The F429 uses both SDRAM and SRAM

Whether the two buses can be used at the same time? Winbond's SDRAM is used to find a high probability of reading and writing errors in SDRAM data。 but there is no problem with using ISSI. If you don't read or write to the external SRAM, it's fine。

Behaviour of conflicting CAN filters

There are two situations where I'm unclear on how CAN filters would behave. 1. Direct ConflictOne filter says reject 0x0 to 0x123One filter says send 0x0 to 0x123 to FIFO0 2. Different behaviour for a subset of messagesOne filter says send 0x0 to 0x1...
