how to debug a new board designed by myself?

[quandguo]

I designed a new board based on  "sabrelite", but I can not run any programs by usb. can Someone help me? the Debug information is as follows:

F:\tftpboot>sb_loader.exe -f sdk_unit_test_ALL.bin

Executed plugin successfully.

Succeed to download sdk_unit_test_ALL.bin to the device.

  Failed to run plugin sdk_unit_test_ALL.bin to the device.

F:\tftpboot>sb_loader.exe -f sdk_unit_test_ALL.bin

Failed to initialize memory!

  Failed to run plugin sdk_unit_test_ALL.bin to the device.

several questions.

- the logs are the result of running this same command twice?

- are you sure sb_loader.exe is suitable to run on your board? is the format of 'sdk_unit_test_ALL.bin' correct?

- what do you mean by debug a new board? already boot up or just attempt to boot up?

  Have you modified the normal things like ddr script, etc?

Does your board connects to PC via USB OTG? (Can you see a new HID-compliant device coming up?) Or you dont have the USB OTG option on your board?

Have a nice day,
