We are currently attempting to configure an LPDDR2-chip (ISSI IS43LD16640A).

 

Seing as we currently work on a Linux host system, we have attempted to do the config manually, taking inspiration from the following threads:

 

VF5xx / Example of LPDDR2 Configuration

Re: Executing from LPDDR2

Vybrid LPDDR2 Init

Vybrid LPDDR2 Configuration

 

The threads mention errors in the reference manual and internal correspondence, and does not seem to give the answer that we are looking for.

 

After a few failed tries, we decided that we could use Processor Expert to help us configure the LPDDR2-chips. This too was unsuccessful.

 

This is very hard to debug, and pinpointing single issues is next to impossible. Are there any resources, other than the Processor Expert Validation Tool, that may help us in this process? Are there any helpful people out there who knows configure this chip?
