Description
Rock 4C+ image experienced instability during boot due to the bootloader initializing with an incorrect memory clock of 800MHz, instead of the maximum supported 666MHz.
This update incorporates a newer version of U-Boot that includes a default configuration for the 4C+ and specifies binaries for DDR and BL31.
How Has This Been Tested?
