4. Cpu_unaligned_wr

4.1. Function description:

The demo is that SDIOn writes data to EMMC and then reads data from it via cpu 8-line mode.

4.2. Test result:

If the data of SDIOn received is equal to SDIOn transmitted, print pass, if not print fail.

4.3. IO connection:

PAD	PAD
pad_sdion_sdclk	emmc_clk
pad_sdion_sdcmd	emmc_cmd
pad_sdion_sddat0	emmc_dat0
pad_sdion_sddat1	emmc_dat1
pad_sdion_sddat2	emmc_dat2
pad_sdion_sddat3	emmc_dat3
pad_sdion_sddat4	emmc_dat4
pad_sdion_sddat5	emmc_dat5
pad_sdion_sddat6	emmc_dat6
pad_sdion_sddat7	emmc_dat7

Note

• The ‘n’ in “sdion” indicate the peripheral number.

• The data sent and received is not 4-byte aligned.
