I'm doing some test with OTA but when I'm trying to upload a new sketch, I got

Booting
Ready
IP address: 192.168.0.216
Error[1]: Begin Failed

I'm using Arduino IDE 1.8.5 under gentoo/linux.

What should be the cause of this error and how can I solve it ?

Thanks

Edit: My bad - I overlooked Linux . So my suggestion - try to check if something is blocking outgoing connection...

Please give as much information as you can: setup, script, used power supply, pictures (we love pictures), things you've tried yourself, what are your expectations and what are the results, etc. etc.
Anything remotely interesting could be relevant.

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.

There is no firewall on my Linux and both the ESP and my PC are on the same network. So I don't think there is anything that can block.

Hi QuickFix,

Please give as much information as you can: setup, script, used power supply, pictures (we love pictures), things you've tried yourself, what are your expectations and what are the results, etc. etc.

I duno which additional information I can provide :

• I installed BasicOTA (with my own network settings obviously) on an ESP-201
• When I boot it, I can see from it's serial console it's connecting and get an IP address.
• A new port is created on my Linux box's IDE 1.8.5
• the IDE successfully connect to this port as the transfer is initiated ... but I got the "Error[1]: Begin Failed" error on ESP's console.
• it's the same power supply I'm using to burn on ESP all my project without any error and I've put a 470uF capacitor close to ESP power pins
• Sadly, I don't have any photo by hand but a nice video (unfortunately without any relationship with my issue) of my hens .

Anyway, I've tied to trace this error on library's code : it's raising from ArduinoOTA.cpp's

Code: Select allvoid ArduinoOTAClass::_runUpdate() {
  if (!Update.begin(_size, _cmd)) {
#ifdef OTA_DEBUG
    OTA_DEBUG.println("Update Begin Error");
#endif
    if (_error_callback) {
      _error_callback(OTA_BEGIN_ERROR);
    }
...

And as per Updater.cpp, Error[1] means "Flash Write Failed" which come from

Code: Select allbool UpdaterClass::_writeBuffer(){

  if(!_async) yield();
  bool result = ESP.flashEraseSector(_currentAddress/FLASH_SECTOR_SIZE);
  if(!_async) yield();
  if (result) {
      result = ESP.flashWrite(_currentAddress, (uint32_t*) _buffer, _bufferLen);
  }
  if(!_async) yield();

  if (!result) {
    _error = UPDATE_ERROR_WRITE;
    _currentAddress = (_startAddress + _size);
#ifdef DEBUG_UPDATER
    printError(DEBUG_UPDATER);
#endif
    return false;
  }


Investigation still on going ...
