Hi Jehudi,
To further debug the conditions around the assert, please apply the attached diff.
And send me which assert is hit.

-----Original Message-----Thanks for all the info. Before we investigate whether the CSR8510 is doing something it should not, can we double-check additional stack sizes? Can you set: CONFIG_BT_HCI_TX_STACK_SIZE to 1024 and CONFIG_BT_RX_STACK_SIZE to as much as you can, 4096 ideally I see that your receive thread stack (CONFIG_BT_RX_STACK_SIZE) is getting near the 2048 limit, which is huge. Are you doing a lot of complex operations in BLE callbacks? Thanks, Carles

Question regarding to implement a UDP client using net_app APIs
Robert Chou
Hi,
I’m comparing implement a UDP client by using net_app and net_context APIs.
When using net_context APIs, I’m able to send and receive data from any peer (register receive callback through net_context_recv()). Since UDP is connectionless, it’s an expected behavior as long as I don’t call net_context_connect().
However, if I use net_app APIs to implement a UDP client, it seems that I’m unable to do the same thing. I’m able to send out the data to the requested peer by calling net_app_send_pkt(). However, I’m unable to receive the data from the peer by registering the receive callback through net_app_set_cb() and without calling net_app_connect().
Is this an intended behavior of net_app API?

Bluetooth mesh sample (mesh) - Hard Fault
laczenJMS
Hi,
Running the bluetooth mesh example (samples/bluetooth/mesh/) on a nrf51822 results in a Hard Fault. The provisioner is meshctl (bluez). After successful provisioning I disconnect from the mesh, when connecting again the hard fault appears: Kernel stacks: main (real size 512): unused 228 usage 284 / 512 (55 %) idle (real size 256): unused 200 usage 56 / 256 (21 %) interrupt (real size 2048): unused 1656 usage 392 / 2048 (19 %) workqueue (real size 1024): unused 676 usage 348 / 1024 (33 %) prio recv thread stack (real size 448): unused 144 usage 304 / 448 (67 %) recv thread stack (real size 1396): unused 32 usage 1364 / 1396 (97 %) ***** HARD FAULT ***** Executing thread ID (thread): 0x20001f04 Faulting instruction address: 0xf63c Fatal fault in ISR!

Re: Remove/change fs_truncate() API
On Tue, Sep 05, 2017 at 10:18:01AM +0200, Andrzej Kaczmarek wrote:

Yes, currently I return ENOTSUP for this. My only concern here is that thisOnly if the fs_truncate() for 0 offset can be implemented atomically. I'm not sure how that would work for operations given by file descriptor, since the file is already opened. I think there should be as little between the Zephyr fs API and the NFFS API. A developer using a filesystem on an embedded system needs to understand what is happening (and specifically what will happen if power is interrupted during an operation). That means we should avoid having API calls that try to simulate behavior that isn't there. For example, if fs_truncate() somehow were to use fs_open() by figuring out the filename the existing file descriptor used, and opening with truncation in NFFS, this would cause an additional file descriptor to be used for the operation (even if just momentarily). In a system design, it is possible that the developer will configure the exact number of file descriptors available, which could cause this operation to either mysteriously fail, or succeed, but use the file descriptor temporarily, causing another thread's filesystem operation to fail. So, my suggestion would be to add the O_TRUNC (or equivalent) flag to open, make fs_truncate() return ENOTSUP, and just document this. If arbitrary truncation, or truncation of an open file is desired, that can be added later to NFFS, and then to the API. David

My only concern here is that this means there is no way to open existing file and truncate it other than fs_unlink() + fs_open() due to missing flags in fs_open() I mentioned above. BTW, does it make sense to have fs_truncate() work for '0' as offset and return e.g. EINVAL for other values? This should be doable I think. David Best regards, Andrzej

Re: how to conditionally link a static library in Zephyr?
Nashif, Anas
Hi, The Kconfig options (macro) you define need to be included (sourced) in the overall Kconfig structure of zephyr, just adding an option to prj.conf does not give you what you want. This is possible and there are a few examples for doing this, see
tests/benchmarks/object_footprint/: This test uses local Kconfig variables samples/application_development/: A few samples for linking external libraries and 3rd party code.

Sent: Sunday, September 3, 2017 2:29 AM To: zephyr-devel@... Subject: [Zephyr-devel] how to conditionally link a static library in Zephyr?
Hi there, I’m trying to build my zephyr app with a static library which is not provided with its source code. I can achieve the goal by adding the following two lines in my project’s Makefile:
export LDFLAGS_zephyr += -L$(SOURCE_DIR)/mylib/ export ALL_LIBS += mylib
However, I want to get the static library linked only when a specific macro is defined, like below
Ifeq ($(CONFIG_ENABLE_MYLIB),y) export LDFLAGS_zephyr += -L$(SOURCE_DIR)/mylib/ export ALL_LIBS += mylib endif
Here `CONFIG_ENABLE_MYLIB` is a macro defined in a Kconfig file somewhere.
However, the static library can’t be linked if I used the conditional option even though the macro CONFIG_ENABLE_MYLIB is enabled in my “prj.conf”.
So, I’m wondering if anybody has done the similar work and can you share the experience? Thank you very much!
Regards, Jun
