I am using:
Eclipse IDE for C/C++ Developers Oxygen Release (4.7.0)
GNU Tools ARM Embedded(arm-none-eabi version of GNU tools)
GDB SEGGER J-Link Debugging plugin
In my linker script, I have a memory segment(.myvars) which contains two discontinuous sections(.loadtable and .rawdata)
sections.ld:
.myvars :
{
__myvars_start__ = ABSOLUTE(.);
__loadtable_start__ = 0x60002000;
. = __loadtable_start__ - __myvars_start__;
*(.loadtable)
__rawdata_start__ = 0x60039000;
. = __rawdata_start__ - __myvars_start__;
*(.rawdata)
} > MYVARS
Illustration:
.myvars 0x60000000
|
| (unused memory)
|
| .loadtable 0x60002000
| |
| |
| |
| 0x60002000 + sizeof(.loadtable)
|
| (unused memory)
|
| .rawdata 0x60039000
| |
| |
| |
| 0x60039000 + sizeof(.rawdata)
|
| (unused memory)
|
0x60800000
Using sections.ld, Eclipse download 0x60000000 ~ (0x60039000 + sizeof(.rawdata)) to my device. But I hope I can just download .loadtable and .rawdata.
I know I can achieve by using this linker script(place section in two separate memory segment):
.myvars1 :
{
*(.loadtable)
} > MYVARS1
.myvars2 :
{
*(.rawdata)
} > MYVARS2
Is it possible to skip unused memory in one memory segment when downloading?
Any advice on this issue? I would be grateful for any suggestions.
