History: media_drv_mmcsd_synopsys


This page describes all changes made to the media_drv_mmcsd_synopsys package, the MMC/SD Media Driver for Synopsys, since its release.

Version

1.8 (2020-02-19, 10:58):

  • Added High Speed (maximum 50Mhz) support for SD cards.

1.7 (2019-11-22, 16:30):

  • Access failures could occur with some SD card variants, though rarely.

1.6 (2018-09-13, 16:31):

  • Reinitializing the driver after uninitializing it might cause the driver to hang. (Use case: mounting, unmounting, then mounting a file system volume again.)
  • Card removal during data transfer (reading from or writing to the card) could cause the driver to hang.

1.5 (2018-09-12, 16:04):

  • Module renamed to media_drv_mmcsd_synopsys as the driver is not only suitable for the NXP LPC43xx series but also for the NXP LPC314x series and for the Analog Devices ADSP-SC58x family. The MMC/SD core has been designed by Synopsys hence the name.
  • ADSP-SC58x support added.

1.4r2 (2018-08-29, 18:25):

  • Document HTML link added to the documentation folder.
  • History and document files renamed to the package name.

1.4 (2018-04-05, 11:37):

  • Adapted to common MMCSD init module (media_drv_mmcsd_init).
  • General PSP references' cleanup: driver expects standard HCC MMCSD-PSP function names now (starting with "psp_").

1.3:

  • Card initialization might have failed to finish with some cards.

1.2:

  • Operation fixed in cached environment.

1.1:

  • Warnings (possible use of uninitialized variables) removed.

1.0:

  • Initial revision.
