[En-Nut-Discussion] Code size to large for one flash bank

[Andre Riesberg]

Hello all!

The codes size of my application grows and exceeds the limit of 262144 
bytes.
Now I got the message from OpenOCD:
"Warn: writing 262144 bytes only – as image section is 270228 bytes and 
bank is only 262144 bytes."
I use a board like the EIR with ARM7TMI and the Turtelizer2 with the 
command line: "C:\ethernut-4.8.3\nut\tools\win32\openocd.exe -f 
interface\turtelizer2.cfg -f eir.cfg".

So, I have two questions:

How I have to modify the config scripts to support the second flash bank?

It is possible to force some functions (module) into thump mode to save 
space? I have seen thump-interwork is enabled in NutOS. Is there 
something like __attribute__((thump)) for functions?

Greeting
