Setting up RT1064 to memory map Hyper RAM using the FlexSPI driver

kl — Mon, 19 Oct 2020 12:18:08 GMT

I am looking for som help setting up a HyperRAM on the RT1064. We need to set it up as memory mapped RAM.

It should be possible to setup the FLEXSPI to handle this allowing the firmware to acces the RAM from address 0x60000000. I have found an application note for the RT1050 (AN12239) which describes this. But I cannot find the example (hyper_ram.zip). We are developing a custom board with a APS6408L 64Mb RAM. Further more is there any instructions how to configure the driver by using the MCUXpresso Config Tool?

Anyone having some clues?

Hello @kl,

You can find the software mention in the app note in the following link.

In the MCUXpresso Config Tools User's Guide (link) Chapter 6 mentions the device configuration tool that helps to configure the DCD. Also, I will suggest checking the SDK examples, this has a default configuration that you could check.

Best Regards,

Alexis Andalon
