[arm-gnu] large footprint when building with CS-lite toolchain

[Bob Brusa]

Hi,
I am using the toolchain that came with eCos3.0 for a AT91Sam7s-based
platform. Now I upgraded to the most recent code sourcery lite version
(4.7.2) and find, that the program requires much more memory (although I
still use the eCos-library built with the old eCos3.0-toolchain). The
message I get is shown below:

arm-none-eabi-g++ -nostdlib
"-LC:\\Projekte\\TDSsw\\libs\\**tds_lib_12_install\\lib"
"-T..\\tds_1.ld" -Xlinker -Map -Xlinker tds_4_1.Map -o tds_4_1 util.o
usbs_at91.o usbs.o usb_cdc.o uart_dma.o tds_sm.o tds_res.o tds_hif.o

address 0x142386 of tds_4_1 section `.rodata' is not within region `rom'
collect2.exe: error: ld returned 1 exit status

The footprint is almost 20% bigger and the program no longer fits into the
flash of the uP. Do I miss something?

Let me add, that the previous version (4.6.3) of CS-lite did not produce a
footprint that was much different of the one produced by the
eCos3.0-toolchain.

Thanks for advice and regards - Bob
