Re: debugging a NuttX linker problem
Thanks Greg. I found out that this resulted from an error in my Kconfig file. I was providing those functions, but they weren't getting compiled or linked due to my config settings. I corrected that Kconfig file, reran 'make menuconfig' and now my files are being compiled and linked. There's still problems compiling some stuff that I ported from the imxrt SD Card driver... working on that now... -adam On Thu, Apr 9, 2020 at 11:42 AM Gregory Nutt wrote: > > >> arm-none-eabi-ld: > >> > /home/adam/src/nuttx/nuttx-sama5d2-xult/nuttx/arch/arm/src/board/libboard.a(sam_bringup.o): > >> in function `sam_bringup': > >> > /home/adam/src/nuttx/nuttx-sama5d2-xult/nuttx/boards/arm/sama5/sama5d2-xult/src/sam_bringup.c:149: > >> undefined reference to `sam_sdmmc_sdio_initialize' > >> arm-none-eabi-ld: > >> > /home/adam/src/nuttx/nuttx-sama5d2-xult/nuttx/boards/arm/sama5/sama5d2-xult/src/sam_bringup.c:166: > >> undefined reference to `sam_sdmmc_set_sdio_card_isr' > >> arm-none-eabi-ld: > >> > /home/adam/src/nuttx/nuttx-sama5d2-xult/nuttx/arch/arm/src/board/libboard.a(sam_sdmmc.o): > >> in function `sam_sdmmc_cardetect': > >> > /home/adam/src/nuttx/nuttx-sama5d2-xult/nuttx/boards/arm/sama5/sama5d2-xult/src/sam_sdmmc.c:152: > >> undefined reference to `sdio_mediachange' > >> arm-none-eabi-ld: > >> > /home/adam/src/nuttx/nuttx-sama5d2-xult/nuttx/arch/arm/src/board/libboard.a(sam_sdmmc.o): > >> in function `sam_sdmmc_initialize': > >> > /home/adam/src/nuttx/nuttx-sama5d2-xult/nuttx/boards/arm/sama5/sama5d2-xult/src/sam_sdmmc.c:239: > >> undefined reference to `sam_sdmmc_sdio_initialize' > >> arm-none-eabi-ld: > >> > /home/adam/src/nuttx/nuttx-sama5d2-xult/nuttx/boards/arm/sama5/sama5d2-xult/src/sam_sdmmc.c:263: > >> undefined reference to `sdio_mediachange' > > These are ALL functions that must be provided in your board-specific > logic.

debugging a NuttX linker problem
Hi, I'm having problems debugging a linker problem. I added a new driver file (arch/arm/src/sama5/sam_sdmmc.c and and the corresponding .h) for the SAMA5D27 SDMMC peripheral. I added it to the chip/Make.defs file. nuttx compiles and I see the sam_sdmmc.o being compiled and added to libarch.a. But then I get this linker error at the final link step. Does anyone have any ideas how to debug this? Or fix it? The function names appear to identical in the .c and .h files, and there are no compilation errors. arm-none-eabi-ar rcs libboard.a > sam_boot.o sam_sdmmc.o sam_sdmmci.o sam_usb.o sam_appinit.o sam_bringup.o > sam_ostest.o sam_autoleds.o sam_buttons.o > make[2]: Leaving directory > '/home/adam/src/nuttx/nuttx-sama5d2-xult/nuttx/boards/arm/sama5/sama5d2-xult/src' > LD: nuttx > arm-none-eabi-ld: > /home/adam/src/nuttx/nuttx-sama5d2-xult/nuttx/arch/arm/src/board/libboard.a(sam_bringup.o): > in function `sam_bringup': > /home/adam/src/nuttx/nuttx-sama5d2-xult/nuttx/boards/arm/sama5/sama5d2-xult/src/sam_bringup.c:149: > undefined reference to `sam_sdmmc_sdio_initialize' > arm-none-eabi-ld: > /home/adam/src/nuttx/nuttx-sama5d2-xult/nuttx/boards/arm/sama5/sama5d2-xult/src/sam_bringup.c:166: > undefined reference to `sam_sdmmc_set_sdio_card_isr' > arm-none-eabi-ld: > /home/adam/src/nuttx/nuttx-sama5d2-xult/nuttx/arch/arm/src/board/libboard.a(sam_sdmmc.o): > in function `sam_sdmmc_cardetect': > /home/adam/src/nuttx/nuttx-sama5d2-xult/nuttx/boards/arm/sama5/sama5d2-xult/src/sam_sdmmc.c:152: > undefined reference to `sdio_mediachange' > arm-none-eabi-ld: > /home/adam/src/nuttx/nuttx-sama5d2-xult/nuttx/arch/arm/src/board/libboard.a(sam_sdmmc.o): > in function `sam_sdmmc_initialize': > /home/adam/src/nuttx/nuttx-sama5d2-xult/nuttx/boards/arm/sama5/sama5d2-xult/src/sam_sdmmc.c:239: > undefined reference to `sam_sdmmc_sdio_initialize' > arm-none-eabi-ld: > /home/adam/src/nuttx/nuttx-sama5d2-xult/nuttx/boards/arm/sama5/sama5d2-xult/src/sam_sdmmc.c:263: > undefined reference to `sdio_mediachange' > Makefile:184: recipe for target 'nuttx' failed > make[1]: *** [nuttx] Error 1 > make[1]: Leaving directory > '/home/adam/src/nuttx/nuttx-sama5d2-xult/nuttx/arch/arm/src' > tools/Makefile.unix:449: recipe for target 'pass2' failed > make: *** [pass2] Error 2step: > -adam -- Adam Feuer
