  • RTOS/CC2640R2F: SDSPI task causes BLE to disconnect in simple_peripheral

    TI Thinks Resolved
    Part Number: CC2640R2F Tool/software: TI-RTOS I am trying to write data to an SD card while maintaining a BLE connection. I successfully wrote an implementation of the SDSPI driver for the cc2640r2f launchpad. From this, I learned that the SD card…

  • SDSPI does not support cc26xx

    Hello, Reply to my post, https://e2e.ti.com/support/embedded/tirtos/f/355/t/461715 one and half year ago, I have done SD_CARD read/write and all file operation for CC26xx. But unfortunately I lost the driver code. Now, again I am going to write…

  • RTOS/LAUNCHXL-CC2650: SD FATFS - SDSPI driver

    Part Number: LAUNCHXL-CC2650 Tool/software: TI-RTOS Hello, I have tried to build the FAT FS for a sd card with CC2650 and the Code Composer Studio. I have built the SDSPICC26XX driver which is the "bridge" between the SDSPI driver and the SD FATFS.…

  • RTOS/CC2640: Writing with SDSPI interface waits 34us for every byte?

    Resolved
    Part Number: CC2640 Tool/software: TI-RTOS Hello experts, I've implemented a SD SPI interface a while back ago that based on TI SPI driver. I hook the ported driver with FATFS so I can write, sync and close the text file in a readable format. Not…

  • RTOS/LAUNCHXL-CC2650: CC2650: SDSPI cannot write/read raw data to SD card

    Part Number: LAUNCHXL-CC2650 Tool/software: TI-RTOS I've implemented a SDSPICS26xx driver based on SDSPITIVA to connect SPI driver and the SD FATFS. My program can mount the SD card and "request" SPI communication (SD_Spi_open, SD,chipSelect, SD_chipDeselect…

    Resolved
    Part Number: CC2640R2F Other Parts Discussed in Thread: CC2640 Tool/software: TI-RTOS Part 1: The older Simplelink_cc2640r2_sdk_1_x_xx_xx (versions 1.4 and 1.5) did not support the SDFatFS driver for the cc2640r2f. I wrote an implementation…

    Resolved
    Part Number: CC2640R2F Hello, I am working with a custom board and trying to program the SPI peripheral as a master to read from an SD card. I can see that the driver initializes successfully with some cards at 400k but not ith others. I wish to reduce…

  • RE: RTOS/CC2650: LAUNCHXL-CC2650

    Hi, you are right. The SDSPI driver for both the MSP432 and the CC32XX build upon driverlib, the low-level hardware abstraction layer and implement SPI functionality on their own instead of using the high-level SPI driver. I do not know whether the…

  • RE: CCS/LAUNCHXL-CC26X2R1: SPI for SD card file system

    Please take a look at the sdspi documentation: If you want to debug/step throug the code to be able to figure out what is going on, you need to manually include the driver files in your project. BR Siri
