I've setup a basic system using the ethernet example at https://github.com/espressif/esp-idf/tree/master/examples/ethernet/basic

Now I would like to be able to power down the ethernet PHY (LAN8720) at runtime by accessing its Basic Control Register, which is located at SMI address 0x00. Which ESP32 ...

The Espressif tools contain a tool called `xtensa-esp32-elf-addr2line` which will interpret the addresses for you and give you proper information about the source files, lines and function names, etc. You can feed it the entire backtrace and it will display the info for all addresses in one swoop ...

How do you decode stack traces like this one:

abort() was called at PC 0x40158ccb on core 0

Backtrace:0x40088eba:0x3ffc5030 0x40089601:0x3ffc5050 0x4008fc62:0x3ffc5070 0x40158ccb:0x3ffc50e0 0x4008c1b5:0x3ffc5110 0x4008c27d:0x3ffc5130 0x4008c585:0x3ffc5150

What I've been doing so far is dump the ...

Our ESP32 seems to lose Wifi connection after about 15 minutes of operation.

Here's what I'm seeing in the logs:


D (895423) wifi:recv deauth, reason=0x3
I (895423) wifi:state: run -> init (3c0)
D (895423) wifi:recv deauth/disassoc, stop beacon/connect timer
D (895423) wifi:connect status 5 -> 4 ...

I need to upgrade my ESP32 code to use a client certificate for secure communication with a remote server.

So far, I've used the library to issue the HTTP requests but as far as I've seen, this library doesn't support client certificates. What are my options?

Thanks,
Guy.
