[beagleboard] why eSATA in X-15?
My home desktop PC has an eSATA port. A few months ago I wanted to buy a hard disk for backup and could not find any at a reasonable price with an eSATA port. I bought one with a USB3 port. My question is why was eSATA interface chosen for the X-15?

Hi Robert, Is the port on the X-15 eSATA or eSATAp [1]? The picture [2] says eSATA, though since Gerald said USB 2 is also supported I guess it is eSATAp. If it is indeed an eSATAp port then the cable you suggested is the best solution in my view because it provides power. The follow-up question is how much power can the X-15 provide at 5 V and at 12 V.

[beagleboard] how to RMA?
So I have a problem in one of my BBs, and I want to see if I can RMA it. I went to the page below and filled the form with all the required data. When I click on the Submit button, instead of sending the data, I get asked to set up an email account in Seamonkey (the browser I am using). I am not sure I want to set-up such an account. Am I missing something? Why doesn't the Submit button just send the data in the form as in many other websites? http://beagleboard.org/support/RMA -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

I did a search within Gmail like so "label:beagleboard subject:rma " and the second thread, dated 8/11/2014, has what seems like the same problem as I have. It looks like the web page is trying to send my data using whatever email client I have configured the browser with. I tried Internet Explorer and I got the attached dialogue box. This seems to be an uncommon way of designing a web page, at least I don't remember have encountered something like this before. Normally the Submit button justs sends data without using an email client. I don't feel inclined to configure email clients in browsers for security reasons.

[beagleboard] 46 position female stackable header ?
I could use a 46 position female stackable header to make some distance between the BBB and my own PCB. This header is hard to find. There is SSHQ-123-D-08-F-LF made by MLE however it is not for sale - as far as I can tell - in the distributors we already have an account with (Digikey, Mouser, Farnell, Avnet, RS). Does anybody know of any other manufacturer of this part that is available in one of the distributors above? Digikey lists this part as sold by Adafruit but it is out of stock, and it does not appear in the Adafruit website, so I guess it won't be available any time soon. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

I tried a part similar to the one below, which has short legs. The problem is that the legs are not just short but also thin. I thought I had good electrical contact and it turned out I had not. The products with short legs are meant to be soldered to PCBs, they are not meant to be stackble. http://www.mouser.co.uk/ProductDetail/Harwin/M52-5102345/?qs=sGAEpiMZZMs%252bGHln7q6pmzlZUuX%2f53qjz%2fu%2f8%252br%2fpBc%3d -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

Good to know that it works. Putting the connector on the bottom side would suit me too. I would never attempt to solder it myself, as I am not good at that, but I can ask a colleague in the hardware department.

Thanks for the feedback, it is good to know. Hopefully in a few months
the 485 patches will land in the mailine kernel (in the 8250 driver).

Hi Wadi, To compile on the PC for the BB means cross-compiling. There are many ways of doing that, it can be tricky though, just do a Google search or search this email list. I have done it with the BB only when I was playing with buildroot [1] which makes it very easy. When using Debian (or previously Angstrom) on the BB I always used the gcc compiler that comes with them, in other words I did not cross-compile. This is much easier, I just used gcc via putty.

Any chance you could post a picture of a simple drawing of how you connected the 485 driver to the BB (like which pin to which pin and any extra components)? Also could you post your small C test program? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

Maybe I am missing something. I am not an expert in these things, but my current understanding is that what the 485 driver provides extra to what the UART driver does is the automatic switch of the driver enable pin. One test I would suggest, a test I have done myself, is to send and receive data with 485 using the UART driver. In this case the DE/RE needs to be set manually. I do it using echo to /sys/class/gpio. Once that is working well you could start test usinging the 485 driver. You should be able to use your existing rs485_test.c program for that. >> @Alex: I recommend, you read my mail ;-) >> I did not look into the kernel source nor am I sure which driver is used in >> my Setup, >> but the problem is not the "rs485-rts-active-high" flag As Micka and Alex said the 4.1 and 4.4 driver do not have 485 support enabled.

However I would suggest installing a Debian image that comes with a 4.1 kernel rather than using a 4.1 kernel on your current image. Last year I had a problem with some sort of systemd incompatibility with a kernel when I upgraded a kernel whereby the BBB would not boot. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

Great news that it is all working! I wonder, have you seen in the scope how many milliseconds does it take for DE/RE to switch from high to low after the BB finishes writing a block of data to the bus?

No, I am using plain Fedora 21 (not on a virtual machine). The TI Sitara controller on my BBW Rev. A6a is unchanged from when I got it more than 2 years ago. Would it be the case that I need to reflash it or something like that in order to support boot whithout a FAT partition on the microSD card? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

Thanks Robert, only now I understand how it works without FAT. A while back I read the boot chapter of the Sitara controller, and I remember that it is possible to boot from different sources including Ethernet, but had forgotten about the raw mode. I am happy that FAT is not necessary for this reason: some years ago Microsoft sued TomTom because the latter was using FAT in some of its Linux GPS devices. > Try another microSD card or a different usb-microSD-reader...

My (somewhat puzzling) test results follow. All tests were carried out with the image that is in the subject line of this thread. BBW Rev. A6a --- 3 X new Apacer 8 GB cards: none of the 3 cards booted, though they all seemed good otherwise, there was no error reported during flashing or by fsck. These 3 cards were purchased about 2 months ago. In my previous emails I was talking about one of these cards. 1 old Apacer 8 GB card: it booted fine. This card was purchased about 18 months ago. 3 X Kingston 4 GB cards: all 3 booted fine. These are the cards that came with 3 BBW's. 1 Samsung 2 GB card: it booted fine. The puzzling thing with the tests above is this: why does the old Apacer card boots but not the new ones? BBB Rev. B - 3 X new Apacer 8 GB cards: all booted fine. 1 Kingston 4 GB card: it booted fine. I thought that is was necessary to press the Boot button in order to boot from the SD card (instead of eMMC) but that does not seem to be the case with my BBB (which still has the original Angstrom distro in the eMMC). The puzzling thing with the tests above is this: why do the new Apacer 8 GB cards boot with BBB but not BBW? I speculate it is because the Linux kernel is being loaded from U-boot in the eMMC rather than the SD card.

[beagleboard] Issues with FTDI cable on Windows with BBB
I have used putty via USB on Windows on BB White without issue for more than a year. BB White has a FTDI chip. Now I am trying to use the BB Black with the FTDI cable recommended in the BBB manual, however it is not working in 95% of my tries. Once it worked when I had the cable working with Putty in Linux and moved the cable to the Windows PC. By not working I mean nothing I type gets displayed, or occasionally only a few garbage characters appear (for example after I power up the BBB). I am using the latest FTDI drivers for Windows (32 bits), the latest version of putty. I have this problem with both Angstrom and Debian on a BBB rev. B and C. I am configuring putty with 115200 baud. I tried Tera Term but no luck either. Also tried with and without external power supply. On Linux things are well enough with BBB and the FTDI cable (though not as good as with BBW). I also tried a UART-USB bridge with CP210x and it is working well enough on BBB in both Windows and Linux. Any ideas on how to make the recommend FTDI cable work reliably on Windows with BBB? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

Hi Williams, The Device Manager was showing everythin normal, for example when I plugged the cable a COM port appeared, and when I removed it the COM port disappeared. Thanks for the Prolific suggestion. Anyway the problem has been solved. I arrived at work on Friday morning and the FTDI cable was working properly, while it was not working the evening before. What happened in between? I put the computer (Dell Optiplex) in hibernation for the night. I suppose that because that causes power to be cut-off that fixed the issue (while rebooting a few times had not fixed it). But something else fixed the problem as I hibernate the computer every evening. My guess is that uninstalling the FTDI driver did it (plain re-installing did not fix it). As I said before the FTDI driver state was not completely bad because it worked with BBW on the same computer, the problem was only with BBB with the FTDI cable. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

However it would not be out of place (in my opinion) to add a short sentence after this paragraph in section 6.7.2 of the manual: "If you have a uSD card from which you need to boot from, hold the boot button down. On boot, the processor will look for the SPIO0 port first, then uSD on the MMC0 port, followed by USB0 and UART0. In the event there is no uSD card and the eMMC is empty, USB0 or UART0 could be used as the board source." The sentence I suggest could be added would be something like: "Note however that BBB ships with U-Boot on the eMMC configured to boot from the uSD if one is inserted even if the boot button is not pressed." -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

The USB client port on BB White was for me rock solid, always. Then I got a BB Black. For a while the USB client port worked, but then it stopped working, and I lost lots of time trying to get it work, unsuccessfuly . Eventually I gave up on that port altogether. Instead I use a FTDI cable connected to the debug port, an Ethernet cable, and an external power supply. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

[beagleboard] cpuidle
I am looking at ways to reduce power. I have the on-demand cpufreq governor. I am looking now at cpuidle. The AM335x Linux Power Management User Guide [1] says that there are two C-states however I can't find cpuidle on the BBB ([2]) running the [3] kernel. Also I cannot find a Debian package to show cpuidle (the cpupower util is available on Fedora and Ubuntu but seemingly not in Debian). Any suggestions? I wonder if the kernel I am using is not built with cpuidle? Thanks.

I am using now a newish rev. C BBB that I got a few weeks ago. I did what you suggested and pressed the boot button on the BBB to force the BBB to used the uboot in the MicroSD card instead of the uboot in the eMMC. However I still got the same problem as before, i. e., it hangs at the last line of the log with the asterisks moving and the time being incremented.

If I compare my boot log with yours there are a number of differences. One is that the entries about PRU, starting with "pruss-rproc 4a30.pruss: 8 PRU interrupts parsed" appear at 11.6 seconds in my log and at 25.8 seconds in yours. Something is taking a lot of time in your boot. One of the last log entries in my log says "Timed out waiting for device dev-ttyGS0.device." . Any idea about what that is, and why don't you get that error? In any case, I reverted to the bone10 kernel by changing the line about uname_r in /rootfs/boot/uEnv.txt so my BBB boots again. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

Good to know, thanks. I am trying to bring power down, and have been measuring the current going into the BBB through the 5V socket with no USB cable connected. In my first measurement kernel idle was 300 mA. Then I installed cpufreputils and that brought the current down to 230 mA because - unexpectedly - just installing the Debian package changed the CPU mode to "on-demand". Today I managed to bring the current down a further 20 mA (to about 210 mA) by disabling HDMI in boot/uEnv.txt. I am curious now to see how much power cpuidle will save - once I have a kernel with it. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
