Does the LPDDR4 matching IMX8MNANO have to be single 16bits*1channel?

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.

but K4F6E3S4HM shows Dual channel per die device

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