Re: serial speeds

Yeah I am not sure how to test the speed of the transmitter, but settings-wise it's set to 115200 baud, which is something like 14.4kB/s, right (according to a Google search)? I need about 15 bytes of data at a time, which should only take 1ms. That's what I would like to see. 5ms would be okay, too...

Re: read() with or without select()?

Thanks, I made a different thread for the speed problems, and you replied in it, so I will address that there. Thanks for the tip on read() only.

serial speeds

Hi, For some reason our serial speeds are really slow, and I am out of ideas. I stuck the StopWatch code around it to see how fast it is, and it seems to alternate between 13ms and 55ms, those two values, over and over; more regularly to be random. The code: https://gist.github.com/c2e4ddd4f76281316...

read() with or without select()?

Hi, From the docs, it looks like read() blocks the task. We're having some trouble speeding up the read over serial and were wondering if sticking it inside a select() conditional would speed the whole thing up. Just intuitively, it shouldn't be faster, right? read() blocks until it sees data, which...

No more autoupdate

Hello, I updated my NNDK and eclipse and all. Now, with the netburner demo app running on the board, I can't autoupdate it to flash it with my app. It worked flawlessly before I updated the NNDK. Did I miss anything? I can see the board in the IPTool and AutoUpdater find, but not always. Sometimes I...

Re: undefined reference to Foo

Hm, I think this may be a gcc bug:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27574

Seems like the reason it doesn't stop in a constructor is because it doesn't create debug symbols for it. Weird.

connect to board from OSX

Hello, I am trying to connect to the netburner board via my Terminal in OSX. I installed the driver for the USB->Serial adaptor and have a tty. and a cu. device show up in /dev. I tried connecting to it with cu -s 9600 -l /dev/cu.<whatever>, which says I am connected, but nothing comes through. I al...

Re: undefined reference to Foo

Tod, Thanks for the advice. I looked at the queue and deque, but decided to implement my own so as not to be dependent on the STL. That's a good thing to keep in mind though. About the start variable, you're right, and funny that you bring that up. I got access error traps because start wasn't initi...

Re: Developement under Linux

Are there any news on making this available somehow? Windows is making me hurt myself.

Thanks!

gdb proper

Hello, Has anyone tried using gdb command line from a Mac or Linux box to remote debug the board? I got the app waiting at Initialized GDB TCP, and connected to it via gdb, which tells me: Remote debugging using 192.168.3.30:2159 0xe0e40c02 in ?? () Any idea where to go from here? Thanks! Christoph
