Hello everyone I am trying to write to SDCARD with FATFS. Data received from BLE and SAADC incoming data. Writes every second. The size is about 100 bytes. SAADC is 1000 samples per second. When BLE communication is stopped, normal data is written. When you start BLE communication, the data will collapse. I changed the interrupt priority order of SPI or clock frequency, but there is no change. Please give me a professor if you have any hints.
