Hi Eric,
I forgot to mention 2 important changes that I had to do when I started
with this HW:
*1.*
A little patch is needed in tos/system/SimpleFcfsArbiterC.nc and
tos/system/FcfsArbiterC.nc
(http://mail.millennium.berkeley.edu/pipermail/tinyos-help/2012-February/053892.html)
Wrong order while initializing hardware resources (SPI is initialized
later than Radio; SPI should be ready before initializing Radio)
tos/system/SimpleFcfsArbiterC.nc:
uses interface ResourceConfigure[uint8_t id];
}
implementation {
- components MainC;
+ components RealMainP;
components new FcfsResourceQueueC(uniqueCount(resourceName)) as Queue;
components new SimpleArbiterP() as Arbiter;
- MainC.SoftwareInit -> Queue;
+ RealMainP.PlatformInit -> Queue;
Resource = Arbiter;
ResourceRequested = Arbiter;
tos/system/FcfsArbiterC.nc:
uses interface ResourceConfigure[uint8_t id];
}
implementation {
- components MainC;
+ components RealMainP;
components new FcfsResourceQueueC(uniqueCount(resourceName)) as Queue;
components new ArbiterP(uniqueCount(resourceName)) as Arbiter;
- MainC.SoftwareInit -> Queue;
+ RealMainP.PlatformInit -> Queue;
Resource = Arbiter;
ResourceRequested = Arbiter;
*2.*
Comment out "inline void UCTR(...)" at
tos/chips/CC2520/CC2520DriverLayerP.nc:433. (Strange error message:
syntax error before '0x10') <-- as for this, I still don't know what the
problem could be :(
If you find something interesting regarding my problem, please let me
know. Thanks.
Best wishes,
Adam

not yet. Still building. hope to have a compile working today.
I did order a 2520 EVM module as well as a 2520/2591 module. So now
have the same environment as you.

Not enough information.
Can you push your tree to your account on github? If you don't
have a github account please get one so you can push your code
up to it and then I can look at it.
I didn't have a github account so I created one quickly. I hope I
did everything right. Here is the address of my current tree:
https://github.com/erdelyiadam/prod/tree/AE
I created a new platform under the name of "nthfs".
Then I can see how you have things wired.
Since you get one event it probably isn't a wiring problem but
some other kind of failure.
Sorry, my description was ambiguous. I get no event at all, I can
see only the first SFD signal and only on the oscilloscope. So on
SW side I got nothing abour SFD.
What does your h/w look like? How is the 2520 wired to the 5438a?
The HW I'm using is an MSP-EXP430F5438
<http://www.ti.com/tool/msp-exp430f5438> board from TI with a
CC2520EMK <http://www.ti.com/tool/cc2520emk> RF modul.

Hello Everyone,
I'm (still) trying to interface the MSP430F5438a uC with the
CC2520
radio chip. (I'm using the tp-freeforall/prod repo)
Now I'm facing the following problem:
When sending out (TX) messages the SfdCapture.captured event
never
fires, except after boot-up for the first time.
- I captured some of these "first packets" with a CC2531 USB
dongle and
TI Packet Sniffer and the result looks like this every time:
41 88 11 22 00 <tel:41%2088%2011%2022%2000> FF XX XX XX XX
XX XX XX XX XX (where XXs are different
every time, but the length is the same, 15)
- I also measured the signal with an oscilloscope on GPIO4
of CC2520
(which is set to SFD by default (based on CC2520 Datasheet /
SWRS068)
and connected to P8.1 on MSP430F5438a) and I can see this
first SFD
signal after boot-up, but the high-level of the signal is
only around
0.3V. (I don' really understand why so low.)
- I tried to remap the timers, because by default the radio
uses Micro
timer (my HplCC2520.nc is based on sam3s_ek) which is mapped to
Timer1_A, but the P8.1 (the SFD signal from CC2520) is mapped to
Timer0_A which is a T32khz timer, so I replaced Timer0_A and
Timer1_A
with each other, but it didn't get any better.
At the moment I'm out of ideas, if anyone could give me a
hint what the
problem could be, it'd be great.
(the above mentioned event can be found in
/tos/chips/cc2520/CC2520DriverLayerP.nc around line 1600)
Thank you in advance.
Best wishes,
Adam Erdelyi

It would be great if you could help. I feel totally lost.
