CFI flash with small working area?

Hi, I’m using a LPC 2212 with 8Mb external flash and 2Mb external ram.

I’m able to erase the external flash without problem.

I’m trying to flash a program in the internal flash (the init code) and the external flash (the data and code)

I’ve defined a working_area like this:

working_area 0 0x40000000 0x4000 nobackup
``` which is the maximum amount of internal ram available in a lpc2212

When I try to flash the program, I get the following warning:

not enough working area available(requested 32768, free 11996)


Is this only a warning and everything should be alright or it's fatal?

I've tried to define the working area like this:

working_area 0 0x820000000 0x8000 nobackup

But the flash process don't function at all. Is this because the working area is too far away?

Thanks for your help

This is just a warning, openocd would let you know if it could not allocate a working area.

Before you use any external ram for a working area, it may need registers configuring.

Ok thanks for the answer.

Yes, my external memory is correctly configured (registers) and I’m able to read and write it with openocd
