Hi Everyone. I'm collecting information to get even faster boot times, I have 2 questions. It is written that it is possible to boot from MMC (8bit mode) (18.1.1 MMCHS Features) using MMC mode with TRM of am335x. - Clock support -96-MHz functional clock source input -up to 384Mbit/sec (48MByte/sec) in MMC mode 8-bit data transfer -up to 192Mbit/sec (24MByte/sec) in High-Speed SD mode 4-bit data transfer -up to 24Mbit/sec (3MByte/sec) in Default SD mode 1-bit data transfer
Also, the SD_CON register DW8 Field has a flag for it. I expect this setting to start up much faster. In BBB, how do I set it to 8bit mode and how do I set the frequency to 384Mbit / sec (is it mmc_clk/clock-div in Devicetree?)?
