I have an in- and out-buffer of 64 bytes that should fit in the near ram, but
it gets a linker error of:
link-Error-Could not get 128 consecutive bytes in internal RAM for area
ISEG.
Declaration:
__idata BYTE Out_Packet[64]; // Last packet received from
host
__idata BYTE In_Packet[64]; // Next packet to sent to host
Linker map shows:
Area Addr Size Decimal Bytes

-------------------------------- ---- ---- ------- -----

ISEG 0000 0200 = 512. bytes (REL,CON)
Value Global

0100 _Out_Packet
0140 G$In_Packet$0$0
0140 _In_Packet
BYTE is type defined as unsigned char but appears to use 4 bytes per element. I
tried changing them to int and long long, both of which seem to take up 4 times
what they should (8 bytes per int, 16 per long). What am I missing here?
