Why STM32G473CBT6 program failed at 0x0800A000?

[Junde]

Hi there,

I am using STM32G473CBT6, and work with a bootloader and application.

When I set the application address at 0x08008000, everything works well.

However, when I change the application address to 0x0800A000, the application download fails, except when I download the bootloader (configuring it as 'erase all chip') first.

I checked the reference manual, and the flash is separated into 2K/4K on each page.

That means both 0x08008000 and 0x0800A000 addresses are at the page edge.

Why can't the application at 0x0800A000 work smoothly?

Thanks for your help!

Should be workable.

You'll need to look more critically what's placed in memory. Dump content. Dump Vector Table. Check .MAP file. Check SCB->VTOR settings.

What is "application download"? How do you "download" application? How do you know it fails?
