Callback does not return when uses object being used n the other core
Not sure if it belongs to this Forum (ESP-IDF) I just want to understand what is happening internally So I have an object whose class provides two methods one FPGA_handler() which takes a few variables, makes some computations, orders them as a bitstream and sends them via a spi channel. This method...

Re: Issue on esp_eth_mac.h
I have exactly the same problem (Exactly, the same as you described it)
Did you find a solution?

Re: How to receive spi transmission inside a defined struct, order of MSB and LSB does not match
This first byte seems to be lost. Possibly because it is already sent by the FPGA while the ESP is in the "address" phase of the transaction. Do away with the "addr" of the SPI transaction and include the address in the TX data. Hmm, that was indeed the reason... The FPGA code is designed to be lit...

How to receive spi transmission inside a defined struct, order of MSB and LSB does not match
I'm working on a project involving an ESP32 interfacing with an FPGA. I've run into an issue when transferring ADC data from the FPGA to the ESP32 using SPI. I have developed a c library that contains a few structs like this: typedef uint16_t adc_ch_sample_t; typedef struct{ adc_ch_sample_t INA1; ad...

Re: [ESP32-S3]Concatenating 2 devices over JTAG
The CPU JTAG signals can be routed to the USB Serial/JTAG Controller or external GPIO pads using eFuses and when the user program has started, software control as well. At that time, the JTAG signals from the USB Serial/JTAG can also be routed to the GPIO matrix. This allows debugging a secondary S...

[ESP32-S3]Concatenating 2 devices over JTAG
Hi, I have been wondering if I could concatenate a ESP32 and another microprocessor/FPGA JTAG. If I have something wrong over my assumptions, please let me know. I know that the ESP32-S3 has a USB Interface that hosts a JTAG controller and Serial interface. Also, the ESP32-S3 has JTAG pins exposed, ...

I have seen 2 other post, with the same issue: viewtopic.php?t=22478
Does anybody know what might be going on?

Re: Ping to ESP32 with different results, between station_example and other examples which use example_connect component
I wouldn't say it is an "issue" more like a performance hit, I guess I started seeing it on my app, but tested it on the https simple example https://github.com/espressif/esp-idf/tree/master/examples/protocols/https_server/simple and the wifi connect example https://github.com/espressif/esp-idf/tree...

Ping to ESP32 with different results, between station_example and other examples which use example_connect component
So I have been testing the code for a project of mine, that has a wifimanager developed by me, and uses othere components as mqtt and https. For some reason (that is not important in this topic) the https didn't work in my code, so I decided to test the https simple example, to see what might be goi...

Using the same ssl certificate for multiple components
Maybe it is some kind of a stupid question, but I was just wondering if we can use the private keys and public keys in multiple components, for example for a https connection and a MQTT client with a secure connection. Also, when is it and is not recommended to use a secure connection? I mean, havin...
