OpenBeken W800 vs W806 Differences and OTA Update Methods

Question

What's going with this PR @divadiow ? Is W806 different than W800/W801? Btw, to answer OTA question - W800 has HTTP server based OTA (old OTA style), the Web App OTA is missing.

divadiow · Answer

good morning!

yes, I grabbed a Hi-Link HLK-W806-Kit-V1.0 board from Ali Express a week ago as it looked just like it's sister board the HLK-W800-Kit-1.0 and I wanted to see if OBK had any chance on it. I didn't really look at the spec when I bought it, but it doesn't have wifi/BT and it only has 1mb flash!

Without any research I tried flashing the W800 OBK but this unsuccessful, failing with this error

which led here http://ask.winnermicro.com/question/131.html

But then this caught my eye http://ask.winnermicro.com/question/720.html which led to this http://ask.winnermicro.com/article/186.html where this was stated:

Log in, to see the code

followed by the modifications to make to adjust SDK, which is where these initial changes were committed. https://github.com/openshwprojects/OpenBK7231...mits/53288ad592b05de359db926d30b770ef7a17e2d9

There were some failures because of size. This I think was the size that built

but then it would fail with

which I can't find mention of yet. Assuming this related to size I then set about trying to exclude bits to reduce flash total bytes, but you can see from subsequent runs this has not been successful yet. I've been commenting-out bits in the SDK relating to the demo, BT etc, but nothing I've tried has reduced size.

Even with a working OBK the 1mb flash probably makes it very limiting driver-wise, but still, it would be another supported chip to add to the list. Suggestions welcome!

How do you know that NAK error means that flash is too big? What is the current flash size? I can add some #define for you to for example allow turning off features like Tasmota JSON emulation

divadiow · Answer

I don't. Just a stab in the dark. But maybe it's related to NACK and it's that the flasher didn't receive an acknowledgement after Packets: 57/957? I've tried different uart speeds. 1mb! well that would be cool, but I am also happy to just keep playing myself if you've no time/other priorities. W806 was just a little adventure with no stakes.

p.kaczmarek2 · Answer

I don't think it's exactly 1MB, what is the current size of build files?

Can we get somehow some other binary for testing W806? I can try to help, I have linux vm, maybe we can build/compile something else together..

I can try to add more size build reduction within 3 to 6 hours from now so you can test more.

divadiow · Answer

I did wonder about that. Will try to find something. The board didn't seem to come with anything from factory. I can't yet post on the WM forums because I need more reputation points 🙄 well sure! that'd be awesome. Added after 1 [hours] 19 [minutes]:I'm trying to find evidence the W806 really does have wifi/bt cores. unsure yet Added after 2 [minutes]:I have a working LED blinky demo from woop

p.kaczmarek2 · Answer

How large is the working LED blink demo?

divadiow · Answer

tiny arduino sketch Added after 42 :flashes successfully in upgrade tools too

p.kaczmarek2 · Answer

900KB vs 90KB seems like a huge difference. Is OBK really adding that much? Or is your tiny sketch compiled without WiFi library itself?

divadiow · Answer

I imagine it's the bare minimum using a real W806 SDK with no wifi lib? Not sure blinky is any help tbh

these are all the files under AppData\Local\Temp\arduino\sketches\5FEE0DA0118E63E80FD53A32C4A29472 from the sketch compilation

p.kaczmarek2 · Answer

I'd suggest trying to make a simple AP demo with that Arduino thing. I will be able to make OBK build smaller in about 2h.

Added after 1 [hours] 51 [minutes]:

I added ability to disable Tasmota API:
https://github.com/openshwprojects/OpenBK7231T_App/pull/1236
But it doesn't seem make much difference:
W800 FLS (not OTA) - 966 824
W800 FLS (not OTA) - 976 336

I don't think it's OBK making that much of a difference, maybe we need to check there:
https://github.com/openshwprojects/OpenW800

Added after 1 [hours] 25 [minutes]:

maybe disable that:

divadiow · Answer

I think I'm losing interest. I don't seem to be able to get the size down undefining all kinds of things. Kinda doubtful about the wifi anyway. Not sure what to make of this response:

p.kaczmarek2 · Answer

So what is your current size of the build? Maybe can I help more?

divadiow · Answer

still

i'm probably doing something wrong. I'm commenting out/undefining but that doesn't seem to be making a difference. I'm making the changes to my OpenW800 submodule then pushing to my fork then pushing to remote main. it's triggering the workflow with the open PR so I guess my changes are making it up to the right place...

eg https://github.com/openshwprojects/OpenBK7231...mits/492f5436757622c5e304f465f9d41e616df82927

p.kaczmarek2 · Answer

Is your fork switched to your W800 submodule?

divadiow · Answer

I believe so. that's what I spent the first half the evening fixing. I started again with everything since the night before.

.gitmodules has

Log in, to see the code

Summary of My Setup:

Forks and Clones:

I forked the repositories OpenBK7231T_App and OpenW800 from the original repositories.
I cloned my forks to my local machine:
OpenBK7231T_App: C:\Users\divad\Documents\GitHub\OpenBK7231T_App
OpenW800: C:\Users\divad\Documents\GitHub\OpenW800
Submodule Configuration:

The OpenBK7231T_App repository includes the OpenW800 submodule.
I verified that the submodule URL in my OpenBK7231T_App repository points to my fork of OpenW800.

that commit showing the file changes I made in my submodule are making their way to the main app PR is evidence all is OK?

p.kaczmarek2 · Answer

Hey, what's the state of W806 flash attempt? How much size reduction is needed? Maybe it will be possible once we merge:
Testing OBK Config for Smaller Builds on OpenBK7231T - Feedback Needed
With new features, it's possible to even disable MQTT in the build and it gives a very good flash size reduction.

divadiow · Answer

sadly almost definitely not a thing trying to enable wifi on it. it's been put to bed. latest:

Log in, to see the code

https://github.com/board707/w80x_arduino/issues/40#issuecomment-2561380709

maybe it could be made to run with no wifi - but then you'd just get to watch the uart logs? or you'd have to somehow script all settings. Maybe OpenW806 Core Edition - without GUI

Added after 1 [minutes]:

Maybe I'll try flash to see if anything is different with latest smaller build

Added after 26 [minutes]:

not seeing sizetest2 builds that much smaller for W800. 950kb smallest I've seen I think.

Now without (own) NTP and TLS it's much smaller, thanks to @p.kaczmarek2 :-) Added after 1 [minutes]:You have been first again, sorry it doesn't work...

divadiow · Answer

to try on W806? yeh, kinda didn't think it would just had to scratch that itch

max4elektroda · Answer

I meant in realizing that the reduced image now could be a start for W806. But sure also to try at all

insmod · Answer

@divadiow can you check if this version works?

I found my W800 board, how to take a backup?
It apparently came with tuya firmware, which is odd for a dev board.

Hi thank you. I can't test until tomorrow. Sadly I don't believe there's any XT804 known backup method. None I've been able to find anyway. Maybe there's some xmodem way, no idea

insmod · Answer

Then i will test it myself, i wanted to preserve the firmware before flashing, but since there is no known way...

p.kaczmarek2 · Answer

i may have w800 if i manage to find it in this mess

insmod · Answer

Flashed it. No log output, but it boots and connects to wifi. The free heap space is depressing, only 29k is available.

Done, works?

Well, PR has "berry" in name but it has no berry I guess:

Screenshot of the OpenW800 panel showing an error after entering the command berry 2+2 in the command line.

Added after 1 [minutes]:

Heap on your "berry":


Info:MAIN:Time 248, idle 0/s, free 29280, MQTT 0(16), bWifi 1, secondsWithNoPing 183, socks 2/8

Added after 2 [minutes]:

let's flash main release and compare. Doing OTA to 1.18.92...

Screen with hardware and network details of W800 device, including IP address and firmware version.


Info:MAIN:Time 49, idle 0/s, free 29280, MQTT 0(3), bWifi 1, secondsWithNoPing -1, socks 2/8

Well actually, I see no difference in heap size..
I can get it lower with HTTP refreshes:

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:

insmod · Answer

Does release OBK print anything on TX0?

p.kaczmarek2 · Answer

Log output is present on main release:

Window of RealTerm program showing serial communication logs and port control panels.

Oops I managed to somehow break config and it's now in brand new AP state. Probably I reseted it (on main release) while it was saving flash and it has corrupted. But still...

Back on berry:

Screenshot showing W800 device info and an open RealTerm program window.

I can confirm there is no log output on your "berry " build...
