It's in the file: core.c
In the function: adapter_init
Currently we have from the line: 1371
jtag = jtag_interface;
if (jtag_interface->init() != ERROR_OK)
{
jtag = NULL;
return ERROR_JTAG_INIT_FAILED;
}
We see that the pointer jtag = NULL when an error occurred.
At the end, the adapter be quit:
It's in the file: core.c
In the function: adapter_quit
Currently we have from the line: 1500
if (!jtag || !jtag->quit)
return ERROR_OK;
So at the end, when the adapter must be quit, nothing be made if jtag =
null even if the jtag adapter is active.
For me, the problem is like a malloc. When we allocate space in memory,
it's necessary to deallocate space in memory at the end of program.
So my solution with: ERROR_JTAG_INIT_FAILED_WITH_UNOPEN_DEVICE is an
easy and quick patch.
My proposition:
In the file: core.c
In the function: adapter_init
At the line: 1371
jtag = jtag_interface;
ret = jtag_interface->init();
if (ret != ERROR_OK)
{
if(ret == ERROR_JTAG_INIT_FAILED_AND_UNOPEN_DEVICE)
{
jtag = NULL;
}
return ERROR_JTAG_INIT_FAILED;
}
So the pointer: jtag is null only if the jtag adapter is inactive.
