Hi Cicero,

Without your changes "forcing rf_cal to sane values in the code" I was getting the rf_cal[0]!=0x05 error.
After your changes, I kinda get started - but the moment there is anything to do with the WiFi, the device crashes out. Which tells me the defaults you have given don't work for me.

Has there been a proper fix for this? or what am I missing?

I was away from ESP development for a long time and my code/environment would not work due to "msys-xxxx.dll" in MinGW installation. So I upgrated to UDK from CHERTS v2.2.2 (23.04.2017)

I am using the ESP-01 module with BQ25Q80ASSIG (Berg Micro 8Mb as per http://www.datasheetcafe.com/25q80assig-datasheet-flash-memory/ )

When you say the device crashes out, what does it print?

I have attached the "blinky" project from the examples of UDK with the user_rf_pre_init() changes you recommended, which also crashes like the project that I am working on... We can use this project like a lab rat

- Wed Nov 28, 2018 12:50 am #79309 One thing I missed in this whole new upgrade to new UDK was not doing "flash_init". I think due to the rf_cal change from Espressif, it warrants this step to init the flash with the default values.

When I did this, and also removed the fix from Cicero I dont get the "rf_cal" error any more.
But I get a Fatal exception 0(IllegalInstructionCause): - now this is a different problem.

Thanks for the help.
