Hi,
How do you load the application in RAM? Are you building a ROMRAM type of application that relocates to RAM which you plan to debug using the GDB stubs? Can you dump the memory content at address 0x100000 and forward, is the memory initialized?

Subject: [ECOS] GDB Issue on MPC837X
Hello,
I am trying to get gdb working on a MPC847X ERDB eval board using the serial port.
Basically, I cannot get gdb to start executing the application loaded in RAM at 0x100000.
Logs below.
Any help appreciated.
Thanx.
