Re: [beagleboard] Re: Does Angstrom use hard float ?
Interesting.Nevertheless,the only reference to the fp operation context switch cost I've found is related to the VFP which we don't use with the Sitara under Angstrom. For some eventual interested people : In addition to saving and restoring integer registers, the kernel may also need to perform saving and restoring of VFP registers on a context switch. To avoid wasting cycles, this is done only when an application actually used VFP. As the VFP initialization code leaves VFP disabled, the first time a thread actually tries to access the floating-point hardware, an undefined exception occurs. The kernel function which handles this, sees that VFP is disabled and that a new thread wishes to use VFP. It saves the current VFP state and restores the state for the new thread Le mardi 29 octobre 2013 19:01:15 UTC+1, Dean Franks a écrit : I believe there is also an issue that using hard float makes context switches much more expensive. When hardfloat is in use, all the additional registers (possibly including wide vector registers) have to be saved and restore on every context switch regardless of whether the running application is using floating point or not. I have not looked at the Sitara but some processors have hardware assistance for this context switching that reduces the cost but with the exception of shadow register sets used in hard RTOS systems there is always a memory bandwidth cost. This context switching cost slows the entire system down. Our application is floating point arithmetic intensive so hard float is the better option, but I suspect there are many common workloads that do better under softfloat.

Doing it in hardware is much faster, but many microcontrollers don't have floating-point hardware like the Sitara here. In that case you may either avoid using floating point (usually the best option) or rely on an implementation in software, which will be part of the C library. In some families of controllers, for example ARM, the floating-point hardware is present in some models of the family but not in others, so gcc for these families supports both. Have you ever thought that softfloat could be used to be sure tobypass the analysis of hardwired math (Neon type) unit for each ? this could be done for historical reasons also: If I were about porting to a new board, softfloat allows me to be sure that my board will accept it. 2013/10/29 tee@gmail.com Thanks dlewin555. I understand that it's possible to use hard float. Some Android or arm Ubuntu version are using it. But for the default Angstrom (this the BeagleBone Black is delivered with). How can we check the hard float is not used ? I guess I could rebuild Anstrong using hard float but I am wondering why the default build doesn't use it ? I trust the Angstrom builder. It should have better knowledge than me. So if he preferred not to use the hard float it should have a good reason and I would like to know it.

Re: [beagleboard] poll() on a pin returns constantly even though there is no input
How are you counting your pulses? If you are firing interrupts faster than you can service them then you will be missing interrupts. There are only 2 ways to get faster interrupts on the beaglebone than what your are doing now and that is by either writing a kernel driver, to avoid the latency in the context switches, or by using the PRU.

Let me be more humble and do proper homework before posting from now on :-) I didn't have the time to work on this till now. You were right in pointing out usage of POLLPRI instead of POLLIN. I had tried both earlier and it did not work. Turns out it was because of the faulty pin (assuming here..pin stayed high always regardless of settings). I am using a different pin and POLLPRI and it is working fine. Although I did not understand the part about the interrupts. I am keeping a counter to count the interrupt event and using function generator, I am feeding pulses to BBB. It is a bare minimum code to to just increment counter upon every rising edge detected. I set the number to 10,000 initiallly and it takes wall clock time of 0.22 seconds to detect 1 rising edges. I wasn't sure if the number was correct so I increased the frequency of the pulses to 40,000 and even then the wall clock time is around ~0.2-0.3 seconds. Why might this be? How to check what's the maximum number of edges which can be detected without losing any edges. Thanks, sudhir.

That's per interrupt and simple ISR style routine. I would be suprised if you could get it much faster than that using standard read/write file techniques.

Re: [beagleboard] A General Question about the BBB
George B, Thanks for the input. The converter is rated at speeds UP TO 20 MSPS. I will not need all of that speed as I intend to sample it every 100 ns. Yes this is a situation where all I need to do is capture and store a reading from the A/D, wait until my 100 ns, has elapsed, capture store next, etc. After 30 iterations this loop will halt and the data will be processed later. So I really just need the speed to capture the data. Everything else can be done later So will the BBB be able to do this? I bought one already so I am in the game. It is the fastest popular board out there, or is it? Looking at the bill of materials I see it has 4 oscillators on board: 32.768KHz, 25 MHz, 24 MHz and 24.576 MHz. How can this run at 1GHz ?

Re: [beagleboard] On BeagleBone, are the pins for the second Ethernet port available on the expansion header
what about using the onboard ethernet for storage, and USB ethernet dongle for external connection? On Wed, Oct 30, 2013 at 3:48 AM, George B geor...@gmail.com wrote: Darn. I was thinking today that I would have a great application for a BBB if it had a second ethernet interface for a separate storage network. Say mount a ceph block device over one ethernet interface and use the other for business traffic with no reason to hit the SD or on-board flash at all while it is running. The primary bottleneck in the application I have been investigating so far is disk access. Flash is slow. Network storage is much faster. Separating storage from traffic is even better, particularly when you have only a 100M interface. I have been doing it with vlans but still, the two sorts of traffic compete for interface bandwidth. If I found a genie right now, one of my three wishes would be a dual ethernet BBB.

[beagleboard] Using BB to measure power
I'd like to use my BeagleBone Black to build a small power efficiency station for my school. For that I plan to measure power consumption using a current transformer and a voltage transformer, feed the data into a small fast database and show it through a web interface to the school staff. I see that 50 Hz are not a problem for BB ADCs, but I'm not sure at all using them is a good idea. Intially I planned to use the same voltage I must measure to power the BB. I'm starting from a circuit like the attached one (replacing the UA78M33 by a UA7805CKCT which provides up to 1.5 A output) https://lh4.googleusercontent.com/-Rh9IrbXEzAU/UnFV0UcdTSI/EAM/TduMV2A5CT4/s1600/adc.jpg Changing the R1/R2 divisor I can make the 220V signal lower , but I'd always get a signal with a negative side (-0.9V - +0.9V) in the best case. Same for the current transformer, after applying its output to a 100 ohms resistor. So, first, is it an awful idea to use BB for this purpose? If not, how can I avoid the negative part of the signal before feeding the BB ADCs?

Sorry Robert, by debug I meant the USB network device, which does appear on the ubuntu build but not debian.

Re: [beagleboard] Re: 4 user blinking LED's when trying to flash emmc! :(
Cool, no way near that! Okay, so I think I have narrowed down what just happened here! I fdisk'd and formatted, well thought I did, the sd card. But now I have come to realize depending on if a sd card is inserted at boot or not, changes the way mmcblk*'s are allocated. so my emmc actually got re-partitioned. Yeah, I should have double checked things, but why is it re-arranging like this and not just standardized to the emmc always specifically being on a certain mmcblk? So now, nothing will work. I get so far with ANY distro, be it emmc flasher or an image made to run off of SD, bam, blinking led's. dmesg reveals ifile errors. I am stuck in a read-only rootfs and I cannot do anything to fix the emmc. Hope some of this makes sense. On Wednesday, October 30, 2013 5:35:48 PM UTC-7, Gerald wrote: 3,000 times per bit.

[beagleboard] web server over bluetooth?
I'm scoping out a product idea for a device that would need to be controlled and monitored via Bluetooth with an android or IOS device. Initially I expected to go the route of making separate apps for each platform but the latest suggestion I've gotten has led me to the idea of controlling and monitoring the device via a webpage served over a bluetooth connection. If I'm understanding things correctly, the BeagleBone Black might work well for this. I'm looking for some wisdom on how this could be accomplished. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.
