Hello

LPC4337 have some banks of RAM(RAM1, RAM2, ...). Is it possible to do so would these pieces were considered a single entity?

Thanks.

Are you using both cores M4 and M0?
Are you using core IPC?
Are you thinking of sharing data between the cores?

You probably should read UM10503 a bit more since there are performance and reasons that there are these separate RAM regions.

I using one core.
I need that to several locations RAM were as one, so that I could make one big array.

Example: define uint8_t mas[65536] _BSS(RAM1);
At this writing I can not declare the array in Ram1.

No, you cannot 'merge' the memory blocks into 1 single space. You have to use it in the configuration provided.

It's a pity. Thanks for the answer.
