你好；

你在系统起来后，通过 dvr_rdk/ti816x/bin/mem_rdwr.out 去对一下 pinmux 的寄存器，看都配置对了吗？

寄存器地址在datasheet 中的 4.5.1 PINCTRLx Register Descriptions 章节可查到

ternence hsu,

我用./mem_rdwr.out --rd xxx的方式去读，发现配置的寄存器值并不是我在kernel里面pinmux设置的值，然后直接通过./mem_rdwr.out --wr xxx

的方式去写，发现写不进去。然后通过修改pCaptureInstPrm->videoCaptureMode = SYSTEM_CAPT_VIDEO_CAPTURE_MODE_SINGLE_CH_NON_MUX_EMBEDDED_SYNC;里面pCaptureInstPrm->videoCaptureMode 这个值，可能会影响到pinmux寄存器的值，但是又和datasheet上的对应不上。

例如：在SYSTEM_CAPT_VIDEO_CAPTURE_MODE_SINGLE_CH_NON_MUX_EMBEDDED_SYNC时候

测试vin1_portb sync signal name value

./mem_rdwr.out --rd 4814094C 1 VIN[0]B_CLK 0x00

测试vin0_porta sync signal name value

./mem_rdwr.out --rd 48140948 1 VIN[0]A_CLK 0x00

//=============这些是我想要的值，按照道理来说。

结果却是：

你是用的什么版本的SDK ？

在uboot 、kernel 和 hdvpss （M3）中中都可以修改pinmux

你查看一下

DVRRDK_04.00.00.03/ti_tools/hdvpss/dvr_rdk_hdvpss/packages/ti/psp/platforms/ti816x/src/vps_platformTI816x.c

static Int32 Vps_platformTI816xSetPinMux(void)

可以屏蔽，或者修改，试试；

先屏蔽一下，再打印寄存器的值，看是否正确了。

REG32(CSL_TI816x_CTRL_MODULE_BASE + 0x0868) = 3/*1*/;   //26 tsi5_data     vout0_b_cb_c0   vout1_b_cb_c9   vin1_hsync1
REG32(CSL_TI816x_CTRL_MODULE_BASE + 0x086c) = 1;   //27 tsi5_bytstrt vout0_b_cb_c1   vout1_hsync     vout1_avid

代码如上修改了，但是结果如下

root@ti81xx:/opt/dvr_rdk/ti816x_2.8/bin# ./mem_rdwr.out --rd 48140868 4

0x48140868: 00000003
0x4814086c: 00000002
0x48140870: 00000002
0x48140874: 00000003

还有别的地方会影响到 0x4814086c 这个寄存器的值吗？

Koo Gun,

Pinmux寄存器在A8侧必须是A8处于supervisor模式才能修改，所以mem_rdwr.out是写不进去的。

请参考下面的链接，看你第一个帖子添加的配置代码的位置是否正确？

Chris Meng,

一，kernel

我在kernel里面的omap/devices.c设置了如下：

#if 0

omap_mux_init_signal("vin1_vsync1", OMAP_MUX_MODE3);
omap_mux_init_signal("vin1_hsync1", OMAP_MUX_MODE3);
omap_mux_init_signal("vin1_fld1", OMAP_MUX_MODE3);

#else

__raw_writel(0x3, 0x48140868);//HS
__raw_writel(0x3, 0x48140870);//VS
__raw_writel(0x3, 0x48140874);//DE

#endif

这不能改变0x48140868，0x48140870，0x48140874这三个寄存器的值

二，PSP

然后，我按照ternence_hsu讲的改了DVRRDK_04.00.00.03/ti_tools/hdvpss/dvr_rdk_hdvpss/packages/ti/psp/platforms/ti816x/src/vps_platformTI816x.c

这里面的值，然后烧进板子，发现可以改变0x48140868，0x48140874这两个寄存器的值了，但是0x48140870的值还是不能改变。

三，uboot

在uboot里面的 Cmd_logo_816x.c 的 SetDvo2PinMux()函数

/*set the HSYNC/VSYNC for HDCOMP, use DVO1 signal, this
   is for PG2.0 or above silicon only*/
   if ( get_cpu_rev() >= PG2_0) {
       /*these settings matches DVR reference,
       it may not work with DM816X EVM*/
       #if 0   //modify by kg-three 20160818
       WR_MEM_32(0x4814086c, 0x2);
       WR_MEM_32(0x48140870, 0x2);
       WR_MEM_32(0x48140724, 0x2);
       #else
       WR_MEM_32(0x4814086c, 0x2);
       WR_MEM_32(0x48140870, 0x3/*0x2*/);
       WR_MEM_32(0x48140724, 0x2);
       #endif
   }

也是不能改变寄存器的值的。

我感觉还是有哪些控制着0x48140870这个寄存器。
