so your guess is that the SPI transaction failes very very infrequent due to too high of a clock rate or internal problems? I'll try a reduced clock rate. I...

A thx. Code 1 - Reset Failed is understandable Code 17 - Activate card initialization doesn't mean much to me. I just looked into my Sd card code. I mount...

Is the WiFi connected over SPI on the ESP32 ? Could this then be fixed by using the second SPI Port? Is hard to find information in this

Okay that is interesting. Thanks for finding the details! As I'm working with PlatformIO, I'll have to wait for a new firmware release for the espressif core. I'll report back...

no im using SPI_DRIVER_SELECT 0 and SHARED_SPI. But i'm currently not using any other slaves on SPI Dedicated means the SPI can not be used for other slaves right ?

The Logging ran through the night and is now at 16h with no write errors. Seems like switching to 10Mhz fixed the issue for now. I'll let it run to...

I'll try to reproduce this with my oscii tomorrow but I'm afraid that this will be too high of a frequency for mine. I'll report back the results. The Experiment...

> Array transfer, USE_SPI_ARRAY_TRANSFER 1, only applies when using the standard driver, SPI_DRIVER_SELECT 1. Unfortunately the Arduino standard call requires copying data to a temp buffer on transmit and filing...

Ah okay, i think i start to understand how the SPI communication works. I really like how versatile the SdFat lib is built with many options to adjust to different...

Second Run ran for 19h before crashing. My Monitoring Script crashed as well, so I'm not 100% sure it was not due to something restarting on the serial port. So...
