Hi Pablo,
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,

Anything remotely interesting could be relevant.
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 ...

. So my suggestion - try to check if something is blocking outgoing connection...
