I can't get the SDMMC working with DMA on the STM32L4A6ZG, so I'm looking for alternatives. I've already started down the path with the NUCLEO-144, so I'd prefer something that I can get on that. I've heard (from Tesla DeLorean) that "the L4 has at least 3 implementations, including different approaches to integrating DMA, and using 1 or 2 DMA channels." How can I pick a good one?
If I switch to, say, the STM32L496ZG, I'm guessing I'll get the same SDMMC. Right? How about something a little different, like the STM32L4R5ZI? Oh, but that one does not seem to be available. The STM32L4P5ZG looks promising, but again, not available.
I need something low power, with lots of I/Os, Cortex M4 with FPU, at least one SDIO or SDMMC (with DMA), at least 3 SPI and a couple of I2C. I don't need the Cryptography features of the STM32L4A6ZG.
