Hi,
I’ve seen several discussions about the use of series resistors between the STM32H753 and external SDRAM, and I’d like to get some clarification. I’m currently building a prototype of my custom board and noticed that on the STM32H753I-EVAL board, 33 Ω resistors are used on the SDRAM interface, while in other designs 0 Ω links are used instead.
For a first prototype, would you recommend starting with 33 Ω resistors (as on the eval board), or starting with 0 Ω and only switching to 33 Ω if I encounter signal integrity issues?
Thanks,
Mohammed
