Re: very low ethernet speed using ksz8863 on ESP32D0W

Hi. We removed the 49.9R and put a 0R instead. The pull-down is not currently soldered to the PCB in our board. We tried both mode 5 and mode 3 as suggested (setting p3_rmii_internal_clk accordingly) We also tested that CLK was present at GPI0 but without success. The error we face change between a ...

Re: very low ethernet speed using ksz8863 on ESP32D0W

Thank you very much for your response. We tried with the iperf code you provided (changing the values of the I2C, P3 and so accordingly). My coworker, who develops the hardware part, have looked at the schematics and according to him we have almost the same schematics with the only difference we are...

Re: very low ethernet speed using ksz8863 on ESP32D0W

Sorry, I thought that if someone had similar problems that information will be enough. Yes I created an echo server using TCP sockets, the server reads the number of bytes to read and then reads that number of bytes. When testing the same using a different hardware it works properly so I don't reall...

Re: very low ethernet speed using ksz8863 on ESP32D0W

I followed simple_switch example (https://github.com/espressif/esp-eth-drivers/tree/master/ksz8863/examples/simple_switch). For the throughput I sent a 5 KB buffer to the ESP and receive the same buffer from the ESP and then I calculate how many time it take and calculate the throughput. The ESP is ...

very low ethernet speed using ksz8863 on ESP32D0W

Hello. We faced some difficulties while we tried to send data through ethernet using the official driver for ksz8863 chip (https://github.com/espressif/esp-eth-drivers/tree/master/ksz8863 ). The transmission speed is very low, ~13KB/s, that's incredibly low bandwidth. For this setup we connected the...

Re: When esp-idf v5.0 will be available

Hi. I'm also interested about this. It have been 3 years since the last post and version 5.0 isn't released yet. Is there a release plan for version 5.0

Thank you

[SOLVED] How to detect code being compiled for esp32

Hi. I have a shared code between the esp32 and the host system. I was seeking a way of knowing when a code is being compiled for esp32, I know I could do somethine like #if defined(__linux__) || defined(__APPLE__) #else #endif but as this code may be compiled also for windows and maybe BSD I would p...
