Good luck. Last time I attempted this I appeared to trigger a linker/library bug on some platforms: #10373

This one still in there. I'll start CI to get early results.
We might be able to help fixing some linkers but it might be more difficult if libraries in the tree are affected, Let's see

As there are some errors, seems that 'legacyalign' is not so deprecated...
Do you have some contact with ARM compiler team ?

[0xc0170]

We are hitting the same problem as before:

[ERROR] Error: L6244E: Exec region RW_IRAM1 address (0x20000108) not aligned on a 512 byte boundary.
Finished: 0 information, 0 warning and 1 error messages.

@kjbracey-arm the only way forward is to update all linker scripts affected or not? I do not recall any issue with prebuild libraries - is there any?

@0xc0170
What is the plan ? We keep the warning, and I close the ticket ?

[0xc0170]

Is there a tracking issue? If not, lets create one and track this. the warning should be fixed.
