hi guys, thanks for the great work on it. JTAG Debugging for ESP32 V 1.0 2017 March 1 PDF This document provides a guide to installing OpenOCD for ESP32 and debugging using gdb in a Linux virtual machine. it comes with a debugging example.

Sorry, no idea whether that works with EMAC (there may be more settings needed to make EMAC actually use this clock), but at least it gets 50MHz out of IO16. Hope this helps. Edit: rtc_plla_ena function signature may change, this function may be removed, you may get eaten by raptors if you use it, ...

I know I can disconnect it by adding a switch controlled by a GPIO, but there is no more GPIO left. sry i do not know, how much pins you use in your project, i do not know your project, so perhabs you can tell about more, like i asked, would be helpfull to answere your question, which board or envi...

asap WiFive (not today) , i am on other place now. do you see, allways the same buzzy waves, on pos and neg ( inverted ) edit: Like a pattern, watermark noise ;-) edit: add a play on pic ( cut and paste the pos and neg ) watermark_pattern_bit.jpg with 32.5 MHz is comming a "compensation". best wishe...

.. there is no clock enable/disable option via software programming. then you must do by self: #define PIN_PHY_POWER 17 .. void phy_device_power_enable(bool enable) { gpio_pad_select_gpio(PIN_PHY_POWER); gpio_set_direction(PIN_PHY_POWER,GPIO_MODE_OUTPUT); if(enable == true) { gpio_set_level(PIN_PHY...

Colman

do you use the LAN8720 Modul , the LAN8720 EVB from MC or own circuit?
is your gpio 0 pulled up? which value?

Hi WiFive

1,2,8
12MHz

@ivan
thanks for the hint!
now i figured it out, ESP32 ETH PHY RMII with own 50MHz Clk for Refer and X_in
done!

i will forward code ect to robin and angus after clearing all
it takes few days for testing - and then upload

Very cool Rudi. How are you generating the clock? hi robin try this: .. #include "soc/emac_ex_reg.h" extern void rtc_plla_ena(bool ena, uint32_t sdm0, uint32_t sdm1, uint32_t sdm2, uint32_t o_div); .. PIN_FUNC_SELECT(PERIPHS_IO_MUX_GPIO16_U, FUNC_GPIO16_EMAC_CLK_OUT); REG_SET_FIELD(EMAC_EX_CLKOUT_C...

hi robin, hi www220 have plan to do on weekend , but could not wait: ESP32 generate 50 MHz for xRefer and X_in ( LAN8710A ) clk ok, SMI ok, now create the header for LAN8710A for DHCP and IP IMG_6055_s.jpg ( clk small curved cause have not filtered pinheader ) IMG_6048_s.jpg now we have tlk110 LAN87...
