RE: [microblaze-uclinux] Question about Petalinux bootability on customized hardware system

["Kevin Chen" <kevin.chen@xxxxxxxxxx>]

Hi, John,

It works when the DCACHE is turned off.

Bootstrapping is done with a custome designed loader which moves uclinux
image.bin from flash to DDR memory.  The hardware design has flash at
address zero and there is no LMB BRAM. The vector table is
setup/programmed into the flash before uclinux execution. This flow
works but it will require some manual configuration, like setup the
vector address for uclinux in the loader. 

Any information about booting uclinux from flash at address zero, which
would combine the loader? 

Thanks
Kevin

OK, let us know.

I'm not quite sure what you mean here - can you clarify?
