Hi,
I'm using LPC4357 ea Board with LPCXpresso v7 and I'm running the dual core example dc_sa_blinky/dc_sa_blinky_m0.
Reading the code of the m0 I see something that I don't understand about this IPC communication example.
The dimension of the SRAM assigned to m0 in MCU Settings is 32KB (while I expect it should be 40KB):
SRAM start 0x1008.0000, size 0x8000.
In the code the m0 will access the SRAM starting from the absolute address
#define SHARED_MEM_M0 0x10089F80
that is beyond the SRAM limit defined for the m0.
Could you help me to understand this point?
Thanks
Pietro
