Apologize in advance for a more rambling post than usual. Just finished one project and thinking about options for the next. I need to do some more research and hoping to jump start my lack of knowledge from the minds here. Lately, I find that for a lot of my projects involving Teensy that I am using a Linux SBC only for logging data and nothing else. In other words, I typically have a Teensy collecting sensor data and doing estimation / math and then sending data to an SBC just to log to its EMMC storage. Seems like overkill for what I am using it for and the SBC takes up a lot of space on my boards. I could log data to an SD card, but a lot of these projects are meant to be high reliability in high vibration and temperature environments and, maybe my opinion is unfounded, but I don't trust SD cards for those scenarios. Flash is easy, but I need more storage than I could feasibly do with it.
What would be the easiest / fastest path to large storage options that are permanent on a PCB? Is it possible to use the MK66FX1M0 SDIO lines (PTE0 through PTE5)to interface with EMMC? I notice the i.MXRT1050 chip has NAND and EMMC support, but my assumption is that this would take a lot of work to bring up. Are there controllers to interface with NAND or EMMC that simplify connecting to a microcontroller?
Thanks!
