TI中文支持网我的DM368主频为297Mhz，DDR为243Mhz。
我有根据 http://processors.wiki.ti.com/index.php/DM36x_to_DM368_NAND_UBL_porting_guide更改ubl源码
我的烧写方法为sfh_DM36x.ext. windows下烧写
我的ubl源码未改之前是OK的。
结果为：

可以看出，主频为297Mhz的时候都是可以的，DDR可为270MHZ ,243Mhz. 当主频为432MhZ的时候，系统就起不来了。
请问这是什么问题造成的？？？
JUKE CHEN：
可否有人回复我一下。
Chris Meng：
回复 JUKE CHEN:
Juke，
请问你使用的DDR芯片和TI EVM上是完全一样的型号么？如果不是，DDR的参数是否有根据你用的DDR芯片做过调整？请参考：
【TI FAE 分享】TI DM36x DDR2 寄存器配置表http://www.deyisupport.com/question_answer/dsp_arm/davinci_digital_media_processors/f/39/t/69143.aspx
JUKE CHEN：
回复 Chris Meng:
Chris Meng，
是的DDR芯片是完全一样的，我们的设计是参考官方的原理图的。
我找到了问题的原因，因为CVDD这个 ARM内核电源电压，我们的是1.2v的，可是手册上推荐的是1.35v。
我查了，相关的资料。应该是只有电压为1.35v时候，才能达到主频432Mhz。
JUKE CHEN：
回复 Chris Meng:
我现在有一个问题。
我用得电源管理芯片是TVP65023RSB，这个芯片该如何配置，使其生成1.35v呢？
我有看芯片手册。
问题是：我用查看 root@dm368-evm:/sys/devices/platform/i2c_davinci.1/i2c-1，没有找到其i2c的设备。
但是我使用i2c工具 ，可以看到0x48
The TPS65023 has a 7-bit address: 1001000, other addresses are available upon contact with the factory
则 tps64023的设备地址应为0x48 ,说明有这个I2C设备的。
root@dm368-evm:~# i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f00: — — — — — 08 — — — — — — — 10: — — — — — — — — — — — UU — — — — 20: — — — — — — — — — — — — — — — — 30: — — — — — — — — — — — — — — — — 40: — — — — — — — — 48 — — — — — — — 50: — — — — — — — — — — — — — UU — — 60: — — — — — — — — UU — — — — — — — 70: — — — UU — — — —
我又查看寄存器读取。说明我的却是是1.2v
root@dm368-evm:~# i2cget -y 1 0x48 0x06 0x10root@dm368-evm:~#
我想改为1.35v 我是用
root@dm368-evm:~# i2cset -y 1 0x48 0x06 0x16root@dm368-evm:~# i2cget -y 1 0x48 0x060x16
但是只要板卡重启就恢复为0x10了。
问题还是，这个TVP65023该怎么配置呢？
Chris Meng：
回复 JUKE CHEN:
Juke,
电源电压的修改应该是在上电后马上修改，你是否有看过u-boot里面的相关代码？
JUKE CHEN：
回复 Chris Meng:
我们之前的的uboot，没怎么改过的。 所以对这方面不太了解。
请问uboot里是怎么控制电源芯片，调整电压的呢？
lu edward：
回复 JUKE CHEN:
你是不是也在dm368的群里?
