Hoping for some knowledge from the brains trust here. I have been battling with a problem with the Arduino IDE for several weeks where I cannot upload to a Wemos D1 mini via the usb port, on all three computers, all running Ubuntu 20.04, Arduino 1.8.13, and esp core 3.0.2 but also tried 3.0.0 and 2.7.4 from GitHub.
I have been playing with the Wemos D1 mini's for a few years now and are usually having no trouble uploading via USB. I can upload to AVR boards via USB without problem. It seems specific to the esp8266 based boards.
The fault I get in Arduino is as follows:
Arduino: 1.8.13 (Linux), Board: "LOLIN(WEMOS) D1 R2 & mini, 80 MHz, Flash, Disabled (new aborts on oom), Disabled, All SSL ciphers (most compatible), 32KB cache + 32KB IRAM (balanced), Use pgm_read macros for IRAM/PROGMEM, 4MB (FS:1MB OTA:~1019KB), v2 Lower Memory, Disabled, None, Only Sketch, 115200"
Executable segment sizes:
ICACHE : 32768 - flash instruction cache
IROM : 355044 - code in flash (default or ICACHE_FLASH_ATTR)
IRAM : 29385 / 32768 - code in IRAM (IRAM_ATTR, ISRs...)
DATA : 1524 ) - initialized variables (global, static) in RAM/HEAP
RODATA : 2736 ) / 81920 - constants (global, static) in RAM/HEAP
BSS : 28368 ) - zeroed variables (global, static) in RAM/HEAP
Sketch uses 388689 bytes (37%) of program storage space. Maximum is 1044464 bytes.
Global variables use 32628 bytes (39%) of dynamic memory, leaving 49292 bytes for local variables. Maximum is 81920 bytes.

This report would have more information with

option enabled in File -> Preferences.It looks like a Python fault, but thats ...errrr.... above my pay grade. ;-)
This is what's weird. If I run a VM Win7 from within the same Ubuntu 20.04, I can upload via USB no problem from the windoze Arduino ide which is running in the VM on the Ubuntu host.
No doubt someone is looking at this and slapping their forehead while muttering "why doesn't he just do ??this", but the solution is not obvious to me. Any help would be appreciated.
Sorry 'bout the formatting.
Seems esptool or Python is the issue.
Check your kernel version. There was a regression in a late model Linux kernel in a USB-to-serial driver that made it incompatible with the way ESPtool uses it.
Fixed in linux mainline, no idea if it's fixed in Ubuntu kernels yet
@earlephilhower:matrix.org That helped a lot. Thank you. Seems 5.4.0-89 and 5.4.0-88 are both affected. The only other kernel I have loaded is 5.3.0-050300-generic which cured the fault.
So deciding if I go further an load other kernels looking for the point of failure or just sit on 5.3.0 and wait for an update.

@earlephilhower:matrix.org I have ported the BearSSL library to the ESP32 and I am currently working on a generic Client that takes another Client as parameter in it's constructor and adds TLS to it. probeMaxFragmentLength() is already working, dynamically creating the IO buffers, as is setting certificates as TAs. Also I think I can get setInsecure() and fingerprints going. However, allowSelfSignedCerts() will be difficult. But what is the real reason for this method? It is almost the same as setInsecure() apart from checking a self signed cert. But if someone wants to spoof the server, adding a self signed cert is very easy. What is the added value of checking self signed certificates?
@Jeroen88: That's a good question. This method was added to support axTLS backwards compatibility. I would not add it to a new port. There really is no added security with it.
@d-a-v:matrix.org I noticed LWIP 2.1.3 was released recently - https://lists.nongnu.org/archive/html/lwip-users/2021-11/msg00001.html. Are you all planning to pull it into the core?
Hi, I'm on master and am getting a Software WDT Reset on this line https://github.com/esp8266/Arduino/blob/master/libraries/ESP8266WiFi/src/ESP8266WiFiGeneric.cpp#L626, would there be anything on my side that could cause this? or it's probably a bug?

Is it necessary on the ESP8266 to set the
pinMode(A0, INPUT), when using the analogRead(A0) function?

Hi guys, is there an wax to query the actual
rf_mode?WAKE_RF_DEFAULT, WAKE_RFCAL, WAKE_NO_RFCAL, WAKE_RF_DISABLED. (GPIO16 needs to be tied to RST to wake from deepSleep.)
The chip can sleep for at most ESP.deepSleepMax() microseconds.
If you implement deep sleep with WAKE_RF_DISABLED and require WiFi functionality on wake up,
you will need to implement an additional WAKE_RF_DEFAULT before WiFi functionality is available.
If I can set the
RF_MODE is there a possibility to check it after boot?
the only router wpa3 that I have don't seem to work like this.
hello to all a little question I can not upload on the ESP 8266 card its given that, serial.serialutil.SerialException: could not open port 'COM4': FileNotFoundError(2, 'Le fichier sp�cifi� est introuvable.', None, 2) following a search on the internet that is good for the 'COM4 port that is not installed but I do not know how to do the installation of the install you can help me thank you.
Hi, could someone help me understand this crash please?

It seems HttpClient::begin returns true, right after the TCP connection is closed, and then getString crashes, is there a way to catch the problem that I'm missing, or is it a bug?

Does that make any sense?
have you traced esp_delay args? does hostByName lock (see static var it uses for callback) never gets reset, somehow?
Hi Max Prokhorov, you mean something like this?
template <typename T>
inline void esp_delay(const uint32_t timeout_ms, T&& blocked, const uint32_t intvl_ms) {
const auto start_ms = millis();
while (!esp_try_delay(start_ms, timeout_ms, intvl_ms) && blocked()) {
std::cout << timeout_ms << " " << start_ms << " " << intvl_ms << " " << blocked() << "\n";
}
}
bool esp_try_delay(const uint32_t start_ms, const uint32_t timeout_ms, const uint32_t intvl_ms) {
uint32_t expired = millis() - start_ms;
std::cout << expired << std::endl;
if (expired >= timeout_ms) {
return true;
}
esp_delay(std::min((timeout_ms - expired), intvl_ms));
return false;
}Logs:

Soft WDT reset
It doesn't seem to explain much tho, it seems to always call esp_delay, which should yield, right?
Isn't reset cause 2 a fatal exception? Is the decoder confused and it's not about the WDT?

could also be something unrelated corrupting memory so there is swdt? hostByName works-for-me at least standalone, esp_delay callback returning true as well
not necessarily, but might be an easier answer. corrupting something, forgeting to initialize stuff... also notice esp8266/Arduino#8393 update that fixes compiler bug with -Os
having noticed some c-specific flags in platform.txt and lwip builds... why is .c set to have -fno-inline-functions?
why is .c set to have -fno-inline-functions?
I think it is historical and probably meant to save space back then.
We could remove it but the effect will be little since all
.c files were converted to .cpp files quite a time ago.
true. I though that might do something when including local llhttp's .c files for parsing. zero difference between this option on or off
lwip & bearssl might need testing though
LWIP and BearSSL are built outside of the Arduino platform.txt so don't have this flag set anyway.
