Hi all,
My code was compiling/linking/running fine, I added a few functions,
and now when linking i get:
?ASlink-Error-Could not get 4 consecutive bytes in internal RAM for area
OSEG.
sdcc -v
SDCC : mcs51/gbz80/z80/avr/ds390/pic16/pic14/TININative/xa51/ds400/hc08
2.6.1 #4398 (Oct 2 2006) (UNIX)
I also had the same with the 2.6.0 release.
I compile/link with args like:
sdcc -c --iram-size 256 --model-large --xram-size 2048 --code-size
63487 --opt-code-size --profile -I/usr/local/sdcc/share/sdcc/include
-L/usr/local/sdcc/share/sdcc/lib/large SD_MMC.c
/usr/local/sdcc/share/sdcc/include/malloc.h:46: warning 187: ISO C90
does not support flexible array members
sdcc --iram-size 256 --model-large --xram-size 2048 --code-size 63487
--opt-code-size --profile -I/usr/local/sdcc/share/sdcc/include
-L/usr/local/sdcc/share/sdcc/lib/large main.rel adc.rel alarms.rel

ERROR: Couldn't get 4 bytes allocated in internal RAM for area OSEG.
Stack starts at: 0x7f (sp set to 0x7e) with 129 bytes available.
Other memory:
Name Start End Size Max
---------------- -------- -------- -------- --------
PAGED EXT. RAM 0 256
EXTERNAL RAM 0x0000 0x0593 1428 2048
ROM/EPROM/FLASH 0x0000 0xbdf8 48633 63487
If interested, i can post .map, .mem, .sym, .lnk.
Am I reading the error message correctly?: There is no more overlay
space? I have plenty of xram where I would think variables could be
allocated.
Should I be using different compile/link flags? My target processor is
analog devices ADUC842.
Thanks..
