History: media_drv_mmcsd_stm32_v4x

This page describes all changes made to the media_drv_mmcsd_stm32_v4x package, the MMCSD Media Driver for STM32 V4.x, since its release.

Version

1.6 (2021-03-19, 12:55):

  • Bug fix: Mutex was not released by mmcsd_release() when there were active eMMC partitions accessed by the driver (MMCSD_ALLOW_EMMC_MANAGEMENT set).

1.5 (2021-03-02, 15:15):

  • MMCSD_NUM_UNITS moved to API, as the driver can only handle one unit and should not be configurable.

1.4 (2021-02-15, 15:45):

  • Added support for eMMC sleep/awake functionality, when getstatus is invoked the driver will wake-up the eMMC if it's in sleep mode.

1.3 (2020-10-16, 14:16):

  • Bug fix: Buffer overflow occurred for (e)MMC cards.
  • Frequency of SD/MMC clock was calculated wrongly for STM32F7xx MCUs.
  • mmcsd_initcard() could stick in endless loop when using 8 bit mode.

1.2 (2020-09-28, 15:00):

  • Bug fix: Read timeout was used for both read and write transfers.
  • Execute FIFO  Reset when error occurred during transfer.
  • Wrong FIFO status is checked at transferring data to card.

1.1 (2020-04-07, 18:30):

  • Initial release.
