Initialization functions in ARM gcc library

I found the answers for the first question in following webpage:

http://processors.wiki.ti.com/index.php/Semihosting

Could you help me on the second question? Or where can I find the source code for GCC library?

Thank you very much!

Hi,

I have checked the TI compiler experts on this. They are familiar with Linaro ARM gcc compiler which ships with CCS.

Please check whether below link helps you.

Thanks.

Hi Brighton,

Brighton said:

How the gcc library initialize the stack? In the link option and link command file, only one .stack section is defined, but as you known, each ARM mode (User, Supervisor, Monitor…) has separate stack, how the gcc library allocate the .stack section to each mode?

The information about the monitor stack size of each core is given in the source files of boot-monitor as below

in /sec/skernel.S

#define MON_STACK_SIZE_PER_CORE     RBL_MON_STACK_SIZE

.........

in ./config.h

:#define RBL_MON_STACK_SIZE 0x800

.........

Shankari

Hi, Rajasekaran,

I did not find the source code of the entry function "_start" in the link you provided.

I post this question to TI compiler form:

Thank you!

Hi, Shankari,

I think your information is about how boot monitor initialize stack. But I do not use boot monitor, I am writing bare-metal test code with GCC library.

Thank you!
