Re: [microblaze-uclinux] gdb cannot run the application

[Benny Chen <bennyc@xxxxxxxxxxxxxx>]

If you are trying to run gdb to debug a user application running on your 
microblaze platform then you should be using the microblaze-uclinux-gdb

Have a look at the following documentation.  I have tested it on 2.6 so 
it should work.

http://developer.petealogix.com/wiki/UserGuide/Debugging/UserApplications

Note that there are some error with the documentation that it refers to 
'mb-uclinux-gdb'  this should be 'microblaze-uclinux-gdb'


Cheers,
B.
