I want to link a var to specific address, so I tried as follwing
Step1. using #pragma to define a section
#pragma section farbss "user_test_bss"
volatile int run_cnt1;
#pragma section farbss restore
#pragma section fardata "user_test_data"
volatile int run_cnt2 = 0x1234;
#pragma section fardata restore
Step2. define 'user_test_bss' in TASKING LSL file, like this
section_layout :vtc:linear
{
group
{
group (ordered, attributes=rw, run_addr=0x70001000)
{
select ".bss.user_test_bss";
}
group (ordered, attributes=rw, run_addr=0x70004000)
{
select ".data.user_test_data";
}
}
}
step3 compile test code and check .map file.
run_cnt1 | 0x90000004 | mpe:vtc:abs18
run_cnt2 | 0x90000000 |
In .map file, the address of run_cnt1 do not in user_test_bss section. I don't know what error occur in above step
I tried using key work "attribute" to link var in a specific address, but do not success
