From mboxrd@z Thu Jan 1 00:00:00 1970 From: mkl@pengutronix.de (Marc Kleine-Budde) Date: Tue, 04 Dec 2012 15:46:51 +0100 Subject: linker problem with xip kernel and recent toolchains Message-ID: <50BE0CDB.5000704@pengutronix.de> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Hello, we've just discovered a linker problem with newer toolchains, that support --build-id and xip kernels. The resulting vmlinux is about 13 MiB big, but the xipimage ~2GiB. A look at the vmlinux's objdump shows that the .notes section is around 2 GiB and it's placed by the linker script into the RAM. With the ROM starting at 0x0 this results into a ~2 GiB big image. > [16] .data PROGBITS 88008000 0a0000 012aa0 00 WA 0 0 256 > [17] .notes NOTE 8801aaa0 0b2aa0 000024 00 AX 0 0 4 > [18] .bss NOBITS 8801aae0 0b2ac4 005414 00 WA 0 0 32 After discarding the .notes section in the objcopy (see patch below) the resulting binary images has a proper size again.
