There are some warnings generated when I build I would like to suppress those warnings. I dont want to change anything in the ESP-IDF tool chain. Is thi...

Hi, yes. That i tried. We doubled the stack size with the same result. Eventually we get a stack smash

Stack Smashing from the BT stack/ROM code

Hi I get stack smashing from time to time. It is detected during task switch, so the call stack does no reveal that much. I can see it is related to the BT stack and happens with in some hours of usage of the BT connection. Stack smashing protect failure! abort() was called at PC 0x4015dc53 on core ...

Memory usage explanation

Hi all I wonder how to understand the used memory after I have build my application. As I understand there is a total of 520 K of RAM. 320 K can be used for data. But the memory overview show that the DRAM region only is ~180 K? I have configured a minimal system with basically only the FreeRTOS ena...

sdkconfig and sdkconfig.h issues

Hi I probably is doing something wrong, but I have some difficulties to generate a usable sdkconfig.h file. Sometime it revert to something different that I have made in menuconfig I have ESP IDF v4.4.1 and using visual studio and CMake My application folder: Esp32Config sdkconfig main main.cpp Cmak...

Re: Enabling EMAC clock makes jtag stop

Hi

That did the trick. Now it all works, thanks
Yes, the RMII clock is also solved. There where some other electrical issues with wrong resistor values etc.

Enabling EMAC clock makes jtag stop

Hi I think is is related to noise and a 50 MHz oscillator for the EMAC. I use a ESP32 WROOM with an external 50 MHz oscillator. I use the IO33 from the ESP32 to enable the PHY and the oscillator. The IO0 is used for EMAC clock in But as soon I enable the oscillator and PHY, setting IO33 high, the jt...

Problem writing to the EMACMIIADDR_REG

Hi I try to setup PHY commands. I have MDC and MDIO on IO2 and IO4. PHY address is 2 If i try to set the PHY address to emacgmiiaddr.miidev and than do a read back, the register is not set to the PHY address of 2: emac_ll_set_phy_addr(hal->mac_regs, phy_addr); // Readback to check if (hal->mac_regs-...

Software reset (SW_RST) timeout of the EMAC?

Hi I have a ESP32 WROOM using my own board. Using a KSZ8081 PHY and external 50 MHz crystal. I'm using GPIO0 as clock input. The oscillator is controlled with the RESET_N signal, so I dont accidentally starts the bootloader. Al signals seens to work. But the reset bit of the EMAC never get cleared (...
