Difficulty with 1GB DDR3L memory routing and STM32MP151DAC1

[ariondoneda]

Hi,

I'm having some difficulty routing 1GB DDR3L memory with the STM32MP151DAC1. Both reference boards available for this product use different memory or pitch configurations. 

I found an Application Note, AN5122, that guides through memory routing, but I would like some actual reference design example, to compare. There are any reference, ap notes, or anything to help with this?

Regards,

Arion Doneda

Hi @ariondoneda ,

I guess you overlooked the following file which is provided together with AN5122
STM32MP15x Series DDR memory routing guidelines examples

you will find routing examples for STM32MP15 in 'AC' 12x12 package with one or two DDR3L x16.

Regard.
