Hyperram Interface
#1
Hi all, 

I am new to the forum and like to say Hi to all. I've been looking into using Pulpissimo platform in one of my projects that I am currently working on and would like to ask for some help. At the moment, I am at the very early stage of the project. My intention is use to use very basic subset of the Pulpissimo platform so I would like to start by removing some things that I don't need.

Is there an easy way of removing Hyperram interface from the udma subsystem? I would potentially also want to remove Cam interface and I2S interface. My project will, most likely, be using SPI and SDIO interfaces as well as uart. 

Thanks. 

If there is already a thread addressing this topic, please refer. 

Best

Hello,

We get this question a lot. First suggestion is, do not modify things too much at the start. Even if you do not plan to use it, keeping it around makes life easier. That being said, hyperram, cam and I2S should not be a big deal to remove. However, do not remove the UDMA as it is sort of glues in everything.

It does not answer directly your questions, but there are a couple of videos under

That could help you with a lot of the problems.
