Hello,
I am trying to use a weak function in able to provide a board specific initialisation. To be more specific, I am trying to use the __weak board_ehci_hcd_init function in the usb driver code which is called in ehci_hcd_init, the strong function being defined in the board file. This is on lines similar to what I see in the ehci-mx6 driver and some mx6 board files like nitrogen's.
Getting a linker error on compiling which is perplexing me at the moment.
[snip] drivers/usb/host/built-in.o: In function `ehci_hcd_init': /home/sanchayan/uboot/u-boot/drivers/usb/host/ehci-vf.c:185: undefined reference to `board_echi_hcd_init' /home/sanchayan/gcc-linaro/bin/arm-linux-gnueabihf-ld.bfd: BFD (crosstool-NG linaro-1.13.1-2012.09-20120921 - Linaro GCC 2012.09) 2.22 assertion fail /cbuild/slaves/oort14/crosstool-ng/builds/arm-linux-gnueabihf-linux/.build/src/binutils-2.22/bfd/elf32-arm.c:7498 /home/sanchayan/gcc-linaro/bin/arm-linux-gnueabihf-ld.bfd: BFD (crosstool-NG linaro-1.13.1-2012.09-20120921 - Linaro GCC 2012.09) 2.22 assertion fail /cbuild/slaves/oort14/crosstool-ng/builds/arm-linux-gnueabihf-linux/.build/src/binutils-2.22/bfd/elf32-arm.c:13830 /bin/sh: line 1: 1110 Segmentation fault (core dumped)
Perhaps I am overlooking something trivial? A diff is attached, the changes are minimal. I am using our local branch of uboot at 2015.04 and the gcc linaro toolchain.
Thanks & Regards, Sanchayan Maity.
