**** BEGIN LOGGING AT Thu Nov 11 09:52:15 2021 Nov 11 14:49:07 Hi Good Morning. We are using sleep-wakeup function. If Application is in idle, put debian into sleep, then a trigger to wakeup. But I found that after wakeup, the usb device is not functional. ls /dev/sd* returns: ls: cannot access '/dev/sd*': No such file or directory even with usb is unplugged and plugged in. Is there some command to bring back Nov 11 14:49:07 the usb device into life? Nov 11 15:26:02 that'll depend on what's actually going wrong Nov 11 15:26:19 i.e. whether it's a problem with the usb device or a bug in a driver Nov 11 15:56:38 I found that using suspend through systemctl, the usb device is available for mounting /umounting. Nov 11 18:57:47 Hi All, This is a request to get information about the beagle community. I have few years of experience of using Beaglebone Black doing low level software for linux and writing firmwares. Could someone point me to the right path. Nov 11 19:05:23 Is BBB having the same inventory issues the rest of the industry is experiencing Nov 11 19:06:56 crikets!? Nov 11 20:31:02 Hi guys Nov 11 20:31:48 wondering if beaglebone is supported by intel movidius neural compute stick Nov 11 20:32:07 i can't find any tutorial that talk about it , any idea please ? Nov 11 20:33:44 Joseph, it's just a usb device, i guess it depends if Intel released support for it in source form or x86 binaries.. Nov 11 20:36:13 rcn-ee thanks for the answer ... Actually, even in movidius official github website, they are talking about Raspberry PI Nov 11 20:36:39 quick search in the net, same thing , nothing is clear about beaglebone Nov 11 20:36:48 well it's linux... Nov 11 20:36:55 I know movidius usually has only 64-bit binaries. I found a couple external devices that hold this chip. Nov 11 20:37:19 even, the Raspberry install procedure can not be done on beaglebone ! same file doesn't exists Nov 11 20:37:36 what are their install directions say? Nov 11 20:37:46 https://movidius.github.io/ncsdk/install.html Nov 11 20:38:28 DepthAI did this too w/ the intel modivius chip along w/ a cam. Nov 11 20:38:56 if you can help me guys to find some useful turorial about installing movidius on beaglebone, i will be grateful Nov 11 20:42:51 Joseph, BBB get's stuck here: https://github.com/movidius/ncsdk/blob/ncsdk2/install.sh#L55 the "64bit only" above that looks bad.. Nov 11 20:43:50 so, no chance for beaglebone black ... what about beaglebone gree ? Nov 11 20:43:52 green ? Nov 11 20:44:21 rcn-ee Nov 11 20:44:35 Joseph, it's all the same hardware, when i say BBB i'm talking about am335x.... Nov 11 20:45:39 Joseph, i just patched out that test: https://paste.debian.net/1219178/ it's still running on buster.. let's see where it fails.. Nov 11 20:48:22 Hello...if you are into neural networks and porting to the BBB/BBAI, look at this idea I got to work: https://www.hackster.io/functt/tensorflow-lite-tensorflow-and-the-bbai-34f793 . This works on the 32-bit processors on the BBB/AI/Green/Green Wireless and so on. am335x or am5729! Nov 11 20:48:24 But... Nov 11 20:49:45 You may want to add a LCD Screen and have it work like w/ graphics instead of using the OS. Nov 11 20:50:24 sorry for interrupting. I just figured it could be helpful. Nov 11 20:51:05 yeah rcn-ee ... thanks set_, however the idea of my project is to use BB combined with movidius Nov 11 20:51:47 i think that i will need to get Raspberry Pi 3:(   , not sure if there is an alternative solution to combine the power of BB and acceleration of movidius Nov 11 20:52:41 Joseph, which OS version are you running, On Buster it's installing everything with my one patch.. Nov 11 20:54:11 i'm using Debian GNU/Linux 10 (buster) release 10 Nov 11 20:54:16 rcn-ee Nov 11 20:54:44 I'm still waiting for man-db to finish, what error are you getting on the console? Nov 11 20:57:51 Sorry for interjecting again. I am interested in this subject b/c of a OAK-D camera that was purchased on my end. I have it and it works w/ 64-bit only so far. I cannot get it to produce the correct install for whatever reasons. Nov 11 21:00:18 Maybe if you guys get this to work, I will have hope again. Nov 11 21:00:33 there git repo is broken: Could not find a version that satisfies the requirement tensorflow==1.11.0 (from versions: 1.12.0, 1.13.1, 1.14.0) Nov 11 21:01:08 DepthAI? Nov 11 21:02:34 https://github.com/movidius/ncsdk/blob/ncsdk2/install.sh#L432 Nov 11 21:02:39 i just overrode it... Nov 11 21:06:20 Joseph, looks pretty dead: https://github.com/movidius/ncsdk/commits/ncsdk2 i hope you had the hardware first and decided to use it... ;) Nov 11 21:12:03 rcn-ee , do you advice me to switch with Raspberry Pi 3 as described in here https://movidius.github.io/ncsdk/install.html ???? Nov 11 21:13:23 Just run it on the am335x/bbb, with the patch i posted.. Nov 12 00:54:11 Hello, Can anyone please help me find right cellular modem with cape for Australia for BBB? Nov 12 01:15:07 The closest I found is the SDR Cape but who knows? It may be out there somewhere. I have not seen a cell modem Cape yet. Nov 12 01:16:02 What pins do you need for cell modem stuff, i.e. I/O, UART, i2c? Nov 12 01:17:19 Here is that Cape, https://www.seeedstudio.com/KiwiSDR-Board-p-2723.html , in case you see something on it you can use. Nov 12 01:22:09 I will use I/O that will be much easier Nov 12 01:26:10 One can use just I/O on the BBB for cellular data? Nice. Nov 12 01:27:21 I figured you would need at least UART to handle transmission from the am335x to the Cape or module. Nov 12 01:27:56 3.3v cellular module may work...if you have your p's and q's in order. Nov 12 01:29:36 Guest828: Look here... https://www.adafruit.com/product/3147?gclid=EAIaIQobChMIttuw-dWR9AIVUnxvBB2dvgJ-EAQYBSABEgKvw_D_BwE Nov 12 01:29:49 That may work. I am still researchin' this idea real quickly. Nov 12 01:32:05 It is 5v. Blah. But...one can use different circuits to handle the dc/dc conversion. Nov 12 01:32:27 And...UART is usually done in 3.3v anyway. Nov 12 01:33:44 I will check that out. Thank you:) Nov 12 01:33:46 I think that is as cheap as they come. Nov 12 01:33:52 You are welcome. Nov 12 01:34:43 It says "microcontrollers" from 3 to 5v. BBB is in! Nov 12 01:35:11 You can use the BBB hopefully. I am sure there is a large datasheet somewhere that has better ideas than I can provide. Nov 12 01:42:13 Guest828: I also found some from Digi and the XBee people. Nov 12 01:44:16 I need cellular modem with wide frequency range so that I don't have to stick to one service provider Nov 12 01:44:32 Do not get that one...it says it cannot be used in the AUS. Nov 12 01:44:44 There was a tip at the end of the info. Nov 12 01:46:36 Guest828: I found this neat set up for AUS in mouser.com: https://au.mouser.com/c/i/embedded-solutions/wireless-rf-modules/?operating+supply+voltage=3.3+V Nov 12 01:46:44 They must provide a service in that country. Nov 12 01:49:47 Anyway...I found some from Digi. They have XBee 3G, LTE-M embedded modules, and some more. Nov 12 01:50:28 Neat. I have to get one for cellular now. Thank you...I am such a sucker for making things work properly. Nov 12 01:50:59 Guest828: What bands are allowed in AUS? Nov 12 01:51:48 https://mobilenetworkguide.com.au/australian_mobile_phone_frequencies.html#:~:text=In%20Australia%20the%20current%20mobile,the%20850%20and%20900%20bands. Nov 12 01:52:04 Oh. Y'all have many. Okay. Nov 12 01:53:04 3G` Nov 12 01:53:11 I see... Nov 12 01:53:26 So, it was 900/1800 for a long time. Nov 12 01:53:59 Are you looking for 2100MHz? Nov 12 01:54:27 Or, like you said, one that has many different available frequencies? Nov 12 01:55:28 Forget it. You guys got everything. Nov 12 01:55:50 I was thinking you all had a severe shortage of frequencies and bands available. Blah. Nov 12 01:56:32 Towers! Nov 12 01:57:26 in '97, the market was different. Way different. No market. Nov 12 01:57:27 Ha. Nov 12 01:57:57 Now, it is like a common courtesy to text a person, i.e. even when they are next door. Ha. Nov 12 02:02:09 It would be better to have as many frequencies as possible so that I can use it in other countries too. Nov 12 02:02:19 oh. got it. Nov 12 02:02:40 I highly appreciate your help Nov 12 02:02:50 Well, I wish you luck. That 3.3v au.mouser.com site has many items for selling. I think making one would be easy enough too. Nov 12 02:03:39 That sim card is probably tricky...well. I think the GPS/Cellular/Freq. card is the most of the cost. Nov 12 02:05:45 I met that guy once who made Nextel. It was an older co. in the US. He ran for senator and won. He is still around saying this and that on our laws. Nov 12 02:07:31 Sorry. Mark Warner is his name. He is a senator for VA now. he started/owned some telecommunications co. Nov 12 02:09:46 Anyway...so. Guest828: Would you like me to find one w/ many different frequencies? Nov 12 02:09:53 Bored over here. Nov 12 02:12:59 Yay! Nov 12 02:23:00 The XBee modem can handle AT commands and can be controlled via SPI. The BBB has SPI. Nov 12 02:23:43 I wonder what the source looks like for a SPI command along w/ AT commands in Python...hmm. Nov 12 02:28:32 Dang...one would need a TCP source, SIM source, Modem source, Client source, and then the source to handle a SMS/email sending. Nov 12 02:29:10 I hope Guest828 knows his way around cellular tech. That is difficult biz. **** ENDING LOGGING AT Fri Nov 12 02:59:56 2021
