FW flashing from Bootloader

[CJ007]

Hi , I am now working on FW upgrade using uart . Bootloader receives the application hex file through uart and flashes it .Then jumps to application , but facing some issues with flashing , flashing is not taking place. 

I am using NUCLEO-H723ZG board . I will attach the zip file of the project .

Do you have any error to share? any trace? any log?

Hi @urbito what do you mean? I only have these debug prints from docklight.After the flashing , no data is found at Application start address area, thus not jumping to application. I have a doubt whether is it because of the approach i took. Thats why I shared the zip file of the project I worked.

Obviously, your flashing does not work.
Do you verify each address ?

Or try to read out the flash after an update by the bootloader.
If this shows the same result, you need to work on your flash routine.
