We are planning to use ESP32-S2-SOLO-N4R2.
We need 2 SPI peripherals for external devices and also need the 2MB PSRAM.
Does the PSRAM block SPI2 or SPI3 like on ESP32-WROVER?
Or are SPI2 and SPI3 both free to use?

Re: New SPI-Ethernet-Adapter without modifying esp-idf
I did not find another way than using ethernetif_input and modified ethernet_low_level_output, except using modified nettestif.c.
So my ESP-IDF is modified, but the QCA7000 works reliably with tcpip_adapter.

New SPI-Ethernet-Adapter without modifying esp-idf
Developing a QCA7000-Driver (Powerline-Adapter, similar to a SPI-Ethernet-Adapter) for the ESP32. I modified ethernet_low_level_output and ethernetif_input in ethernetif.c so that they are writing the buffers directly to/from the QCA7000. Is there a more elegant way to access the tcpip_adapter witho...

Re: wifi spams serial monitor
This also happens with the unmodified /examples/wifi/getting_started/softAP/
A guy over at the Chinese Espressif Forum also has this behaviour.

wifi spams serial monitor
Hi, I combined /examples/wifi/getting_started/softAP/ + /examples/protocols/http_server/ Connection and http requests/replies work fine. But sometimes I get a lot of wifi messages on serial (30 per second): ... wifi: ampdu: ignore deleting tx BA0 wifi: ampdu: ignore deleting tx BA0 wifi: ampdu: igno...
