RE: [microblaze-uclinux] Petalogix BSP with XPS 9.2

["Curran, Tom" <Tom.Curran@xxxxxxxxx>]

Hi John,

Thanks for the work-around, but it doesn't appear to work for me.  No
matter what integer - binary, hex or decimal - I enter for
main_memory_start I get an error from libgen:

ERROR:MDT - petalinux () - integer value too large to represent
       while executing
   "format "0x%08X" $param_value"

For my XPS 9.2 platform the value is 0x86000000.  Any idea what the
problem is?

The Petalinux BSP tools don't yet support the MPMC, however there is a
simple workaround.

Use the main_memory_start and main_memory_size oparameters in the MSS
file (or SW settings), to manually specifiy the start and size of the
memory.

I'm having a look at what's required to get the MPMC support in the next
release of the BSP tools - stay tuned.

Regards,

John
