Does the LPDDR4 matching IMX8MNANO have to be single 16bits*1channel? We found that DDR trainning is failed when we use the LPDDR4 with 16bits*2 channels.

We can not change the number of channels when the Bus Width selected to 16 while using the excel,but the LPDDR4 we used has 2 channels.

Can you give some advices to fill the device information according to the following datasheet ?

device configuration with 1 channel like following can be used by i.MX8MN.

It is very common knowledge not the i.MX8MN special, you can check  with your hardware engineer.
