elf flash fail after mass erase

I'm trying to debug an error I get when I try to flash internal flash on my stm32f4 board. I first use the flash_erase command to do a mass erase using openocd: flash erase_address unlock 0x08000000 0x100000Then use the flash_write command to flash t...

Reasons to switch from STM32F746NGH6 to STM32H750XB in the context of a scientific application with HMI

Hi,A few days ago, I've asked the community about its opinion on the use of TouchGFX and FreeRTOS for developing a scientific instrument with HMI. Thank to you for all your suggestions which brought new concepts to our project.I come back to you to g...

Anyone got the eMMC on the STM32L4P5G-DK reading over 33 MBps (8-bit DDR) ?

https://www.st.com/en/evaluation-tools/stm32l4p5g-dk.htmlClocking at 52 MHz 8-bit DDR mode, should be able to get a lot closer to 104 MBps, trying to decide if it is the card or the bus/peripheral getting in the way.Also not impressed by the write sp...

I can't initialize stmpe811.

Hi, I'm working on a project with STM32F746 MCU and I used stmpe811 for touch controller but my code always going into hard fault error during initialization. I attached my project on the drive also I added the initialization part of code. Please hel...

I programmed the stm32l476 micro controller using stm32cube programmer, while running the code it shows an error 'Could not read flash size at address 0x1fff75e0' and the device disconnected. How could I solve this problem?

How can I determine root cause of a damaged ADC module on STM32L151?

I have a product that uses the STM32L151. One of our in-house test products was reporting inaccurate measurements on all ADC channels where the reported value is higher than it should be (example - battery voltage range is 0 to 10V. Real voltage is 8...
