Hello to everybody. I’m working on the microcontroller STR710, using OpenOCD. I succeded in making my programs run from both RAM and Flash, thanks also to the help that I received in this forum, many thanks for it. But I still have a problem. I’m using linker and startup files from Anglia, but what about the following lines in the linker file about RAM?
MEMORY
{
DATA (rw) : ORIGIN = 0x20000000, LENGTH = 0x00010000
XDATA (rw) : ORIGIN = 0x62000000, LENGTH = 0x00400000
}
I don’t know the meaning of the section XDATA. If we continue in reading the file, we can see the following lines:
.text :
{
KEEP(*(.vectrom))
KEEP(*(.init))
(.text .text.)
(.gnu.linkonce.t.)
*(.glue_7t .glue_7)
KEEP(*(.fini))
*(.gcc_except_table)
} >XDATA =0
. = ALIGN(4);
So, using these settings, the “.text” section will be loaded in XDATA. I use this file and the program compiles properly, but when I try to debug it using OpenOCD, I don’t succed in it, it seems it hasn’t written the “.text” area in XDATA or it can’t debug from XDATA…
So I substituted XDATA with DATA, so .text is loaded in the DATA section and this is ok for normal programs, but not for programs that have a big “.text” area. Can anyone help me? Thanks in advance
