I am using a bootloader as STM32F405.Before Jump_to_application(), I want to keep the GPIO status in API, but what should I do?After the GPIO PIN is output "high" from the current boot firmware, it runs the jump_to_application().The parameters are in...
I have been using this solution to jump to the ROM bootloader and that is working fine. However, it only works if the chip is coming out of reset and none of the peripherals are initialized, FreeRTOS scheduler not running, etc. Basically the chip nee...
I'm using stm32flash (https://sourceforge.net/projects/stm32flash) as my host on a raspberry pi. It's connected to the STM32H750 using I2C.Steps:Upload the code onto the STM32./stm32flash -a 0x4E -w stm32-blinky.bin -v -R /dev/i2c-1 stm32flash 0.6 ...
Hello,I am trying to do an OTA upgrade on my STM32H750. I am using QSPI flash in dual mode as the IC does not have so much internal flash for my application. My application is running FreeRTOS and does have a LCD screen. So I build a bootloader to co...
I have a board that relies on flashing the MCU using the integrated bootloader via UART1.While this works well for the M7 (Bank 0x08000000), flashing the M4's Bank at 0x08100000 is not successfull.While most bytes are written okay, a small block in t...
I am trying to allow an STM32G070x MCU I'm using in a project to be (OTA) updatable by a second MCU. To that end, I followed Viktor Vano's instructions, here and here.As described there, there is a (secondary) bootloader programmed at flash address 0...
Hello I'm migrating my STM32F072 project to the STM32L072.In my original project (F072) I can jump to the DFU bootloader by software via a function located before SystemInit.I tried to convert this to be used by L072 by changing the address of bootlo...
Posted on January 08, 2015 at 04:51I understand this question has been asked before. I searched the forum and view these three threads: ''How to program the application flash file (hex file) in chosen flash area by using ST-LINK for STM32F0''''Flash...
Background: If I used the Boot0 button, reset, and the demo-flasher, everything works as it should. Problem:My application needs to jump to system memory. I've read many post on this which should be fairly straight forward but after jumping to Sys...
Hello,I have a problem with the bootloader on a Nucleo G071RB. I have no problem reaching the bootloader to download some new firmware in UART, after a reset and Boot0 pin set as it should, the bootloader responds to messages send through UART : when...
