Hi,

I'm trying to set the hostname for the ethernet interface.
But `esp_netif_set_hostname()` always returns `ESP_ERR_ESP_NETIF_IF_NOT_READY`.
`esp_netif_get_hostname()` also always only returns `ESP_ERR_ESP_NETIF_IF_NOT_READY`.

I've checked the source code of these functions and they look like ...

Hi,

I enabled CONFIG_SECURE_SIGNED_APPS_NO_SECURE_BOOT in my project to have OTA updates validate the binary.
I've added a private key file and enabled the sign during build option. The build system indicates that it performs signing operations after build using the correct key file. After building ...

Hi all,

I can flash it just fine with the following command:
openocd -f interface/jlink.cfg -f target/esp32-solo ...

This error usually means that other firmware on the ESP32 blocks the JTAG pins.
Note that when you buy a fresh board it's usually flashed with AT firmware, which will indeed block the JTAG pins.
You can prevent the AT firmware pin from ...
