i.mx6q-sdb board emmc boot up

[carmilili]

I have a question about boot up from eMMC.My board is i.mx6q-sdb.

I burn  uboot image and file system to the eMMC by MfgTool successful.Boot switch SW6  set to be 8'b01101011(7-0).

When I restart the board,but it can not boot up.Why?When I the click 'Start' on the MfgTool,it boot up and enter the linux filesystem.

The MfgTool do not burn three files again.

1:Why the boart can not boot up automatic?What do I need to set?

2:How can I burn uboot image and file system to the eMMC again?

Hi Carmili,

When you want to download uboot image and file system by MFGTool to eMMC, you need to change the SW6 to 00110000(7-0) download mode. Downloading finished, you can change switch SW6  to 01101011(7-0) to boot the board from eMMC. Would you please try? Hope this can help you~~

Best Regards

Thank you for your reply.

I save the problem now.I use the Ubuntu minicom to receive message.It will interrupt the MfgTool  burn images to the eMMC.When I use the windows serial tools.It is OK.
