Don't worry, everybody want's their issues solved :) I have now made another test that regulary writes and downloads from MicroSD with 20000 kHz on another device with another MicroSD and it does not crash so far so I think it is related to printing so much. All other devices are running fine so far...

Thank you for following up! I am testing currently with the ESP-IDF master because I need WPA2 enterprise fixes (I don't think they are included in a release so far). @igrr: Heap poisoning is already set to comprehensive. I actually think this issue is because of verbose logging. Now that we have se...

Mutexing did unfortunately not solve the issue, also doubling the esphttpd task stack size did not help

I will definitely look into the stack but I monitor the min free and so far was no problem. I have now added mutexed access to whole SPI, le'ts see if that helps. The MicroSD is SDSDQAF3-008G-XI (https://eu.mouser.com/ProductDetail/SanDisk/SDSDQAF3-008G-XI?qs=%2fha2pyFadujUtus0E1o28yG0bLrh8QryCGvAIK...

Thank you very much for following up with this. I was actually able to capture the issue over night. I also tried removing the MicroSD while the electronic is powered and doing a soft reset with esp_restart() which makes the system work again. This happens immediately before it stops working: V (170...

I will try but the error sometimes happens after days and most devices are not accessible, only a small test setup on my desk. As the other devices are in "the field" the question stands if it could be helpful to set the pins to gpio first and turn them low or something in that regard.

Hi, I've got a little problem and maybe someone of you has more experience working with MicroSD cards. I'm initializing the MicroSD like this: #define DEVICE_MICROSD_MISO GPIO_NUM_26; #define DEVICE_MICROSD_MOSI GPIO_NUM_25; #define DEVICE_MICROSD_SCK GPIO_NUM_33; #define DEVICE_MICROSD_CS GPIO_NUM_...

This pull request solves my issue and I can connect to my WPA2 Enterprise network now https://github.com/espressif/esp-idf/pull/2354

Hi RavenHawk, this is what I am planning too, what you will need is a wifi interface that supports monitor mode and then use Wireshark for capturing. Kali Linux is a good point to start.

Edit: I've ordereed a Alfa Network AWUS036NHA because of it's monitor mode and injection capabilities

Hello, In my case my university uses "eduroam" WPA2 Enterprise, TTLS, no certificate, MSCHAPv2(no EAP) and I was able to connect using the code below. I had to insert the WiFi.mode(WIFI_STA); otherwise my ESP32 would reset with Guru meditation.. Hello Fabio, unfortunately this does not work for me ...
