HOWTO: Flashing ESP8266

[james@N52E01]

Dima and Arber I tried as you both suggested but still no luck unfortunately. Just to confirm, I am not using the -DEV board, it is the MOD-WIFI-ESP8266 with the UEXT header like your picture on the original post.

With these settings you posted above and an FTDI board connected as you originally posted, have you or Arber successfully managed to flash one of these boards with the latest Arduino IDE and esptool.py v2.6?

Yes all the time. Only difference not using expensive FTDI (You will need USB to TTL not RS232 Serial) Prolific2303 or CH340 work. (-DEV) is in brackets IDE builds for both.

I'm having a similar problem as well. I got the ESP8266 from Johannes so it should be fine. Then programmed the bootloader and stm32_sine.hex red led is on and green is blinking on the blue pill.

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

Code: Select all

Unknown command sequence
e��K�
Unknown command sequence

Custom command 'json' gets

Code: Select all

Unknown command sequence
j��)

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!

I flashed another esp8266 with Dima's interface and no luck on either Blue Pill nor fully tested GS450h-VCU. On both I get the error: ' SyntaxError: JSON.parse: unexpected end of data at line 1 column 1 of the JSON data:'.

GS450h-VCU will not work with Johannes or my web-interface. You will need to flash this https://github.com/jamiejones85/ESP8266-WiFi-Interface. Blue-Pill was not tested by me.

This means wrong serial speed! 15200 is what you want.

FYI if the sketch and the SPIFFS will all fit on a 1MB chip (like Damien's interface for the GS450h) I was able to use the super cheap ESP-01. You don't have to solder pins, just connect 2 extra pins while flashing. It made it easy practice (especially when you are modding code like me) before having to move the solder around.

How did you get the sketch and the spiffs to fit on the esp-01.
What did you change to get it to work ?

I have a esp-01 here that I try to use.

I followed this post:
viewtopic.php?p=5048#p5048

But for step 6 I choose the "Generic ESP8266 module"

That worked for me.

I used FTDI Cable with RTS connected. That worked perfect.

But you need to keep the enable pin high all the time.
And when flashing pull the GPIO0 low

Hi ZK!

I'm using win10. It worked fine.

I created a FSBrower dierctory.

extracted Johannes FSBrowser project

In the FSBrowser dir I created a Data directory.

Moved all files except the FSBrowser.ino file into

Then opened the the .ino file.

First uploaded the sketch.

Waited for the a couple of seconds after reset of ESP

Then uploaded the Spiffs.

Then removed the flash pulldown.

That worked for me.

It sounds like your "Data" folder is empty, Johannes web interface folder structure does not reflect what is needed for Arduino IDE - ESP8266 SPIFFS Uploader.

make C:/FSB <-copy only FSBrowser.ino
make C:/FSB/Data <- Copy all files except FSBrowser.ino

Yup, thanks!! Olimex on the way so I have enough memory, apparently the ESP-01 does not

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

Code: Select all

gauge.min.js.gz
gauges.html
gauges.js

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.

I'm having a similar problem as well. I got the ESP8266 from Johannes so it should be fine. Then programmed the bootloader and stm32_sine.hex red led is on and green is blinking on the blue pill.

Have you clicked on refresh?

[MattsAwesomeStuff]

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

[MattsAwesomeStuff]

BluePill & Olimex have solid red LEDs

...

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:
