ATMEL^TM AT91SAM7X and AVR32 / Re: PHY configuration

« on: February 14, 2008, 05:02:31 PM »

Hi,

There is a strange effect.
1. When I compile and debug with CrossStudio, there are non-stop interrupts and the value of AIC_IPR (0xFFFFF10C) is 0x80010000. Even the breakpoint in watchdog.c cannot stop the process.
2. When I compile and debug with IAR, the breakpoint in watchdog.c stops the process every time.

I cannot understand why there is such a difference between the two compilers.
Help me, please, if possible.

Alexander

Hi Mark and all uTasker users,

I am trying to work with AT91SAM7X256 and the PHY interface Teridian 78Q2123.

I have changed the following in app_hw_sam7x.h :

#define PHY_IDENTIFIER          0x0181b8a0
#define PHY_MASK                0xfffffff0
#define PHY_ADDRESS_ (0x1f << 23)

to

#define PHY_IDENTIFIER          0x000E7237
#define PHY_MASK                0xffffffff
#define PHY_ADDRESS_ (0x1<< 23)

but it still doesn't work.

If someone have experience with this PHY, help please.
I can provide the Teridian's pdf and my scheme, if needed.

Regards, Alexander
