* Core dump in flash consists of header and data for every task in the system at the moment of crash.
|
|
* For flash data integrity, a checksum is used at the end of core the dump data.
|
|
* The structure of core dump data is described below in details.
|
|
* 1) Core dump starts with header:
|
|
* 1.1) TOTAL_LEN is total length of core dump data in flash including the checksum. Size is 4 bytes.
|
|
* 1.2) VERSION field keeps 4 byte version of core dump.
|
|
* 1.2) TASKS_NUM is the number of tasks for which data are stored. Size is 4 bytes.
|
|
* 1.3) TCB_SIZE is the size of task's TCB structure. Size is 4 bytes.
|
|
* 2) Core dump header is followed by the data for every task in the system.
|
|
* Task data are started with task header:
|
|
* 2.1) TCB_ADDR is the address of TCB in memory. Size is 4 bytes.
|
|
* 2.2) STACK_TOP is the top of task's stack (address of the topmost stack item). Size is 4 bytes.
|
|
* 2.2) STACK_END is the end of task's stack (address from which task's stack starts). Size is 4 bytes.
|
|
* 3) Task header is followed by TCB data. Size is TCB_SIZE bytes.
|
|
* 4) Task's stack is placed after TCB data. Size is (STACK_END - STACK_TOP) bytes.
|
|
* 5) The checksum is placed at the end of the data.
