Hi, in my project on a Cortex-M4 with an external sdram I declare a large amount of data (63 arrays of 1MByte) placed in a dedicated section using scatter file.
The data are declared all in a separate module.
I noticed that the linking process is very slow and depends on the amount of data declared, is there a workaround?
Thank you, kind regards.

How slow is "very slow" ?
About one minute if I use the form:
unsigned char buffer[64][1048576] __attribute__((section("SDRAM"))); (where SDRAM is a (+RW) section in scatter file)
and few seconds if i use:
unsigned char buffer[64][1048576] __attribute__((section(".ARM.__at_0x60000000")));
