Hi, I'm writing some network code on a Netburner MOD5270, and I can't find the right function to call to rapidly check whether a listening socket has anything...
Hi, I need some assitance with the MOD5282, hoping someone can help me out. I have a time critical interrupt that occurs at a fixed rate of 10 mS to 250 mS....
do you have to take care of the external FIFO memory this inside the interrupt ? or could you rather wake up an idle thread when that interrupt fires, and then...
Reading the FIFO is handled in the interrupt routine. The FIFO needs to be fully read out before the next interrupt occurs. So, whether it is handled within...
... If you pass a timeout value of 0, it will not wait after checking the file descriptors. [That is, set the contents of the timeout structure to zero. If you...
Several comments: One fundamental problem is that you have 2 things that need interrupts. The UART and the FIFO. In your FIFO INTERRUPT macro setting the 2nd...
A select time out value of 0 waits forever. You need to use int ZeroWaitSelect(int nfds, fd_set * readfds, fd_set* writefds, fd_set * errorfds) as correctly...
Paul, Thanks for the feedback. If I let the UART interrupt the FIFO read per your approach below, how is this different than my current situation where the...
Thank you both, this is what I was looking for. Dunno how I missed this one on Friday. (right under select() in the documentation, no less. :P ) Cheers, Quin...
I'm having issues rebuilding the system library. Executing make clean yeilds the following error: make: makefile: line 74: Error -- Expecting macro or rule...
Paul, Thanks for all the help. I used "setenv.bat" in /nburn/ to set up the correct path to make. Once this was done I rebuilt the system files with my user...
Hello, I am interfacing to an external device(a microprocessor that simulates sensor data). The external device is connected to the mod5282's databus, address...
amir: you have physically connected the 5282 address, data lines to a chip that is de-powered while the 5282 is left powered-on? am i understanding this...
Hello Chris, Sorry for the confusion: The external device (which is a microprocessor that outputs simulated sensor data) is always powered on. I just turn off...
amir so your bussed peripheral ceases to ack, thereby hanging the read? what if you always support the read from the 5282 and return something that clues the...
Hi, Just wanted to mention that the address and data busses of the MOD5282 are unbuffered. So any corruption of those signals by an external device (for...
I setup an IRQ from the external device (the IRQ triggers when the device is ready for the netburner to read) to the netburner whose ISR posts to a Mbox....
I've noticed in the user manual that GetUartErrorReg is listed as a valid function for the SB72 platform. I would like to access the error register on the...
Hi all, I have a Netburner kit and am in "learning" mode (be kind :-). My company will have the need to provide http content in several languages, including...
The server just serves up whatever you put in the html subdirectory. So if you put in multibyte HTML files then you will get multibyte HTML files. If your...
(Again minus typos) The server just serves up whatever you put in the html subdirectory. So if you put in multibyte HTML files then you will get multibyte HTML...
We have had a number of customers report that they had very slow network debugging. We could not reproduce it here. Most if not all the people with the problem...
I have a program that uses a command/response protocol over TCP to allow external control of a set of services (FPGA control, LEDs, etc). For some reason I...
Are you calling listen each time? If so remember to close the listening socket. If you want multiple connections, it's easier to leave the listen open and then...
It sounds like your program is not processing the disconnect and closing the socket. Are you putting the socket into the exceptfds and processing the exception...
