Re: [microblaze-uclinux] Microblaze GDB problems

Hi Falk,

I read somewhere that the "(old)" version should not be used. For me the new 
version compiles just fine using the v0.30 rc1. Very strange. Did you try 
rebuilding everything after enabling it ? What platform are you using ..? I 
am using Xilinx / Spartan 3E Rev D reference design. Linux 2.6.
