[beagleboard] Re: Why dns is not working in this BBB -> laptop hotspot configuration
I use Beaglebone Blue which has no Ethernet port. Yes, internet sharing has many variables, but hotspots often work and if BBB had a typical Wifi manager, there would likely be no issue from the start. There are no tools like telnet or nmcli installed on it. For now, I will try port tunneling via SSH. Thanks Tarmo for your help.

Hello Tarmo. Thanks for your help, host google.com 8.8.8.8 gives ;; connection timed out; no servers could be reached I have lost too much time an attempt to have a working network connection on BB. Firstly, via USB, a known problem. With Linux, it never worked like a normal network. Then, an adapter Ethernet-USB. BB recognized it in maybe 80%, then 20% of times, then never.

Re: [beagleboard] How to set clock in the Beagle bone Black
1) First Find the entire clocking system block diagram and understand how this feeds your subsystem(not easy but required)2) Find some C code in starterware that sets these registers and look at comments and values used in example.After you understand what they are doing adjust your values and measure your results.3)If you can't do that say a prayer and Google for a spreadsheet on TI website that calculates this.4)If you can't do any of above rephrase your question exactly what your system clock is and what registers you are trying to calculate and say 3 prayers someone has time to do this or has done this recently and did all the work you don't want to do and answers the question. The code is out there you just need to dig very hard and spend the time understanding how this is done I've done it its not fun but essential to doing any low level embedded software programming.Good Luck Sent from Yahoo Mail on Android On Mon, Feb 11, 2019 at 8:12 AM, Apeksha gupta wrote: Hello everyone, Hello all, My target is to communicate the two Beagle bone Black via CAN bus.

[beagleboard] BBB booting issue - ** Unrecognized filesystem type **
Hi, I have built code for U-Boot(git://git.denx.de/u-boot.git), Linux(git://github.com/beagleboard/linux.git) and file system(git://github.com/beagleboard/image-builder.git) for BBB. config file used for U-boot is am335x_evm_defconfig, Linux - bb.org_defconfig, rootfs - bb.org-debian-jessie-console-v4.4.conf After building the code, I partition the SD card into boot(fat32) and rootfs(ext4). copy MLO, u-boot.img, zImage and am335x-boneblack.dtb to boot and untar armhf-rootfs-debian-jessie.tar into rootfs. I use uSD card to boot up BBB and I see "** Unrecognized filesystem type **" error in U-boot on executing fatload mmc 0 command. Attached complete logs with printenv. I am not able to understand the issue here since I have not made any changes in the code of any repo. Does process of partitioning of uSD card have any issue? Any inputs would be highly appreciated.

It is a very odd problem, I have loads of ssh logins on BBBs, Raspberry Pis and other systems many of which are remote behind NAT routers and I've never seen an issue like this. What happens is that local (across the LAN) logins always work and the *first* remote login (through the NAT router's port mapping) works but subsequent remote logins fail. As I said we've just set things up so we can do 'remote' logins from the site where the system is, that should let us diagnose what's happening. -- Chris Green · -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
