RE: gdb internal error

[Andrew Volkov <Andrew dot Volkov at transas dot com>]

I'm sure it a bug in BFD part of gdb, and it was due to absence of physical
section .text in your link script, but workaroung exist. 

Try define in SECTION part something like this:

 .text : 
 {
 *(.rodata)
 *(.textSwap)
 *(.textSort)
 } > DRAM
