In 'F407, bxCAN does not go to Bus-Off

In STM32F407, I have set bxCAN with CAN_MCR.ABOM=0 and CAN_MCR.NART=0. With the bus lines after transceiver (PHY) left open, after trying to transmit, transmitter transmits continuously forever, with CAN_ESR.LEC=0b011 for Acknowledgement Error (which...

Can SRAM1, SRAM2, SRAM3 be treated as one continuous memory region?

(This is regarding STM32H75x)SRAM1, SRAM2, and SRAM3 are separate in the memory map, but they are continuous - there are no gaps between them: Can they be treated as continuous with respect to the linker, for example:RAM_D2 (xrw) : ORIGIN = 0x3...
