We plan to design a stm32mp13x board equipped with 8MB psram using FMC interface as system RAM. It's going to be very slow but that's fine for our application, and standby power consumption is the topmost priority in this project. How should we deal ...

I just read this document : https://www.st.com/content/dam/specialevents-assets/dc22/pdf/room-3-1-stdevcon22-session-nfc-for-wireless-charging.pdfIn page 13, there are two daughter boards, one based on ST25R3916 (NFC reader) and the other based on ST...

I wonder whether I can connect two quad spi ap memory to the same octospi interface on stm32h730 to double the bandwidth. Or such a configuration can only be used with nor flash, not psram. Thanks.

I have a STM32MP157D-DK1 board. I downloaded design files and surprisingly found there were 56ohm series resistors on ddr address lines. Though series resistors are normally found on data and address lines for ddr1 or ddr2, I have never seen them use...

Thank you so much for your advice and confirmation. And yes, the RAM size is too small for a linux system. We are going to develop a bare-metal solution.

how to deal with DDR pins if DDR not used on STM32MP13x series

Any reference design for nfc wireless charging?

Could Dual Quad Configuration be used with Quad SPI AP Memory on OctoSPI interface?

Are series resistors required on ddr address line?
