[beagleboard] C: Attempting to mmap an SSD 1306 framebuffer and segfaulting afterwards
I have an SSD 1306 OLED display on my Beaglebone that is configured as a
framebuffer in LInux (3.8.13).
I want to use mmap to get its framebuffer so I can draw on it. The mmap
call does return a pointer, but subsequent operations will segfault.
This is the C code:
#include stdio.h
#include sys/mman.h
#include sys/types.h
#include sys/stat.h
#include fcntl.h
#include unistd.h
#include linux/fb.h
#include sys/ioctl.h
#include wakkomononormalh.h
#include string.h
#include time.h
static char b[1024]; /* Local image buffer */
static struct timespec displaydelay;
int main()
{
struct fb_fix_screeninfo fb_fixed_info; /* Framebuffer information */
int fbfd = 0;
char *fbp = 0;
//Open the file for reading and writing
fbfd = open(/dev/fb0, O_RDWR);
//Map the device to memory
fbp = (char *)mmap(0, fb_fixed_info.smem_len, PROT_READ |
PROT_WRITE,MAP_SHARED
,
fbfd, 0);
if ((int)fbp == -1) { printf(Error: failed to map framebuffer device
to memory./n);
return 4;
}
printf(The framebuffer device was mapped to memory successfully./n);
// Clear screen
memset(b,0,fb_fixed_info.smem_len);
memcpy(fbp,b,screensize);
The code fails at memcpy. I knew I would have a learning curve, but I
have been in circles on this. I thought I dodged a bullet not having to
write kernel drivers for my project, but...
Thanks.

[beagleboard] Re: booting error with BBB [Error: unrecognized/unsupported machine ID (r1 = 0x00000e05).]
Looks like DT file loading before booting is missing. For kernels 3.2 and BBB you should pre-load dtb with u-boot to boot succesfully (or append dtb file to kernel image, but have to CONFIG_ARM_APPENDED_DTB kernel compile option enabled). There is also a possibility that dtb is loaded correctly, but the kernel is too big and when decompresses overwrites dtb - it easy to check if the situation happened in your case with nm tool- no symbol should be loaded above c0f8 for default u-boot config, T. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] cannot ssh over USB Fist use of board
I've tried on Linix and Windows going over the USB with PUTTY. THe BBB disconnects right off. Is there a setup step I've missed? I've looked at 3 tutorials on this and all just say to SSH to 192.168.7.2 port 22 but none give any direction if that does not work. I've Googled this and found not too much as well. The board shows up as a storage device on both machines on Crome browser. I can see the files on the flash as well. Thanks in advance for any help. My cables will be in soon for HDMI to DVI but I wanted to get started.

[beagleboard] Re: learning ARM assy with BBB
hi azzy. i ordered a jtag cable and one logic analyzer. but now i just learned that i must solder jtag header pins onto the bbb. it appears that i can only buy the (samtec) header from digikey for $4. but they only ship by courier for $40! where did u get your headers? thx.dd On Monday, October 28, 2013 5:18:24 PM UTC+2, azzythehillbilly mir wrote: Hi Forum, I have a problem and I am hoping that I kind soul will direct me whereby I am able to help myself get on my feet. This is a bit embarrassing, but here it goes. I got myself a BBB because I want to switch from using MCS-51 processors and the like. I have no formal schooling in processors or electronics. I started working on processors around 1980 when I got hold of an Ohio scientific and later an AppleII+. Later moved to Z80/Z8000/8086/68030 and similar as I started to formally design HW and SW for embedded systems. Never had to bother even with C so have been hacking merrily away with Assembly only. Rarely adding ( with difficulty) bits of code for floating point when my own extended math routines simply would not do. This works for me as I have learned to cram as much functionality as possible into limited resources. I can get working code written and debugged faster than most C coders can. I know nearly zero about Linux//Ubuntu/Fedora. Unless someone has worked on the simple old controllers one might not understand how exciting ( mouth watering even! ) it is to contemplate the peripherals this Sitara 3359 processor provides. I just need to get a jump start. Here is the problem, I want to write code for the Sitara-3359 and learn the nuts and bolts of low level programming (assy). I need some kind of a simple IDE Where I can take control of the processor from reset onwards ( barring un-by passable initializing code prewritten into the processor?). I have been searching all over the net for just that but come up frustrated by the huge number of names/acronyms and all. There are just too many branches to investigate. I get lost every time I try. For the moment I want merely to exercise the Sitara and study its responses, no desire to write any commercial application (with the possible exception of a camera interface for my telescopes). Please kindly somebody point me in the right directions. Once I have the correct IDE set up I can take over and dive into the details. No problem there.

[beagleboard] Re: Strange USB duplicate fragment problem
An interesting addition - If I switch the USB 2 hub for a USB 1.1 Hub, the problem goes away. On Friday, March 7, 2014 6:02:39 PM UTC-8, Terry Hardie wrote: I'm chasing a problem working on support for Bluetooth 4 LE (Low Energy). I have 2 vendor's USB bluetooth receivers. One is a Cambridge Silicon Radio (0a12:0001) and the other is a Broadcom BCM20702A1 (0a5c:21e8). The Broadcom needs a RAM patch to behave properly, but it outside the scope of this problem. BOTH exhibit the same problem (so I seriously doubt it's a problem with the Bluetooth receivers) Both devices are operating in HCI mode. I'm running Ubuntu on my BeagleBone Black. I spent a significant time trying to get Bluez 5.15 to build under the standard Angstrom, but never succeeded (too many dependencies I could not satisfy) I started with the standard eMMC flash image, and have worked from there to the point I'm compiling my own kernels for debugging purposes. I've also built the latest version of Bluez (5.15) The problem is when running a lescan (hcitool lescan) with a LE device in paring mode, which is transmitting a lot of LE Advertising report packets, the HCI drivers eventually loses sync. I've traced it down to a duplicate USB fragment. I've tested these USB receivers under Ubuntu on an Intel machine with the same Bluez 5.15, and the problem is not present. I used usbmon to do a sniff of the USB traffic. Here's a snippet of a correct HCI LE Advertising report event, followed by one where the middle fragment is repeated (frame 1300 is a repeat) (pcap for this attached) No. Time SourceDestination Protocol Length Info 1291 2014-03-07 02:40:16.942573 host 3.1 USB 64 URB_INTERRUPT in 1292 2014-03-07 02:40:16.959480 3.1 host HCI_USB 80 Rcvd Fragment 3e21020100013c30057cf9e115020105 1293 2014-03-07 02:40:16.959624 host 3.1 USB 64 URB_INTERRUPT in 1294 2014-03-07 02:40:16.960449 3.1 host HCI_USB 80 Rcvd Fragment 0d0953636f736368652050524f580319 1295 2014-03-07 02:40:16.960546 host 3.1 USB 64 URB_INTERRUPT in 1296 2014-03-07 02:40:16.961455 3.1 host HCI_EVT 67 Rcvd LE Meta (LE Advertising Report) 0002ae 1297 2014-03-07 02:40:16.961560 host 3.1 USB 64 URB_INTERRUPT in 1298 2014-03-07 02:40:16.981627 3.1 host HCI_USB 80 Rcvd Fragment 3e21020100013c30057cf9e115020105 1299 2014-03-07 02:40:16.981696 host 3.1 USB 64 URB_INTERRUPT in 1300 2014-03-07 02:40:17.002651 3.1 host HCI_USB 80 Rcvd Fragment 3e21020100013c30057cf9e115020105 1301 2014-03-07 02:40:17.002720 host 3.1 USB 64 URB_INTERRUPT in 1302 2014-03-07 02:40:17.003560 3.1 host HCI_USB 80 Rcvd Fragment 0d0953636f736368652050524f580319 1303 2014-03-07 02:40:17.003649 host 3.1 USB 64 URB_INTERRUPT in 1304 2014-03-07 02:40:17.004567 3.1 host HCI_USB 67 Rcvd Fragment 0002b5 I'm really tearing my hair out over this one.

[beagleboard] Re: QNX on BBB
hey doug, thanks for reply. yes I lready did and also found that, lets say ... claim ;) QNX support did not respond yet and the links on their pages on that topic all end dead on foundry 27. first glance it looks that there is something going on but nothing to find after some digging. regarding QNX I wonder in what situation they are at all currently. After being sold to RIM ist there still interest in other embedded market, than automotive and mobile communication? Several emails to sales for quotes and services for technical issues are not been responded. Am Samstag, 8. März 2014 21:32:36 UTC+1 schrieb doog: Have you searched QNX for what they support?
