STM32 MCUs Products

Do we have to change our code for operation on a version of the STM32 with larger flash memory? We currently use STM32F103RCT7 but may need to use STM32F103RET7 for stock availability. Is this possible with the same firmware or do we need to change it?

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...

UART Rx Threshold or FIFO Full interrupt not triggered

Hi, I created a test project to wake up L562MCU from STOP Mode when UART RxFIFO Threshold reached or full interrupt triggered or USER Button pressed.The project is based on Example project "UART_WakeUpFromStopUsingFIFO" for L562-DK. Test 1: Rx thresh...

STM32L476 SD DATA TIMEOUT problem

I am running into a problem with the SD card driver on the STM32L476. The DATATIMEOUT flag is occasionally set when trying to do a single block read using the DMA. I have set a breakpoint at the DATATIMEOUT flag in the SD IRQ handler. When the break ...
