Hi All, Until now with F3 and F0 devices we were able to upload and download firmware files to and from MCUs using "BootloaderDemo" application from STM. That software had both upload and download capabilites. With the newer G474 device however, we h...

Hello All,I got Classic CAN running on the FDCAN3 module of STM32G474CE device using MXCube and other example projects for STM32G474 devices.Problem is, all these example codes have a fixed baud rate of 1Mbps. My application requires thebaud rate be...

Hello All,I am trying to send some classic CAN messages via the FDCAN3 module on STM32G474CE device. I have only pins for FDCAN3 free. My FDCAN clock is PCLK1 with a frequency of 64MHz.When I try to transmit a CAN message, firstly there is no transmi...

Hello All,I was wondering if it is possible to clock another STM32 MCU (STMF031) using the single existing crystal oscillator that is currently clocking the main MCU (STM32F334). It could really save me space, power, cost and another clocking source ...

Hello nice people. I am supposed to develop a board that will have 2 STM MCUs (STM32F334 and STM32F01).Is it anyways possible to be able to program both MCUs (simultaneously or individually) using a single SWD port. I know how to do it using JTAG cha...

Hi @Imen DAHMEN Thanks for your reply.Is there any example on CubeMX software fro the STM32G4 series that describes this handling mechanism of BUS_OFF management?

THanks! @Community member .... it worked!

I am feeding the clock from external oscillator (crystal oscillator "CX3225SB32000D0FPLCC"). The question is if I can use the same crystal oscillator to feed the clock of another STM MCU on the same board. Aim is to save and oscillator placement.

Thanks TDK.After knowing that protocol wise it was not possible to do two MCUs using same SWD port, I set out to experiment. As it turns out, i don't actually need to have complete two separate ports having SWCLK, SWDIO and nRST, 3V3 and GND each. It...
