Touchgfx can I set the asset base address programatically

[c-abbott]

We would like to support a dual bank approach for background software updates.

This allows the TouchGFX assets to be flashed into the un-used bank in the background while original application is still running (using the other bank). Then the restart and bootloader re-flash of only the application is quick.

To do this we would need to set the "Base address of Assets" during startup, is this possible?

e.g.

- Current application has TouchGFX assets in Bank 2

a) background download of new package (application + assets)

a1) application -> external staging flash

a2) assets -> Bank 1 (the one not in use)

b) restart device

b1) staged application -> application internal flash

b2) header set to tell it to use Bank 1

c) application starts

c1) Sets TouchGFX asset base address to Bank 1 address

c2) Bank 2 is not in use for new time this process occurs

Hello,

I find it hard to understand how to get TouchGFX assets to be flashed while the application is using them.

If you have dual bank config, you will have two applications one running and one getting updated. Each application has its own TouchGFX assets. Unless I'm missing something from your description.

Let me simplify things:

• System has external flash divided into two sections A and B
• Application is compiled assuming assets are in section A
• Application is flashed into Internal Flash Memory
• Assets are flashing into either A or B Memory (determined AFTER compilation of application)
• Application is informed where it's assets are located (A or B), TouchGFX must be configured appropriately

When you ask is supported    NO

Is doable    Yes 

I mean this only is based on linker files. You prepare two and build for destination.
