I have created a custom code for ESp32 in Arduino IDE. I flashed the program directly from IDE using UART with the help of TTL. I'm looking for an alternative method to flash the firmware of ESP32.
I'm trying to flash the esp32 binary file generated from Arduino IDE, using the flash downloader tool.

I have used the configuration settings as follows
This settings flashed the firmware and the board reset worked perfectly. The SPIFFS did not however work.
Please find the log attached.
Also attached the reset log after flashing for reference
Thanks for the help.

I have a custom ESP32-S2-based circuit board with USB-C which does not have a USB-serial converter IC like a common dev board might. On this board, USB(-) is on GPIO19, and USB(+) is on GPIO20. USB works great for powering the board and for uploading firmware.
The board works well and I have access to good old-fashioned serial console via a USB-to-logic level serial interface, but it would be nice to be able to get serial out to USB along with the firmware upload (like a dev board).
I’m using PlatformIO in Visual Studio Code, and writing with arduino-esp32 rather than ESP-IDF.
I understand by these instructions from Espressif that when using ESP-IDF I can configure log output to go to USB CDC rather than UART, and this has been done successfully on my custom board. But I would like to be able to do this without having to switch over to ESP-IDF.
I’m presuming that one of the partitions that PlatformIO is building for me is this configuration with some nice common sense defaults, but I can’t see how I might alter those defaults to do what I’m looking for.
Any thoughts or pointers?
So, I programmed an ATMEGA32u4 and when I connect the device, it doesn't run the code. Instead, it gets recognised as an ATMEGA32u4 chip in Windows device manager.
To get the code running I have to open Atmel FLIP and open USB and then have to press the start application button after which it gets recognised as a HID in device manager and works as intended. I don't know why and what is happening.
The reset is pulled high with a 10k and the HWB is pulled down with a 10k and the chip has the factory bootloader on it.(if this helps)
Pulling down HWB is what you do if you want to start the bootloader built into the ATmega32U4. It sounds like you want to run your own code instead of running the bootloader so you should pull HWB up, or disable the HWBE fuse.
I'm new with NodeMCU firmware use. I have a Amica ESP-12E (v2?) dev kit connected to a DHT22 which I program using the Arduino IDE. All is setup and working fine.
My problem came when I wanted to update NodeMCU firmware. Since I don't really know what came pre installed from China, I downloaded ESPlorer to try to determine NodeMCU version. I get the following "error" when I reset the dev board:
Communication with MCU..Got answer! Communication with MCU established.
AutoDetect firmware...
Can't autodetect firmware, because proper answer not received (may be unknown firmware).
Please, reset module or continue.
{{a long string of weird characters that I can't copy and paste appear here}}
At this point I'm totally clueless about what version of firmware I have. Is there a way to obtain NodeMCU firmware version by software via Arduino IDE code, ESPlorer GUI or something similar?
On the other hand, is there a really easy way to compile/download latest NodeMCU firmware BIN file? Even one with all the modules active will be fine for me now, I'm just trying to understand and test things.
You seem to be confusing two very different platforms. I leave out some details as not to confuse you any further.
Arduino: you use Arduino programming in the Arduino IDE then build and install a binary to your device whenever the application changes. No NodeMCU firmware needed!
NodeMCU: you flash the NodeMCU firmware once (e.g. using esptool.py) and then upload Lua code (e.g. using ESPlorer) whenever the application changes. This is more lightweight than the Arduino platform.
On the other hand, is there a really easy way to compile/download
latest NodeMCU firmware BIN file?
Yes, have a look at the NodeMCU documentation at http://nodemcu.readthedocs.io/en/latest/en/build/. The easiest is to use the cloud builder at https://nodemcu-build.com/. I currently suggest to build from the dev branch because flashing is easier with it.
As pointed out you have several options for firmware and you'll need to make a choice as to which suits you going forward. If you are going to stick with the Nodemcu LUA firmware you can determine the version by typing:
print(node.info())
at the command line prompt.
There are alternatives to using ESPlorer e.g. Putty or Coolterm that will give you the raw output from the device with no interpretation. So if you have the correct serial port settings and the device plugged into the USB port it will show the banner when you reset giving an indication of the origin and version of the installed firmware.
In ESPlorer, there is an option under settings which if unchecked will stop looking checking for the version of the code.
For whatever reason, ESPlorer is not designed to read nodemcu version.
The error message throws you off, could lead you to think, there is an error.
At best, the above error can be ignored. It has no impact at all. In background, init.lua is up and running.
I have an Adafruit Ultimate GPS on a USB serial interface and using the same UWP application can read data just fine on a x86 build on a desktop. When I try a ARM build on the PI3 (remote), everything appears to work, but the serial data read never returns. No timeout, nothing. On the desktop, it starts getting GPS data from the chip right away. I also tried the CustomSerial sample app and am getting the same result. I do have the manifest updated to show serial port access, so don't think that is the problem.
Any ideas would be greatly appreciated. Thanks.
Problem resolved, operator error. Prolific driver not supported, was trying to read data from on-board serial port. Move the GPS sensor to the on-board serial, all is working now. Apologies for the distraction.
I am using spartan 3 fpga board , and as i am doing on linux i am using astriaekipro to flash the designs.
Till now it was working fine , but now it is showing that SPI flash ID do not match.
I have gone through the source code of the astriaekipro and commented the function for ID check and flashed it again.
Even after the complete flashing process, old design is not getting erased and new design not getting flased, i am only able to see output of the old design.
I am assuming the SPI Flash in FPGA is corrupted.
Any Suggestions Please
