Stack Overflow on First Boot - ESP-01

[KWolfe81]

I am new to to the ESPEasy. I just downloaded the binary onto an ESP-01 (black ESP8266 boards) and am getting an flash write errors and what appear to me as stack pointer overflows. I tried this on two different chips - same result. I'm using the normal build - 1024 and tried both the 8/9/2018 and 7/16/2018 release w/ same results.

Your flash bin is for 1MB devices. According to the table found in the link below (bottom of page), there's only 512K memory on the ESP-01:

My understanding is that the black PCB ESP-01 modules are 1MB devices:

https://www.esp8266.com/viewtopic.php?f=13&t=13659
https://www.amazon.com/ESP8266-ESP-01-S ... B012YW5BE6

I wonder if that's true though.

[ThomasB]

They can come in a variety of memory size, but 512K is typical. The black version seems to advertise 1MB, but some vendors are clueless on what they are selling. Try the memory check program seen here:

Digging, I found this thread to be relevant:

https://github.com/letscontrolit/ESPEasy/issues/650

Specifically.:

From the ESP-easy site: At this time ESP-01S are sold with a flash chip marked "PUYA". These flash chips have a problem with using SPIFFS memory and do not work with ESP Easy. The problem is under investigation. At this time there is no given solution besides using other ESP-01 if available or changing the flash chip on the ESP-01S. UPDATE: A fix seems to be on the horizon. Stay tuned!

And this:

https://github.com/esp8266/Arduino/issues/4061

[KWolfe81]

It's great being late to the party, other people have already solved your problems. The precompiled PUYA version and included with the releases solved the problem.

[ThomasB]

Glad to hear it's working. Thanks for the PUYA info.

There were two different Arduino Esp.cpp patches in the gihub discussion that fix the PUYA issue. I flipped a coin and installed this one:
https://github.com/esp8266/Arduino/file ... uya_v2.zip

I read that @TD-er is working on integrating it into the compiler releases so that a special PUYA branch can be avoided. But for now the files tag with PUYA must be used.
