Hi Experts,I'm almost a newbie at STM32F7xx even though I've been working with STM32F4 series.I wanted to handle the flash memory as IAP.I tried flash erase as same as what I do on STM32F4 but it failed.So I checked and found that thera are two kind ...
I am working on a STM32N6570-DK board, and I want to make sure that if I want to start a program on the external Nor Flash(the default mode), before using the Cubeprogrammer to download it, the boot0 and boot1 can both be set to 0, or boot0 has to be...
Hi All,I have a project that is using the STM32H562. I am having an issue using tim13 and tim14 to generate PWM outputs going to LEDs. The project uses timers tim2, tim3, tim4, tim13, and tim14 for a range of different PWM peripherals. For all of the...
Hi, I have an STM32F407-DISC1 connected to an Raspberry PI via I2S. The clock frequency is about 3MHz. The STM is receiving as slave on I2S2 and feeding data to a ring buffer. When the ring buffer is half full transmission on I2S3 is started (as slav...
I want to make a communication between 2 microcontrollers by can protocol i put after each microcontroller a can transceiver and the problem is that we send data but i other board we don't receive it, i mean after the second receiver we don't have p...
Hi, I first worked with CAN with STM32H563 with normal mode. It worked. Later Again I tried it is not working with same code. Loop back mode is working fine. I would like to use other pins for CAN since I am using PD0 and PD1. May I know which pins...
Hi, we are evaluating STM32L4A6VGT6TR, with our new product prototype. We are only suppling one 3.3V to the MCU as it requires. We have already included discharge circuit, and we can see this 3.3V rail will be completely discharged within 0.288s. How...
Hi,I am using STM32G474RET6 controller and would like to send and receive data in classic mode. I have configured all necessary parameters using cubemx but the hard fault occured when I call this function HAL_FDCAN_AddMessageToTxFifoQ(&hfdcan1, &TxHe...
Hello,I'm trying to port the example found here: https://blog.embeddedexpert.io/?p=1680 to NUCLEO-U385RG-Q.The example in the link is for STM32F411. I've successfully tried the example.Verbatim port of the code leads to USEF being set in GPDMA_C0SR.T...
I have designed a board with a STM32H573 and a KSZ8081RNACA PHY. As soon as I enable ETH clocks the ETH_DMAMR:SWR bit gets set.Verified:1. The 50 MHz clock from the PHY is present and stable (oscilloscope) at PA12. GPIO PA1 is configured for AF11, NO...
