Re: [ATTENTION] incubator-mynewt-core git commit: os; spin up OS
before calling. main() gets called in context of main task.
I pushed this change to develop.
You’ll need to update the newt tool as part of this change; as sysinit
calls should not include call to os_init() anymore.
After this change you can specify multiple calls to be made to your package
from sysinit().
Tell newt to do this by having this kind of block in your pkg.yml.
pkg.init:
ble_hs_init: 200
ble_hs_init2: 500
I.e. in pkg.init block specify function name followed by call order.
And app main() should minimally look like:
int
main(int argc, char **argv)
{
#ifdef ARCH_sim
mcu_sim_parse_args(argc, argv);
#endif
sysinit();
while (1) {
os_eventq_run(os_eventq_dflt_get());
}
assert(0);
return rc;
}
So there’s a call to mcu_sim_parse_args() (in case app can execute in simulator),
call to sysinit(), which calls all the package init routines, followed by this main task
calling os_eventq_run() for default task.
I might also want to lock the scheduler for the duration of call to sysinit();
but we don’t have that facility yet. This might be a good time to add it?

Re: [ATTENTION] incubator-mynewt-core git commit: os; spin up OS
before calling. main() gets called in context of main task.
Posted by marko kiiskila <ma...@runtime.io>.
Yes, at the moment it is not straightforward for packages other than BSP
to register devices. We should make sure we have at least some calls to
os_dev_initialize_all() from sysinit().
I.e. it would be nice to be able to have one package (device driver) be able to
register a device in it’s init routine, and then 2nd package could open that
device in their respective init.
So here’s the proposal:
- move the call to os_dev_initialize_all(OS_DEV_INIT_KERNEL) to take
place from within sysinit() itself, as the first thing before other packages
are initialized
- if os_dev_create() gets called after this point, OS calls device’s init
right away. And the device will then be available from that point on

Re: [ATTENTION] incubator-mynewt-core git commit: os; spin up OS before calling. main() gets called in context of main task.
Posted by will sanfilippo <wi...@runtime.io>.
So you are saying that there will still be well-defined places where things get initialized and that there will be defined ranges for these stages? For example:
0 - 99 Before os_init() is called.
100-199 in os_init() after os_init() code executes
200-299: in os_start() somewhere
Realize that the above are just examples and not meant to be actual ranges or actual places where we initalize.

Re: [ATTENTION] incubator-mynewt-core git commit: os; spin up OS
before calling. main() gets called in context of main task.
Posted by Sterling Hughes <st...@gmail.com>.
Also, one other thing to look at with the new sysinit changes. I think
we probably need to revise the ordering on device initialization.
Right now device init has the following:
/*
* Initialization order, defines when a device should be initialized
* by the Mynewt kernel.
*
*/
#define OS_DEV_INIT_PRIMARY (1)
#define OS_DEV_INIT_SECONDARY (2)
#define OS_DEV_INIT_KERNEL (3)
#define OS_DEV_INIT_F_CRITICAL (1 << 0)
#define OS_DEV_INIT_PRIO_DEFAULT (0xff)
And these stages are called:
In os_init(): PRIMARY, SECONDARY
In os_start(): KERNEL
I think it makes sense to more clearly map these stages to the new
sparsely designed sysinit stages, and add device init hooks throughout
the system startup.
Given the new sparse IDs, I\u2019m thinking that we could do it per-ID
range, i.e. os_dev_initializeall(100), os_dev_initializeall(200), etc.
Within that range, devices could be initialized by priority.
Thoughts?

Re: [ATTENTION] incubator-mynewt-core git commit: os; spin up OS
before calling. main() gets called in context of main task.
Posted by marko kiiskila <ma...@runtime.io>.
Ah yes.
Split applications should have the same settings for shared packages.
Forgot about this when replacing pkg.yml contents with the updates.
I’ll try a split use case today.

Re: [ATTENTION] incubator-mynewt-core git commit: os; spin up OS
before calling. main() gets called in context of main task.
Posted by Jacob Rosenthal <ja...@gmail.com>.
Looks like this breaks splitty as app, bleprph as loader
Error: Syscfg ambiguities detected:
Setting: OS_MAIN_TASK_PRIO, Packages: [apps/bleprph, apps/splitty]
Setting history (newest -> oldest):
OS_MAIN_TASK_PRIO: [apps/splitty:10, apps/bleprph:1, kernel/os:0xfe]
Setting OS_MAIN_TASK_PRIO in splitty to 1 made this go away..but Dont know
if theres other complications related to that though.Then it gets stuck
after confirming image and resetting while entering the app image at
gcc_startup_nrf51.s Default_Handler
