Part Number: TMS320F28379D Tool/software: Hi Champs, I am trying to log some data from a LAUNCHXL-F28P65 to a SD card ( https://www.reichelt.de/de/de/shop/produkt/entwicklerboards_-_breakout-board_fuer_microsd-karten-266045 ). I program the microcontroller via Simulink following these two examples: * https://de.mathworks.com/help/ti-c2000/ug/prerequisite.html * https://de.mathworks.com/help/ti-c2000/ug/mat-file-sd-card-logging.html However after running the program the SD card is still empty. As hardware setup I connected the GPIO pins as depicted in https://www.ti.com/lit/ml/spaz022/spaz022.pdf?ts=1742373262159&ref_url=https%253A%252F%252Fwww.ti.com%252Ftool%252FLAUNCHXL-F28P65X to use SPI A as connection. I configured try to run this simulink example and checked as well the setting of hardware parameters three times ( https://de.mathworks.com/help/ti-c2000/ug/mat-file-sd-card-logging.html ). Besides I tested with a logic analyzer, that the pins only display idle line while running the program. When using the "SPI transmit" block of the C2000 library I receive the "correct" clock and values on the "PICO / MOSI" line. However, that wont write to the SD card. Why is the logging using the "Scope", "Outport" or "To Workspace" block not working? What could I change? Thank you in advance for your help! Cheers, Isabella
