Unable to complete DDR test via NXP DDR Tool in IMX8M Plus

Hi,

I downloaded RPA Tool and updated the information. Here is the snapshot attached.

VDevrari_1-1782305197778.png 

With the script I was able to get the PMIC information in debug.

here are the debug log and .ds file for reference.

I found out in the debug log the memory capacity was shown as :

Density per chip select:  4096MB 

Density per controller is: 4096MB 

but I have used LPDDR4 RAM with 1GB capacity (W66DP2RQQAGJ: Dual-Die-Package (DDP) 32Mb x 16DQ x 8-banks x 2 channels with 8 Gb (8,589,934,592 bits) density.

Also it got stuck in "Step 1: DDRPHY Training"

Hello,

I do not see issues in your configuration for that memory.

Do you get the same issue if you try with DDR Tool of Config Tools?

Best regards.

Hello,

The issue you are getting in Config Tools shows that there is an issue with serial port connection, please confirm that is connected to the Cortex-A console and the board in serial download mode.

Could you please share you schematic?

Best regards.

Hi,

The issue is resolved using MSCALE_DDR_TOOL.

Here is the link of the page for IMX8MP
