Finished Emmc Flash for Rockchip Soc , As the ddr4 is now finished i wanted to move on to the emmc flash , so i locked up the list of supported emmc parts but the list was from 2024 and had 2 model options for the RK3566 B/C but i had E??? So i was a little confused and began research but there was nothing so i scrapped the internet to find some newer list , eventually i found a updated one and there was a huge and i mean really huge list of tested emmc… I looked up wich ones are avaible on lcsc in my prefered GB size and picked one but after hooking up some connections i saw a problem , to use the H200 or H400 protocol speed like the rockchip wants VCCQ would need to be 1.8v but the datasheed meintion many times the chip can only work for 1 hour at a time then (also even finding the datasheet was hard) .. so i had to research and eventually found a better pick wich i hooked up and i changed the voltage config pins for the flash voltage on the rockchip addet some filters on the pwr lines and also hooked it up to the rockchip (not on the screenshot , other schem. page) .. there i addet the by the datasheet required parts and by the emmc datasheet …. also i addet a button to DAT0 , if this pin is connected to GND wich the button does when pressed the rockchip enters a failsafe mode .. this is a non brickable in soc safed mode that enables reflash/unbricking the soc over usb in case it happens (called Maskroom) …
