STM32H563ZGT6: Use both Flash banks for 1MB code

[Huijie]

Dear community:
I am currently using the STM32H563ZGT6 chip, and my code capacity exceeds 512KByte. When programming through CubeIDE, I can only burn to the 512KByte Flash of Bank1. May I ask if this chip can use Bank1 and Bank2 as a whole (as I have seen other ST series chips on the network that can operate in this way), and if so, how can I configure it?
Thank you.

Flash is contiguous. You can edit your linker file (*.ld) to reflect the 1 MB available and it should work.

FWIW, a new project in CubeMX for the STM32H563ZGT6 chip generated code which had the correct flash capacity shown in the linker file.

Dear TDK:

The allocation of RAM and Flash in my link file is also the same as yours:

Before raising this question, I searched the Internet for information about Dual Bank. Some STM32 series of chips can be configured with option bytes to choose whether to use Single Bank mode or Dual Bank mode. I roughly searched the manual for STM32H563ZGT6, but haven't found the relevant registers to configure it yet.

Best Regards!

Seems like an STM32CubeProgrammer bug. It does download successfully, though. At least it claims as such. Wonder if the flash is correct but it's not being read out correctly. All 0x00 seems unlikely to be real and more likely to be a bug.

Wonder if you could disable the "verification" step and see if it works.

I don't have an H5 board to test unfortunately.

Dear TDK:

Thank you very much for your suggestion. I tried to disable the 'verify after download' option, but the result is still the same. I am not sure if it is an issue with the STM32CubeProgrammer.

In addition, I used STM32CubeIDE for simulation debugging, and the console also prompted that the download verification was completed, as shown below:
