Re: ESP32 can not initialize IP101 Ethernet PHY
Sorry, for such a late response, I spent all this time debugging. Here is m update: I am trying to replicate ESP Ethernet DEV kit (at least the ethernet part of if) on my custom PCB that I will be using for Ethernet application. I consistently followed the manufacturer's schematic (in the attachment...

Re: ESP32 can not initialize IP101 Ethernet PHY
Yes, I have. Like I mentioned, it seems there are no problems with the ESP32 itself, I am getting the right voltages, no shorts, no suspicious current consumption, other than the PHY, PCB works as intended.

ESP32 can not initialize IP101 Ethernet PHY
Hi, I have spent a lot of time developing some ESP32 ethernet application on a genuine ESP Ethernet development board. I wrote a very long code that worked flawlessly on my testing hardware setup. Now I am implementing all that on a custom PCB. I can flash and get logs from ESP microcontroller, so I...

Re: ESP-DOWD-V3 in custom PCB would not flash...
I can not even initialize the terminal communication. My terminal does not post any status flags about the chip.

I have already done everything you mentioned. No problems in these steps.

ESP-DOWD-V3 in custom PCB would not flash...
Hi, I a have a very typical problem, yet in not so typical circumstances... I made a PCB that has an exact same replica of ESP32-WROOVER-E only embedded in the PCB directly rather than using off-the-shelf module. It took me a lot of time and effort examining the datasheets and reverse engineering th...

SRAM and FLASH memory considerations on replicating ESP32 WROOVER-E on bare PCB
Hi, I am doing a project where I want to build and ESP32 WROOVER-E on my custom PCB (I wont be using RF communication, so avoiding ESP SoC brings me a lot of benefits.) I have examined various datasheets and documentation papers, however, I am still not sure about the memory ICs of ESP32. I have del...

Re: Embedding assembly code fragment in main source file in ESP-IDF
Reading the datasheet implies that it is still worth trying. So can you provide me the assembly details? I tried to do it by myself, but ESP-IDF was giving me syntax errors. Does anyone have a very simple and working assembly block syntax template?

Embedding assembly code fragment in main source file in ESP-IDF
Hi, I am developing a code (on ESP32 WROOVER-E) that could potentially hugely benefit from rewriting some short fragment of C code in assembly language. Having said that, I still want to preserve the rest of the source file unchanged. Can you please provide me with some short snipet or pseudocode wh...

ESP32 WROOVER-E always reads GPIO inputs as zero
Hi, I am developing a quite complex application involving TCP networking and parallel ADC sampling. This code is going through quite some commands and has many functions, but please focus only on app main. The idea is that at first ESP32 goes through some UDP broadcasting - IP recognition (with serv...
