DDR Clock-Rate

#1

For porting requests and questions about the compatibility of a certain device with atvXperience ROM, please perform the following test and add the current clock frequency value of your RAM to your request/question. Please specify the exact RAM memory type - DDR3/4, LPDDR3/4 etc. (exact marking of the RAM chip is required).

You can find the DDR Clk. Rate in the following ways:

Code: Select all

adb connect <your_board_ip_addr>:5555
adb shell dd if=/dev/block/mmcblk0 of=/sdcard/ddr_clk.bin bs=1 count=2 skip=41482
adb shell hexdump -e '"%d"' /sdcard/ddr_clk.bin
a decimal value appears immediately before the shell_prompt, which is the current DDR clock rate in Mhz ..
In my case "744" Mhz

The commands should be done with original ROM.
