Re: [microblaze-uclinux] undefined __down_interruptible and __up

Hi Viictor,

I have a device driver, I compiled the driver on petalinux-v0.30-rc1. The device driver declares a semaphore using: 

MODPOST 1 modules

WARNING: “__up” [……/scull.ko] undefined!

WARNING: “__down_interruptible” [……/scull.ko] undefined!


Can you please add

EXPORT_SYMBOL(__down_interruptible);
EXPORT_SYMBOL(__up);

to linux-2.6.x/arch/microblaze/kernel/semaphore.c

and report if it solves the problem?

Thanks,

John
