Re: [beagleboard] Re: Disabling/enabling the USB slave interface dynamically
I'm using my c-program that creates files. It uses the the USB-mass storage device that comes with the BBB which is created by /opt/scripts/boot/am335x_evm.sh (so, in that sense, you could say I use a script). I've mounted the disc-image-file it uses, so my application simply writes its files to that device, for the host PC to copy. The BBB with my application is a measuring device which produces result files (in the same way as a digital camera). It would nice to be able to upload these files to a PC via USB. Scp could be a solution but I don't have control over the host PC, in the sence that I don't want to install programs on it. The PC usually belongs to somebody else. Simply put, I want to the ability to connect to any PC, have my application to create files on the BBB and then letting the owner of the PC to upload them to his domain. Another solution is to unplug-reinsert the cable after every measurement. That's where I stand today ...but it's not pretty. I feel I'm so close: I only need my application to toggle the USB device off/on, so the host will behave as if it was unplugged/reinserted, and update its file info. But I don't know how. I have difficulties understanding the am335x_evm-script and it seems to be run once, at startup. Isn't there an easy way of turning the USB-mass- storage-device on and off from an application? Yes, I have been thinking of buying a mechanical relay, controlled by a gpio, to unplug the cable from my application. That would probably do the job, but it feels awkward.

[beagleboard] Re: Getting started: Step #2 and #3 just dont work on Windows 10 (or 8, or 7)
Actually, on the Windows 7 the symptoms were a bit different. It was an old machine with only 4GB RAM and the PC seemed to be overloaded during the installation with locked screen for most of the time. So the only similarity I can be sure of is the URL not responding. Anyhow, I think I've found problem on Window 10: It won't install drivers lacking valid MS-signature. It doesn't tell you that, it simply tells you that installlation failed (thank you Microsoft). I turned off this signature checking and now it work (even step #3). So I'm back on track again. Ther must be more rookies having this problem out there: Try google https://youtu.be/71YAIw7_-kg to disable this feature. Or, BBB: Get this signature from MS. It seems to be a matter of $99 to get it. The 5 minutes needed to get up and started (according to your purchase text) has grown to more than 5 hrs...

[beagleboard] Disabling/enabling the USB slave interface dynamically
I share files created on the BBB with a USB host (e.g. Windows PC) using the USB mass storage device (almost like a digital camera). It works fine except for one point: Whenever a new file is created by BBB, I need to unplug-reinsert the USB cable in order for the file to become visible in the host (master). It would be nice if I could have my BBB-application to "unplug" the USB whenever it creates new files, and then reenable it again, forcing the host to update its file info. But how do I do that? Is it possible to easily disable/enable the slave USB interface on the go? Or even better, only the mass storage device, leaving the other USB functions running. Googling the issue I find a lot of solutions on how to disable it permanently, editing the am335x_evm.sh, but that's not what I want. I'm running a recent Debian Stretch from the BBB distribution web page. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

Re: [beagleboard] Enabling SPI in BBB, Debian Stretch
Thank you Robert, That did the trick. However, it has the side-effect of turning my display all black. I use a Newhaven display cape and according to its User Guide, there should be no conflict for these SPI-pins. (http://www.newhavendisplay.com/userguides/NHD-7.0CTP-CAPE_User_Guide.pdf) So I had a look at the assigned pins in /sys/kernel/debug/pinctrl/44e10800.pinmux/pingroups and see that following group is added (using diff): > group: pinmux_bb_spi0_pins > pin 84 (PIN84) > pin 85 (PIN85) > pin 86 (PIN86) > pin 87 (PIN87) which seems in order, but following groups were removed: < group: pinmux_bb_lcd_pwm_backlight_pins < pin 18 (PIN18) < group: pinmux_bb_lcd_lcd_pins < pin 40 (PIN40) < pin 41 (PIN41) < pin 42 (PIN42) < pin 43 (PIN43) < pin 44 (PIN44) < pin 45 (PIN45) < pin 46 (PIN46) < pin 47 (PIN47) < pin 48 (PIN48) < pin 49 (PIN49) < pin 50 (PIN50) < pin 51 (PIN51) < pin 52 (PIN52) < pin 53 (PIN53) < pin 54 (PIN54) < pin 55 (PIN55) < pin 15 (PIN15) < pin 14 (PIN14) < pin 13 (PIN13) < pin 12 (PIN12) < pin 11 (PIN11) < pin 10 (PIN10) < pin 9 (PIN9) < pin 8 (PIN8) < pin 56 (PIN56) < pin 57 (PIN57) < pin 58 (PIN58) < pin 59 (PIN59) < pin 35 (PIN35) < group: pinmux_edt_ft5x06_pins < pin 105 (PIN105) I don't know about the last group (PIN105) but the other two groups most certainly affect the display function. I haven't seen the corresponding .dts-file for BB-SPIDEV0-00A0.dtbo, but I tried making my own that should not touch these pins: Still, the same result (same pin groups are removed). There seems to be some mechanism that disables the display pins when adding an overlay to the uEnv.txt. Robert, as an expert in BBB, do you have answer to this? Best regards, Jon Lundström.

[beagleboard] Enabling SPI in BBB, Debian Stretch
I'm trying to enable SPI on my BBB but constantly fail following the advises I find in the forums. It seems like echoing anything into /sys/devices/platform/bone_capemgr/slots is obsolete. Instead I should set up in /boot/uEnv.txt, but how? What should I add in that file? I've tried: cape_enable=bone_capemgr.enable_partno=BB-SPIDEV0 or: optargs=quiet drm.debug=7 capemgr.enable_partno=BB-SPI0-01 ...but I still don't get anything named spi* under /dev/ (yes, I've rebooted) ls -l /dev/spi* ls: cannot access '/dev/spi*': No such file or directory I would be happy with only one SPI, like SPI0 so I wouldn't have to bother with disabling HDMI.
