You can try removing not essential files from /Data folder.

So I solved this issue by soldering a new board and making sure I get a blue pill with a genuine STM32. Which of them was the actual culprit I don't know, but now I have the parameters in the web interface and everything works out of the box.

I know for sure that the first Blue Pills came with clone stm32 chips. I also can't rule out dodgy soldering first time round.

No parameters are showing but when I try to Display Error Memory I get:

Code: Select all

Unknown command sequence

Custom command 'json' gets

Code: Select all

So it seems that they are communicating as from the forum search this error is something that the stm32_sine sends back. But TX may be messed up somehow? I believe my Blue Pills may be quite dodgy .. so would want to put the black pill on there instead but the pin labels are not exactly the same. Any ideas? Much appreciated!

Have you clicked on refresh?

Are any of the LEDs on the blue pill blinking, or are they on solidly?

...

I bet you made the same mistake I did. There is supposed to be a blinking LED if you flash the firmware successfully.

Did you flash the bootloader file before you flashed the SINE or FOC file?

See my failures (and the previous forum page), if that's true:

TX goes to RX.
RX goes to TX.

Maybe try rebooting them.

Other than that I'm coming up blank.

How about serial link speed?
If you were to connect a USB/TTL converter then you could check the serial link speeds, and see if any data shows up. The STM32 sends "2D" upon powerup or reset, and if you send 'json' it should spit out lots of stuff. Newline character is required.

I believe my STM32 talks at 115200baud (although my ESP died rather randomly and exhibits similar symptoms) so that could be a good starting point.
I will need to work on a ESP for myself soon enough. Best of luck in the meantime!

Hmm, I'm not sure I'm much help past this point because I didn't use the Olimex board.

What's your procedure you're following, and where is it failing or not getting results?

I can suggest to "put on your programmer's hat on" and try to troubleshoot beyond ESP. Try to connect TX/RX directly into USB-TTL dongle (CH340/PL2303 ...of course with proper drivers installed). Open "putty" https://the.earth.li/~sgtatham/putty/la ... taller.msi and see if you can connect to Blue-Pill (selecting right COM and speed)

UPDATE: After trying the available memory size options, I finally got everything to load!!!! Sill "FileNotFound" @ 192.168.4.1 however... UGH

Yet ANOTHER update..... SUCCESS!!!!!!!!

I have the same issue. Using Olimex Mod and Arduino IDE to flash. All seems to go ok but on the 192.168.4.1 page I get "file not found". What did you do to fix this?

I have a feeling this is one of those things where the instructions either aren't being followed, or, aren't correct for the very first time someone sets something up.

Else, a procedure should work exactly the same for everyone.

David - What procedure are you following? Link to it so we can know exactly what you did.

Getting File not Found when you go to the IP doesn't tell us much troubleshooting-wise other than that there's nothing at that IP. This could be because you did literally nothing, or that you got 99% of the way.

It could be something as simple as, you're connected to the wifi in your home rather than connecting to the ESP8266. You haven't given us anything to help you with.

Thanks for your reply Matt.
I have a Olimex Mod board and been trying to program with the Arduino IDE . I've got the boards loaded in the IDE. I've connected the board to USP-TTL as per instructions on page 1, moved solder bridge to 0.
Created folders with ino and data. as per arbers instructions on page 3.

If I open the ino file and with the correct board and port selected I can program the Olimex, everything appears ok. It gets to resetting the board and just sits there.

Then I've tried either waiting a while and trying the ESP data upload tool or manually resetting the board by powering it down and then trying. Either way it appears to load the SPIFF and gives completed messages.
I'll try again and take some screen shots.

Then on my phone I am changing to the ESP wifi and attempting to go to 192.168.1.4 and get "FileNotFound"

All debug looks good, steps followed correctly. Maybe there is a bug with URL "/"?

Perhaps try full URL? -> http://192.168.4.1/index.html

And I'll just reitterate... on whatever device you're using to access the 8266, you're connecting to its wifi, not your home wifi, right? Could be a firewall issue too on your side.

What are you using to connect? Desktop, laptop, tablet, phone?

Yes Matt, I'm Connecting to the ESP wifi Via my iphone.

If I just try going to 192.168.4.1 without changing wifi I get site cannot be reached errors so definitely on the ESP.

Are there any files I've missed in the SPIFFS load?

Ok tried it on a Wemos Node Mcu Lolin and it is the same. must be something i'm missing.

Had a play with the ino code to see if I can debug. Changed the 2 "file not found" messages to "filenotfound1" and "filenotfound2"
Now i'm getting a file not found 1 message when I try to access webpage.

Did you set maximum SPIFFS size?
Why not try command line?

Need these tools:

• Python 3.7+

• mkspiffs.exe

• esptool.py
