platform UI and supports CLI, but it remains in early stages. Keep critical workflows on the stable Windows flasher for now. [Elektroda, p.kaczmarek2, post #21842603]

Does the tool include a firmware downloader?

Yes. The prototype includes a built‑in firmware downloader to reduce setup friction. This speeds first‑time flashing and helps during device recovery. You still control which file to flash and the parameters. The unified UI keeps the process consistent across platforms. [Elektroda, p.kaczmarek2, post #21842603]

What do Web Serial and WebUSB mean here?

They are modern browser APIs that let the web app talk to connected devices over serial and USB. The tool uses them to list ports, open connections, and stream flashing data within the browser. This removes native drivers and backend servers from the flow. Use a compatible Chromium‑based browser for best results. [Elektroda, p.kaczmarek2, post #21842603]

What are DTR and RTS in this context?

DTR and RTS are control lines often used to trigger automatic reset or boot modes on target MCUs. The web app toggles them to streamline entry into flashing mode. A Chrome limitation can interfere with this automation. Running on localhost improves reliability during the reset sequence. [Elektroda, p.kaczmarek2, post #21842603]

Can I use this tool entirely offline?

Yes. Android performs all operations locally, and the web app can run from a local host without backend services. Windows also runs standalone and supports CLI. Download binaries and firmware ahead of time to keep air‑gapped workflows. This suits lab, factory, and field environments. [Elektroda, p.kaczmarek2, post #21842603]

Will more chips and OS builds be added?

The author plans to port more chips with sufficient positive feedback. Linux and macOS builds are expected if feasible. Today’s focus is Beken with a basic UI, validating cross‑platform feasibility. “With enough positive feedback, more chips will be ported soon.” [Elektroda, p.kaczmarek2, post #21842603]
