Describe the bug
E (748) vfs_fat_sdmmc: slot init failed (0x103).
E (749) sd.h: Failed to initialize the card (ESP_ERR_INVALID_STATE). If you do not have an SD card attached, please ignore this message. Make sure SD card lines have pull-up resistors in place.

According to the example 'sdspi' provided by esp-idf, I modified the code.
But I encountered a new problem. I can initialize and write a single file, but I cannot write the obtained CSI data into csv file.

Can you share the specific idea of obtaining CSI output to SD card in real time?

Another point that puzzles me is that when I set up to collect CSI only through the SD card, I still seem to be able to collect CSI from the serial port.
