As long as all apps with static IPv4 addresses call net_if_ipv4_addr_add().

So, yes, that should work!

Thanks

An interface always gets an address, hence I think that for both
static and DHCP cases the following would work:

<wait on semaphore signaled by a NET_DHCP_IPV4_ADDR_ACQUIRED callback >
#else

It probably doesn't matter how the address is acquired, but the
application needs to somehow know to wait for the IPv4 address
notification before proceeding. If DHCPV4 is configured, at least
the app knows it needs to wait in that case.

Could also remove the #ifdef in the app, have the app ask the net
interface if DHCP is supported (or if IP to be assigned by other
means), and if so, register to wait on a semaphore and wait on it,
otherwise proceed with a static IP address.

This does not really solve your problem, but Zephyr 1.6 contains a
legacy layer that provides all the APIs of the old kernels on top of
the new kernel. It's not a NOP to move to 1.6, since you might have
some issues with e.g. stack sizes, or some other > > idiosyncrasies,
but it might be less painful than you think.

About your issue: the first thing I always suspect with weird
behaviour like this is stack smashing. There is a kconfig option for
ARC that enables stack overflow/underflow detection. Do you have
that option enabled ?

Just to update you and the mailing list; I think the issue is one you
solved for 1.6. However, its not tracked on JIRA or in the release
notes so I didn't realize such a critical bug was not fixed in 1.5.
The commit in question is 5986ec040b. As this is a very specific
timing bug, we are still validating our code to be 100% sure its
fixed, but its looking good so far.

Sorry, I did not have much time to look at this. But yes, this looks
indeed like a problem even in the pre-unified kernel (per-1.6).

There is a global variable sys_clock_hw_cycles_per_tick which is set
in kernel/sys_clock.c from CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC, and is
later used in cortex_m_systick.c.

Looks like TI CC2560 runs at 48 MHz, so setting
CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC to 48000000 should be sufficient.
That's what I did for TI CC32xx (setting at 80 Mhz), and all the
timing functions worked out fine.

Hi all,

I'm having trouble understanding how to choose a value for the
SYS_CLOCK_HW_CYCLES_PER_SEC config variable.

I'm porting the CC2650 SoC from TI, which uses a Cortex M3 core.
Thus I plan to use the Cortex's embedded "SysTick" timer as a HW timer.
However, taking a look at drivers/timer/cortex_m_systick.c, the mentioned
CONFIG_SYSTICK_CLOCK_FREQ variable is not in fact defined anywhere.

Should I then simply use the frequency of the clock driving the Cortex core?
Or should I use the driver's interface in the SoC's init() function to set
it up,
and use the generated frequency in SYS_CLOCK_HW_CYCLES_PER_SEC?

Hi Michael,

When running "nc" in UDP, nc exits without waiting for reply from the target application (echo_server)

You may force nc to wait some time after all data are sent using -q seconds option. As in

$ echo foobar | nc -q 1 -u 192.0.2.1 4242

to wait for 1 second. Unfortunately the -q option may not be present in your specific implementation of nc. It seems there are a few and their names may vary, e.g. ncat, netcat. I haven't been using Zephyr net-tools project so I'm not sure what's the situation there.

For simple testing it's often enough to type

$ nc -u 192.0.2.1 4242

anything you type into the console will be send to the remote side and the response will be displayed. To exit you'll need to Ctrl+C manually.

Cheers,
Piotr

Hi all,

BTY, regarding the documentation in: https://www.zephyrproject.org/do

When running "nc" in UDP, nc exits without waiting for reply from the
target application (echo_server), unlike the description in the doc.:
Note
You will need to Ctrl+C manually.
$ echo foobar | nc -u 192.0.2.1 4242
foobar

I can see the packet being sent to target and replayed back in
Wireshark.
On TCP, nc does wait for response and I can see "foobar" printed and
Ctrl+C is needed to close nc.

Indeed, the documentation is wrong here. I will send a patch for that
one. Thanks for reporting this.

I searched over the web and read that because UDP is connectionless
protocol, nc is not supposed to wait for response.
Did I do something wrong?

No, you did everything right here :)

For example, do I need to add anything in the prj.conf file? (Like

No. That should come from the board config, which in your case should
be arduino_101_sss

I'm having trouble flashing the arduino101.
i've followed all the instructions available still, tho it says
download complete, the code doesnt seem to have been downloaded.

The code i am trying is the sample code provided, "blinky". The
LED doesn't light up. i have tried various pins apart from the on
board LED too.

 Is there any extra configuration that i have to do to make it
work?
Note: i am using a windows 8 pc

Hi all,

BTY, regarding the documentation in: https://www.zephyrproject.org/doc/subsystems/networking/qemu_setup.html#networking-with-qemu

When running "nc" in UDP, nc exits without waiting for reply from the target application (echo_server), unlike the description in the doc.:
Note
You will need to Ctrl+C manually.
$ echo foobar | nc -u 192.0.2.1 4242
foobar

I can see the packet being sent to target and replayed back in Wireshark.
On TCP, nc does wait for response and I can see "foobar" printed and Ctrl+C is needed to close nc.

I searched over the web and read that because UDP is connectionless protocol, nc is not supposed to wait for response.
Did I do something wrong?

Thanks,
Michael

Hi, I've just hit an issue with gerrit, can anyone help...

I pushed a series of 5 related patches into gerrit for review on the
net branch. The top two of those patches subsequently needed some
minor rework. After modifying the top two patches, when I try to to
push the 5 related changes again, gerrit gripes with:

remote: (W) No changes between prior commit 788f263 and new commit
e34791c

Are you sure that's the only message it gives? I always thought that
"(W)" at the beginning means "warning", I saw it on occasions like
commit message updated, but no patch content changed.

Looks like I can't re-push the stack of related changes because the
bottom of the stack didn't change.

How do I get around this and just push the top two changed patches ?

Hi all,

I'm having trouble understanding how to choose a value for the
SYS_CLOCK_HW_CYCLES_PER_SEC config variable.

I'm porting the CC2650 SoC from TI, which uses a Cortex M3 core.
Thus I plan to use the Cortex's embedded "SysTick" timer as a HW timer.
However, taking a look at drivers/timer/cortex_m_systick.c, the mentioned
CONFIG_SYSTICK_CLOCK_FREQ variable is not in fact defined anywhere.

Should I then simply use the frequency of the clock driving the Cortex core?
Or should I use the driver's interface in the SoC's init() function to set it up,
and use the generated frequency in SYS_CLOCK_HW_CYCLES_PER_SEC?

Best regards,
