ok found the problem.
I was trying to use the nvs functions too fast before they had time to initialize (facepalm), so I set the same delay right after them
Thanks a lot!

Re: Flash write/read issue
Thanks ESP_adokitkat.
It worked with a delay 900ms not less ! The volatile didn't do anything.
There's clearly something very wrong here. I don't suppose I need to wait 900ms before I call my function!

Re: Flash write/read issue
No, the code executes once before the main loop. I realized I have this problem only in the first flash of the ESP. If I reset it works ok. The following is between resets. This is repeating which is ok Screenshot_1.jpg Screenshot_2.jpg Ofc this is not solving my problem cause it's the first flash t...

Flash write/read issue
Hi, I have been banging my head over the following. I have setup some functions to read and write to Flash which seem to work fine. But when I try to check the values of a global variable in flash compared to another global variable in RAM I have a problem. Before I even set the flash variable it is...

1-Wire example problem
Hi, I'm trying to setup a DS18B20 thermometer and use the 1Wire library from here https://github.com/espressif/esp-idf/tree/c460e1c/examples/peripherals/rmt/onewire My hardware setup is with a pull-up 4k7 like it suggests and I assume it's ok. I can't read the thermometer, I get the errors E (77649)...

Re: How to detect ESP restart from upgrade
Yes I have thought of that, but I was looking for something non-user dependent (during testing you don't change versions all the time). If there is no other way I will do it this way, I just thought that it should work this way For example ATMEL μCs have a register that defines the reason of a reset...

How to detect ESP restart from upgrade
Hi I'm trying to check whether the ESP has reset from an upgrade (USB or OTA) to reset my "reset_counter" variable which is stored in flash. I tried to detect that from the response from the function nvs_get(). If I get a "value not initialized" then it means I had a code upgrade and I should reset ...
