Ning Yang commented: https://gitlab.rtems.org/groups/rtems/-/epics/6#note_110643 Coding Period Week #13 Planned: - SD R/W access support. - mailbox driver Completed: 1. Merged SPI MR. !103 2. Improved Watchdog MR. rtems/rtos/rtems!120 3. Read freebsd-org/sys/arm/broadcom/bcm2835/bcm2835_sdhci.c. Blockers/Problems: 1. Barusu's mailbox driver is missing some implementations. I want to complete them after porting the SDHCI driver. In bcm2835_sdhci.c file, there are only two functions to communicate with mailbox: ```c bcm2835_mbox_set_power_state(BCM2835_MBOX_POWER_ID_EMMC,TRUE); bcm2835_mbox_get_clock_rate(BCM2835_MBOX_CLOCK_ID_EMMC,&default_freq); ``` There can be some alternatives - `bcm2835_mbox_set_power_state`: I can use a temporary function to communicate with the mailbox to set power state. - `bcm2835_mbox_get_clock_rate`: I can get the clock rate from the spec file. 2. sdhci uses dma mode for transmission. I need to complete the DMA driver first. Next week plans: 1.
