Hi all

I am trying to compile abd use the PPI for BF537 ... but when I  make the distribution file, i get the following error in the terminal:

drivers/built-in.o: In function `ppifcd_reg_reset':

(.text+0xcf52): undefined reference to `bfin_clear_PPI_STATUS'

drivers/built-in.o: In function `ppifcd_irq_error':

drivers/char/bfin_ppifcd.c:(.text+0xcfe4): undefined reference to `bfin_clear_PPI_STATUS'

can anyone suggest a solution or a work around for this problem?

Thank you in anticipatio of help.

something looks fishy as it builds fine for me for the BF537 target

make sure you have the macro defined:

$ grep bfin_clear_PPI_STATUS include/asm-blackfin/mach-bf537/*

include/asm-blackfin/mach-bf537/cdefBF534.h:#define bfin_clear_PPI_STATUS()              bfin_write_PPI_STATUS(0xFFFF)

hi micheal

It does not compile ... i ge the following error when i tried to make the uClinux distribution file:

drivers/built-in.o: In function `ppifcd_reg_reset':

(.text+0xcf52): undefined reference to `bfin_clear_PPI_STATUS'

drivers/built-in.o: In function `ppifcd_irq_error':

drivers/char/bfin_ppifcd.c:(.text+0xcfe4): undefined reference to `bfin_clear_PPI_STATUS'

do you have any idea on how to circumvent the problem

thanks

go into the kernel dir and run:

$ touch -c drivers/char/bfin_ppifcd.c

$ make drivers/char/bfin_ppifcd.i

$ make drivers/char/bfin_ppifcd.o

post the exact output seen from those commands and post the .i file as an attachment
