Following the Rockchip RK3399TRM datasheet, I'm looking to change the value of register 0xFF77E014 to a specific value (GRF in Address Mapping, offset 0xE014).
What are the possible ways to write to these registers?Author: leung先森 Time: 11/30/2018 16:43
If in uboot , use below
+ writel(0x10001, 0xff770000 + 0xe640);
+ reg = readl(0xff770000 + 0xe640);
Copy the code
