what am I doing wrong ??? ESP32 flashing

[uhi22]

This is the part of the console output which shows the download of the software. This looks good, but more interesting would be to see what comes afterwards. In https://github.com/jsphuebner/esp32-web ... n_notes.md I noted

[medo]

there is nothing in it

[medo]

if i make e full clean and erase flash, and then i make a build, then it looks like this

If I build again, it will look like this

then the upload works

then upload the filesystem

on the Serialmonitor looks like this

but still no wifi

[uhi22]

Strange. You could add some further instrumentation in the code, to find out where it stops. Go to the setup() function, and find the DBG_OUTPUT_PORT.println("No RTC found, defaulting to sequential file names");
This still works, we see the output in the console.
Add below this further lines like
DBG_OUTPUT_PORT.println("step 1"); Serial.flush();
The Serial.flush makes sure that the serial data is really transmitted, before the next step is done. Example:

It looks like sd_mmc is causing problems

I've now commented out that part, but it just doesn't continue

[uhi22]

Nobody needs this, just delete the SD card things completely
(Johu will beat me for this sentence )

[medo]

I was also wondering why an SD in a controller board, but I think the firmware should be universally applicable

[medo]

I think the esp32, just stop there, unfortunately I don't know why

[uhi22]

Maybe the SD card driver is not happy with something. Just remove everything related to SD card from the code and try again.

[medo]

I have removed everything related to SD card, now i have wifi and can open the web interface,
but now I don't have any values, probably deleted too much in the code, unfortunately I'm not familiar with it

[johu]

Will check later if the correct uarts are selected.

[johu]

sigh...
the uart-backend branch was outdated. Now it has the correct UARTs specified. Please pull again and then remove the SD card code again....

[medo]

Unfortunately I don't know how to do that, I don't know enough about Arduino

You did it before but can't do it again?
Download esp32-web-interface.ino here https://github.com/jsphuebner/esp32-web-interface and replace the one you used before. Remove the SD-card code as you did before

[medo]

I did that, but no data comes from the controller

It might be the mismatch in stop bits between the stm32 terminal and the ESP32. I've only used the ESP8266 with uart but had to modify the stop bits to 2 for the initial 115200 baud rate.

[medo]

I think there is still an bug in it, if I install the stm32 firmware, then I no longer have WiFi, if I delete the firmware again, WiFi is available again immediately

OK, I changed that

uart_config_t uart_config = {
.stop_bits = UART_STOP_BITS_2,

and that
uart_read_bytes(INVERTER_PORT, &c, 2, UART_TIMEOUT);


works and values are displayed, and changes are also applied, but when I switch it off and switch it on again, then no wifi again, until you have deleted the st32 firmware, then wifi is back immediately
