Re: [microblaze-uclinux] Fwd: Troubleshooting installation of ICAP drivers

["David Montminy" <dpmontminy@xxxxxxxxx>]

John,

I had add some #define statements to get make to complete when there
is an ICAP in the design.  I can produce a image.bin but I have not
been able to display the bootup on the UART (it works with other
reference image.bin files).  I place the image.bin at address
0x30000000 and start at 0x30000000 but when I stop the processor XMD
says it exits at 0x00000000.  Could you look at my changes as see if
any of my assumptions were wrong?  I added the following:

xhwicap_srp.c
------------------
#define XNULL NULL

xhwicap_set_configuration.c
-----------------------------------------
#define xboolean u8
#define XTRUE 1
#define XFALSE 0

There was also a problem when update merged with your changes.  In the
file uClinux-dist/include/asm/processor.h at approxately line 75 there
are the following lines:
------------------------
<<<<<<< processor.h
       /* Thread will be started as a return from syscall
          rtbd r14, 4.
          Therefore, we adjust start PC address by negative 4 */
          regs->pc = pc-4;
========
       regs->pc = pc;
> > > > > > > 1.10
       regs->gpr[GPR_SP] = usp;
       regs->kernel_mode = 0;
---------------------------
I assumed that these lines should be reduced to:

       regs->pc = pc;
       regs->gpr[GPR_SP] = usp;
       regs->kernel_mode = 0;

Just a few small issues left to work out.  Thanks for all of your help,

David
