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...
Resolved! How much user flash space is actually available on STM32H750xB devices?
According to the STM32H7 reference manual (RM0433), there is only a single 128kB sector of user flash space available for STM32H750xB devices (0x08000000 - 0x0801FFFF).Other devices in the STM32H7 family (H742xI, H743xI, H753xI) have 2 banks of 8 128...
