Hello,I'm working with the stm32f439ZG and I have one question regarding the CAN bootloader.I'm trying to update one node via CAN interface. I have one network with 3 nodes (the node 1 is responsible for send the new firmware, the node 2 will receive...
Hello, I am using a STM32G473RC microcontroller and want to use usart3 to update the firmware.I also use the CAN-BUS on pin PA11 and PA12. These pins (PA11, PA12) are also USB pins (DP and DM).When I start the bootloader (BOOT = 1 + RESET), the "USB ...
I am using STM32CubeMX and HAL libs to send and receive CAN messages on an STM32F413ZH. stm32f4xx_hal_can.c tells me to #define USE_HAL_CAN_REGISTER_CALLBACKS = 1 which I have done in both main.h and stm32f4xx_hal_conf.h (if I don't put it in the la...
I know that they can not be used at the same time. But how can you switch between CAN and USB at runtime in the same application?
Hello everyone!I read many topics on this forum and it is really helpful but currently I try to solve my problem - unsuccesfully.What I want to do: program MPU through bootloader CANHardware: NUCLEO-L496, STLINK-V3. Crystal HSE soldered on NUCLEO (AN...
Posted on July 15, 2018 at 05:01Hi all,From what I've seen in the documentation, it looks like the bootloader defaults to a bitrate 125kb/s, and can be changed using the speed up command to the max of 1mb/s. It looks like the bootloader always defau...
In my STM32 software code three canbus messages sent (extended). When i connect the PCAN Can-USB tranciever i see my messages on the PC clearly. But after a while the state of bus gets "BUSHEAVY" and sending messages stop. Is the problem related with...
Hey there!I am currently working on a custom CAN IAP bootloader, using the STLink V3/SET as a USB to CAN bridge for programming FLASH. I am following the AN3154 doc for CAN protocol used in the STM32 bootloader and I am currently doing the erase comm...
Hello, I have some questions to you :), at first i am sorry for my bad english. But according to my question/problem. I have STM32F103CBT6 microcontroller, but i find that i can't use at the same time USB CDC and CAN interface, is this correct? I als...
HiI would like to know, if it is possible to flash my FW via CAN1 on a STM32F103 or only via USART1?AN3154 mentions the F1 series but AN2606 does only mention USART1.ThanxAndy
