RK3588 DDR变频介绍
RK3588 DDR支持4频点的变频，4个频点如下：
rk3588_s_evb2:/ $ cat /d/opp/opp_summary
device rate(Hz) target(uV) min(uV) max(uV)
-------------------------------------------------------------------
platform-dmc
528000000 850000 850000 850000
1068000000 850000 850000 850000
1560000000 850000 850000 850000
2112000000 850000 850000 850000
这四个频点是由ddr的loader决定，kernel变频的时候使用的是档位值分别是：
- DMC_FREQ_LEVEL_HIGH //最高频率(2112MHz)
- DMC_FREQ_LEVEL_MID_HIGH //第二档(1560MHz)
- DMC_FREQ_LEVEL_MID_LOW //第三档(1068MHz)
- DMC_FREQ_LEVEL_LOW //最低频率(528MHz)
由于硬件设计和走线的差异已经ddr颗粒差异导致有些板子无法跑这么高的频率，导致系统不稳定，就需要修改DDR的最高频率和其他频点。
DDR参数修改工具ddrbin_tool
ddrbin_tool在SDK的路径
rkbin/tools/ddrbin_tool
ddrbin_tool的使用方法
@sys2_206:~/3_Android12_29_debug/rkbin/tools$ ./ddrbin_tool
version v1.09 20211130
For more details, please refer to the ddrbin_tool_user_guide.txt
This tools support two functions
for example:
fun 1: modify ddr.bin file from ddrbin_param.txt.
./ddrbin_tool ddrbin_param.txt px30_ddr_333MHz_v1.15.bin
fun 2: get ddr.bin file config to gen_param.txt file
./ddrbin_tool -g gen_param.txt px30_ddr_333MHz_v1.15.bin
The 'V1.11' as follow means the minimum ddr.bin version requirements

导出ddr参数信息
@sys2_206:~/3_Android12_29_debug/rkbin/tools$ ./ddrbin_tool -g gen_param.txt ../bin/rk35/rk3588_ddr_lp4_2112MHz_lp5_2736MHz_v1.07.bin
version v1.09 20211130
version 2
generate info from bin file ok.
导出的信息保存到当前目录的gen_param.txt 文件中
修改DDR的参数
- 修改的ddrbin_param.txt文件，这个文件里面的参数默认都是空的，只要修改自己需要的参数就可以。该文件在
rkbin/tools/ddrbin_param.txt文件的具体参数说明可以参考文档rkbin/tools/ddrbin_tool_user_guide.txt - 使用ddrbin_tool导入修改后的ddrbin_param.txt来更新ddr bin文件
@sys2_206:~/3_Android12_29_debug/rkbin/tools$ ./ddrbin_tool ddrbin_param.txt ../bin/rk35/rk3588_ddr_lp4_2112MHz_lp5_2736MHz_v1.07.bin
version v1.09 20211130
version 2
new bin config:
modify end
- 修改成功后，将生产的…/bin/rk35/rk3588_ddr_lp4_2112MHz_lp5_2736MHz_v1.07.bin 编译到loader中烧写到机器里面即可。
下面介绍如何用ddrbin_tool 修改ddr频率
- DDR 最高频率修改
- 编辑ddrbin_param.txt中的如下参数，先确认使用的DDR的类型

* UART info
uart id: uart number. 0 for uart0, 1 for uart1, 2 for uart2..., 0xf will disable uart.
uart iomux: uart iomux info, 0 for uartn_m0, 1 for uartn_m1, 2 for uartn_m2...(like uart2_m0, uart2_m1,uart2_m2),
or 1 for uartn_a, 2 for uartn_b, 3 for uartn_c.(like uar2a, uart2b, uart2c).
uart baudrate: uart baudrate should be 115200 or 1500000.
- 编辑ddrbin_param.txt中的如下参数
下面实例是修改debug串口为uart2 的uart2_m1口。波特率是1500000

- 修改后按上面介绍的步骤重新生产ddr bin文件，替换到原路径的ddr bin文件，ddr bin文件的路径可以通过如下文件确认：
其中：Path1=bin/rk35/rk3588_ddr_lp4_2112MHz_lp5_2736MHz_v1.07.bin就是ddr bin的文件路径，替换改文件即可。

以上修改完需要在u-boot下面重新编译uboot，然后烧写u-boot下生成的rk3588_spl_loader_v_xxx.bin， 如果是build.sh完整编译则可以烧写rockdev下的MiniLoaderAll.bin
-
如果要关掉loader阶段的串口打印，只要将uart id设置为0xf即可
