Testing VSPROG with Freedom board

I’m testing Freedom board with OpenOCD and VSProg following the instruction from this message:

Error:  kinetis auto-detect failed.
Error:  Fail to initialize target.
Error:  Fail to run command: prepare.

To fix this first issue just add this config to kinetis.xml:

<chip name="kl25z128frdm">
<chip_id>0x25151486</chip_id>
<program_mode>js</program_mode>
<app_default>0xFF</app_default>

<uid init="0xFF" bytesize="12" mask="0xFFFFFFFF:0xFFFFFFFF:0xFFFFFFFF" format="%4x%4x%4x"></uid>
</chip>

Now it will report flash error:

This error message “Error: flash is not defined, please define first.” is because I was using ELF instead of binary.
Just convert this ELF to Binary:

$ arm-none-eabi-objcopy -O binary main.elf main.bin

Let us to try again:

Lambendo a criacao (ou o criador)

Desde criança sempre gostei muito de desenhar (creio que quase toda criança gosta) e sempre tive muita facilidade nisso, mas este talento sempre ficou em segundo plano, talvez o lado cientista/pesquisador ofuscou o outro lado.

Esta semana tive a oportunidade de exercer este lado desenhista novamente. Minha esposa pediu que eu criasse uma logomarca para a loja de roupas e aviamentos dela. O nome da loja é Amor de Moça, o nome surgiu a partir de uma flor homonima (amor-de-moça ou, voltando ao lado cientista, apenas: Cosmos bipinnatus).

Inicialmente comecei a desenhar cora√ß√Ķes, ou outras figuras das quais eu pudesse formar as letras A e M, que s√£o as iniciais da loja. Mas nenhum dos modelos da logomarca estavam legais. Foi ent√£o que tive a ideia de usar a propria morfologia da planta “amor-de-mo√ßa” para formar as iniciais da loja.

N√£o deu outra, ficou muito simples e legal:

amordemoca

Para quem tem dificuldades em enxergar formas (por exemplo não consegue ver o C na logo do Carrefour) vai a dica: as letras A e M estão desenhas nas três pétalas superiores da flor.

Se você quiser desenhar flores parecidas com esta use as dicas deste site: http://www.dragoart.com/tuts/3311/1/1/how-to-draw-a-simple-flower.htm

UPDATE: Para ver o resultado da Arte Final acesse www.amordemoca.com

Dica: como listar arquivos num sistema que nao tem o comando ls

Alguns roteadores e outros aparelhos n√£o possuem o comando “ls”, mas felizmente voc√™ consegue resolver este problema com o velho truque do echo:

$ echo *

O fato deles tirarem alguns comandos pode barrar usu√°rios newbies, mas quem conhece mais sabe como contornar os problemas. Outro exemplo √© o caso do Android de alguns celulares que n√£o tem o comando “cp”, mas voc√™ pode usar o comando “cat” para fazer o mesmo papel, pesquise nos comentarios do blog para saber como fazer.

How to debug Freedom Board (FRDM-KL25Z) using OpenOCD

This is a step-by-step to let you debug your board using OpenOCD:

First of all you need to install CMSIS-DAP firmware:
https://acassis.wordpress.com/2013/03/17/changing-frdm-kl25z-boards-firmware-to-become-cmsis-dap-compatible/

You need to install libusb version 1.0:

$ sudo apt-get install libusb-1.0-0-dev

Download and compile OpenOCD with CMSIS-DAP support:

$ git clone https://github.com/TheShed/OpenOCD-CMSIS-DAP.git
$ cd OpenOCD-CMSIS-DAP
$ git checkout -b cmsis origin/cmsis-dap
$ ./bootstrap
$ ./configure --enable-maintainer-mode --enable-cmsis-dap
$ make
$ sudo make install

Time to run OpenOCD:

# openocd -c "interface cmsis-dap" -f tcl/target/kl25.cfg

END...

Now you can debug the FRDM board with openocd normally and even integrated on Eclipse.

That’s all folks, good luck!

UPDATE: After some more tests I noticed the debugging using GDB is not completely functional, then the best approach will be connecting to OpenOCD over telnet at port 4444 and execute the commands to access registers and memory.

Como controlar ponteiro do mouse num computador sem teclado numerico

Como você deve saber saber é possível emular um mouse (mover o cursor) no modo gráfico do Linux usando o teclado numérico, como explicado aqui anteriormente.

Mas e se seu computador (notebook) não tiver teclado numérico?

Felizmente existe um programa que resolve este problema de forma criativa, chama-se keynav.

Instale o keynav com o comando:

$ sudo apt-get install keynav

Em seguida crie o arquivo .keynavrc no diret√≥rio base do seu usuario (no meu caso √© /home/alan) e coloque o conte√ļdo:

Left cut-left
Down cut-down
Up cut-up
Right cut-right
control+Left move-left
control+Down move-down
control+Up move-up
control+Right move-right

Agora você deve executar o keynav (ALT + F2 e digite o comando keynav) e para ativa-lo pressione Ctrl + ; (Control e Ponto e vírgula), você verá uma linha vertical e uma linha horizontal dividindo a tela em quatro áreas, use as teclas direcionais do seu teclado (setinhas) para escolher qual área você quer mover o teclado, vá subdividindo as áreas menores até que o cursamento das linhas fique sobre o local que você deseja mover o mouse, então pressione Enter para clicar.

O bom é que o Linux sempre tem uma solução pra tudo, mas o melhor é nunca esquecer o mouse em casa e nem atualizar o sistema antes de um compromisso importante, pois seu mousepad pode parar de funcionar :-/
