Hello,
First of all, I'm delighted to have found the beginning of eMMC support for Nordic devices as software peripherals in NCS 3.2.0: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrfxlib/softperipheral/doc/sEMMC/README.html
As I understand it, this soft peripheral is still in the early stages of development. I have read through the features and the limitations of the driver, but because I am evaluating a new project, I need more information regarding the eMMC development roadmap.
For the nRF54LM20A, the frequency maxes out at 32 MHz. With no DDR and 4 data lanes, this comes out to a maximum possible data rate of 16 MB/s.
Are there any plans to increase this data rate in the future by including DDR support or expanding to 8 data lanes?
Also, are there or will there be samples available to implement sEMMC? To my knowledge, only the low-level driver currently exists.
Is there a plan to integrate it into Zephyr's disk access layer for easy FatFS/file system access?
Kind regards,
Daniel
