大家好,我公司在用MCIMX6X4EVM10AB 做一个项目。现在遇到了板子不启动的问题,现象如下:

供电都正常,但是无论配置到qspi1  启动还是 SD2 启动,用示波器都测量CLK都没有信号输出,实在找不到原因,下面是我的原理图,请大神帮忙指点一下。

您好,

很高兴收到您的回复。

我现在把JTAG_MOD ,接地了。boot_mode0选为1 boot_mode1选为0,通过USB_OTG1连接PC,但是boot utility始终是这样的界面。

还有一个现象,我这边上电后,板子虽然没有启动,但是电流始终是 5V-120ma,这样的现象是否正常呢?

Hello,

 

  really glad to receive your response.

 

  I am now grounding JTAG_MOD. Boot_mode0 is selected as 1 boot_mode1 is selected as 0, and the PC is connected via USB_OTG1, but the boot utility is always such an interface.

 

  There is also a phenomenon. Although I have not started the board after power-on, the current is always 5V-120ma. Is this normal?

Hello,

   Looks like the i.MX6SX does not start at all.

Use recommendations of Chapter 4 (Avoiding Board Bring-up Problems)

in the i.MX6SX Hardware Development Guide.

hi,

有个问题想和您确认一下,PMIC芯片的LICELL引脚我目前是悬空状态,这样会有问题吗?这个地方一定要接一个纽扣电池吗?

Have a question to confirm with you, the LICELL pin of the PMIC chip I am currently floating, so there will be problems? Must I pick up a button battery in this place?

Hello,

  A capacitor to ground on the LICELL must be present. 

Regards,

Yuri.

Hello,     I am still not booting properly here. I will use the MfgTool2 software to download the firmware via USB_OTG to the interface ""loading U-boot". What is this because of this?

Hi,

  According to the screenshot the i.MX6SX starts in serial downloader mode. 

Try using other boot mode / devices.

Regards,

Yuri.
