STM32CubeIDE generates the hex file from elf file using below command.arm-none-eabi-objcopy -O ihex ${ProjName}.elf ${ProjName}.hexBut when i use the STM32CubeProgrammer, it generates the hex file which is smaller than that of STM32CubeIDE hex genera...

Hi There,I have searched a lot about the HAL_I2C_Mem_Write_DMA problem and seems like i have not found anywhere else this issue has been solved.Can anyone contribute if someone has solved it. Thanks

Hi There,While reading the data from I2C, I see that the master is missing to send NACK.Some fixed was done in https://github.com/STMicroelectronics/STM32CubeF4/issues/139 but those fixes are there in the code. But still sometime i see that NACK not ...

Hi Andrew,From STM32CubeIDE hex is 325KB and from STM32CubeProgrammer is 277KB. Yeah I compare it and most of the data were different. One of the different I notice is that the "gap fill" is zero from STM32CubeProgrammer but from STM32CubeIDE is 0xFF...

Hi Andrew,I found the solution from this link:-https://community.st.com/t5/stm32-mcus-products/hal-i2c-dma-bugs-why-does-this-simple-dma-code-not-work/td-p/136667 I need to add below code and enable the I2c event interrupt. Seems working fine. But I ...

Hi There,Yes HAL_I2C_Mem_Write works for me.I removed the I2C pins from the .ioc file and added back again without renaming the label name on SDA and SCL.Now i can see that it can send exactly the 6 bytes. But looks like there is no NACK and SCL is p...

Hi Evangelist,Calling a write function to write about 6 bytes. But it keeps sending contineously a lot of data.HAL_StatusTypeDef ret = HAL_I2C_Mem_Write_DMA(&hi2c1, (20 << 1) | 0, 4, 1, &to_reg[0], 6);

Hi @Imen.D , After a long run test, what i found was not the HAL_BUSY. It is about the HAL_ERROR. Seems like BTF flag was not set.I put the break point in below code. What could be the reason of BTF not been set? Is it noise on the signal or somethin...
