I was getting this error message:
build/tools/apriori/prelinkmap.c(168): library 'libblablabla.so' not in prelink map
To solve it just edit the file build/core/prelink-linux-arm.map and add:
libblablabla.so 0x99000000

Error:
drivers/mtd/nand/mxc_nd2.c: In function 'mxcnd_probe': drivers/mtd/nand/mxc_nd2.c:1233: error: 'NFC_BASE_ADDR_AXI' undeclared (first use in this function) drivers/mtd/nand/mxc_nd2.c:1233: error: (Each undeclared identifier is reported only once drivers/mtd/nand/mxc_nd2.c:1233: error: for each function it appears in.)
Solution:
Edit drivers/mtd/nand/mxc_nd2.h and rename NFC_BASE_ADDR_AXI to MX51_NFC_BASE_ADDR_AXI
Hoje resolvi clicar no link do servidor HTTP existente no meu modem ADSL da D-Link:
http://www.acme.com/software/micro_httpd/
É muito interessante ver que ele foi escrito em apenas 200 linhas em C.
Ok, em python você consegue fazer em 5 linhas ou menos, mas isso não conta.
Definitely we don’t have good Linux race games with force feedback support. I don’t know who is the guilt: users, game companies, Linux distros companies, developers?
Until now only VDrift has force feedback support, but its graphics are very bad, even TORCS has better graphics. There is also Racer (racer.nl) with force feedback support and nearly professional graphics, but you cannot find a recent binary version to Linux, only Windows, they even suggest user to test it using Wine (oh my gosh).
So, lets compiling VDrift for Linux, after downloading from repository you need to use “scons” to compile it. After some compilation errors I updated glew to version 1.5.5 and everything worked.
To compile VDrift with FF support execute:
scons force_feedback=1
Then edit ~/.vdrift/VDrift.conf and add your steer wheel details (Logitech Momo in my case):
[ joystick ] calibrated = false ff_device = /dev/input/by-id/usb-Logitech_Logitech_MOMO_Racing-event-joystick ff_gain = 3.608330 ff_invert = false hgateshifter = false two_hundred = false type = wheel
It is not perfect, but it is all we have right now 😦
Enquanto o modem DLink 2026B que comprei pela internet não chega, estou me virando com o SpeedStream que meu amigo Hamilton me emprestou. Este modem estava funcionando muito bem, até o momento que resolvi instalar o Skype. Por algum motivo o LED de atividade começa a piscar sem parar até o momento que ele reinicia (todos os LEDs acendem).
Segui várias dicas que encontrei na internet, mas a unica que funcionou foi esta:
DESABILITAR o UPnP
DESABILITAR o TIME CLIENT
Esta dica foi dada pelo usuário carlosmarckk no forum da skype:

Kudos para o carlosmarckk, muito obrigado!

Maybe you can remember an old post I explained how to create patches using CVS:
https://acassis.wordpress.com/2009/07/14/creating-diff-using-cvs/
Today I needed create patches on CVS again, and it worked fine to me:
$ cvs diff -up > example.patch
I discovered NuttX RTOS few weeks ago (thanks Marcelo Barros) and I like it very much, then I decided to test it on Olimex LPC2378-STK.
NuttX is a very small foot-print RTOS (starting about 20KB) which follows the POSIX and ANSI API, this means you can port your Linux application to run on this RTOS easily. I know FreeRTOS is even smaller and have a bigger community, but NuttX has advantage for follow the *nix APIs and recreate the Linux devices structure.
The only concern about it is the license, it is BSD. I never contributed for a BSD project (For As Long As I Can Recall). Then I need to get used with this idea.
Let start downloading the NuttX source code:
The current stable version is 5.17, but I prefer always using the repository version, so lets download it:
$ svn co https://nuttx.svn.sourceforge.net/svnroot/nuttx nuttx
Now is time to download the cross-compiler (toolchain). I’m using the CodeSourcery toolchain:
https://sourcery.mentor.com/sgpp/lite/arm/portal/package7815/public/arm-none-eabi/arm-2010.09-51-arm-none-eabi.bin
Download and install it:
$ chmod a+x arm-2010.09-51-arm-none-eabi.bin $ ./arm-2010.09-51-arm-none-eabi.bin
I installed it on /opt/cs/sourcelite but feel free to install it any place, just remember to place the corresponding binary directory (i.e.: /opt/cs/sourcelite/bin) in our PATH.
I selected the Minimum installation since I don’t want to use its IDE.
Now we need to modify some files to get NuttX compiled with CS toolchain:
Edit file nuttx/configs/olimex-lpc2378/nsh/defconfig and change the toolchain to CodeSourcery on Linux (Note: currently it is already defined):
CONFIG_OLIMEX_LPC2378_CODESOURCERYW=n CONFIG_OLIMEX_LPC2378_CODESOURCERYL=y CONFIG_OLIMEX_LPC2378_DEVKITARM=n CONFIG_OLIMEX_LPC2378_BUILDROOT=n
Make sure to include the toolchain in the PATH:
$ export PATH=/opt/cs/sourcelite/bin:$PATH
Now configure NuttX to compile the NSH shell using LPC2378 configuration:
$ cd tools $ ./configure.sh olimex-lpc2378/nsh $ make
It will create two files: nuttx and nuttx.bin. The first is the ELF binary and the second is the firmware binary.
We can see more information about the ELF file using the size command:
$ size nuttx BFD: nuttx: warning: sh_link not set for section `.ARM.exidx' text data bss dec hex filename 78228 368 2332 80928 13c20 nuttx
Now we need to flash the firmware (nuttx.bin) inside Olimex-LPC2378-STK. We can use OpenOCD to flash the firmware. I used Amontec JTAGKey for flash programming.
Run OpenOCD, it will open a telnet daemon on port 4444.
Note: nuttx.bin needs to be in the same directory where you ran openocd.
# openocd -f jtagkey.cfg -f lpc2378.cfg
Connect to OpenOCD’s telnet:
$ telnet 127.0.0.1 4444
Execute these commands to erase the flash and write the firmware on it:
> reset run > reset halt > flash erase_sector 0 0 26 > flash write_bank 0 nuttx.bin 0
Connect a serial cable on LPC2378-STK port1 (RS232_0) to your computer and configure minicom to 9600 8n1. You should see the NuttShell (NSH) prompt “nsh>”.
