Replace STM32 firmware from application code
I have an STM32F429 custom board that when in product only supports CAN bus.I need to be able to upgrade firmware while in product over CAN bus. I know the bootloader supports this but sadly our custom board has been designed to use different CAN bus...
Resolved! What frame buffer is used on the STM32H735IG Discovery?
Hi!Forgive me if this is a simple question:This board comes with two OctoSPI:s of 512Mb and 128 Mb respectively, the latter is using HyperBus. Is the default config. setup using any of these memories as the display's frame buffer or is the internal R...
STM32L462RE - SPI slave duplicated first word
Hi,I am porting a project from STM32F103RE to STM32L462RE.I have an issue with the SPI slave.My problem is that in the data I send back to the master always has the first word duplicated.I found out that more people have a similar issue:https://comm...
STM32L562QEI6 does not start up at power on
Hi All, I have a start up problem with the STM32L562QEI6.While using the STM32CubeIDE debugger, the code runs fine but without the ST-LINK/V2 connected, the board remains "dead" after applying the power supply.When I manually pull the nRST pin down b...
Resolved! How to start PWM without using HAL
I have initialise the code in Low layer(No HAL).So now i have config the timer channel as PWM generation output and set clock, ARR,duty cycle as per the requirement. Earlier when I was using HAL, after initialising i can just wrote HAL_TIM_PWM_Start ...
What is wrong with the interrupt processing
Hi,I migrated a firmware initially written for a STM32F303 to a STM32G474.The firmware runs perfectly on the STM32F303.It also runs on the STM32G474. But after a moment the program get stuck and the FDCAN in Classic Mode runs out and the FIFO gets ov...
Why are my temperatures not the same between devices?
Hi,We have produced a set of devices with the stm32L072 mounted. It measures the internal temperature sensor, which result in around 29 degrees for most of the devices. Which is what we can expect, right? For the internal temperature sensor.But a few...
STM32F407 Flash programming error (PGSERR and PGPERR)
Posted on January 03, 2018 at 10:32In FLASH banks 0 and 1 I placed a simple bootloader which jumps to bank 4 where the main code is placed. Banks 2 and 3 are used as emulated EEPROM (see AN3969 application note). I wrote some unit tests to check if ...
CAN Communication b/w STM32F753Z8 and Arduino Board
Hello Everyone,I have a two arduino boards communicating with each other on a CAN Bus. Arduino is connected to CAN Bus via MCP2515 .Both arduino are communicating correctly with each other. Here is an example of my transmitter on arduino:/**********...
