Re: [microblaze-uclinux] FS-Boot, EDK 10.1 Spartan 500ERevD

[Hubert Bahr <hab@xxxxxxxxx>]

After downloading the image the new FS-boot is going to the 0x27fc0000 
address (as reported by the debugger with the breakpoint set just before 
the GO routine), which is the same address reported from the U-boot 
booted by the prebuilt FS-boot.   All The addresses reported during 
startup from linux reported when starting with the prebuilt FS-boot 
agree with those listed in the XPS address map and listed in the 
auto-config.h file so I am assuming that address mismatch is not the 
problem.  This now leaves me with some hardware mismatch that wasn't 
picked up during the bit mask generation.
When I run from the breakpoint It then reports

This is strange since that is in flash and when i boot from the prebuilt 
FS-boot it passes this point and continues to boot.  It is starting to 
look like it is having problems reading the Flash chip.   Any Ideas?
