Erros when trying to dump certificates from ESP32 box

Software TeddyCloud
1

Hi,
I’m getting a bunch of errors when trying to dump certificates from my new and untouched firmware of a ESP32 toniebox.

  • reading the firmware was successfully done via webgui
  • teddycloud is running in a docker container via the “official” docker compose yml (unchanged, expect port mapping 4040:80)

First issue (missing config files):
to me this seems like some mismatched path. within my docker there’s not path like:

/teddycloud/data/firmware/config/

The missing files sitting in the following path:

/teddycloud/config/

there’s nothing in firmware folder execpt the firmware bin file

Second issue: “File does not exist or is too small ‘data/firmware/ESP32_xyz.bin’”
the firmware dump is 8MB in size, is this correct?

Complete Error message after running

teddycloud --esp32-extract data/firmware/ESP32_<mac>.bin --destination certs/client

I assume you did not changed any setting in teddycloud?

3

No, except the port mapping mentioned above in the docker yml.

I also disabled “Webinterface HTTP only” in the old webgui. new webgui is completely untouched by me.

4

both webguis share the same settings.

but you are right, the mentioned path sounds wrong. lets wait for @0xbadbee , he can help i think.

The filesize looks ok, it should be 8MB.

Did you stopp the docker? It looks like it crashed… maybe you can change the settings a little bit and set the log level to 6 (maybe you have to increse the Settingslevel to expert first). than there will some more log entries.

5

No, this is just leak information.

Where are you running the command? It looks to me that your are running the command in data/firmware

6

thank you, works like a charm now. issue was indeed executing the command from the wrong path
