A trick to show Debug messages only in the current file

This trick can be used to avoid showing annoying debug message from all drivers and subsystems supported by NuttX:

#include <nuttx/config.h>

/* Trick to get DEBUG messages only in this file */
#define CONFIG_DEBUG 1
#define CONFIG_DEBUG_VERBOSE 1
#define CONFIG_DEBUG_I2C 1

#include <debug.h>
#include <sys/types.h>
#include <stdint.h>
#include <stdbool.h>
#include <errno.h>

It is very important to put the “defines CONFIG_DEBUG*” only AFTER the include nuttx/config.h and BEFORE the include debug.h.

Thanks Greg Nutt for this nice tip!

Debugging NuttX on Atmel SAM L21 microcontroller with J-Link programmer

Run JLink GDB server this way:

$ JLinkGDBServer -device ATSAML21J18 -if SWD

Execute GDB passing the ELF file:

$ arm-none-eabi-gdb nuttx

Connect to GDB server:

(gdb) target remote localhost:2331
Remote debugging using localhost:2331
0xfffffffe in ?? ()

Reset, load, add breakpoint and continue:

(gdb) monitor reset

(gdb) load nuttx

Fix the Ubuntu blinking mouse cursor

If you just installed Ubuntu 14.4 LTS and you get annoyed by mouse cursor blinking all the time, then you get fix it disabling the “Unknown Display”.

Open the Unity Control Center clicking in the gear icon at application bar or executing the command “unity-control-center –overview”.

Then click in the “Displays” icon and in the new screen click on “Unknown Display” and change it from “ON” to “OFF” to disable it.

Finally click on Apply and the cursor will stop to blink.

Using the Nintendo Wii Nunchuk Joystick in the STM32F4Discovery running NuttX

I created a simple NuttX sensor driver (I will implement a joystick driver and send to NuttX mainline) to use Nunchuk Joystick with STM32F4Discovery running NuttX.

We have two options to see the NuttX serial console on STM32F4Discovery board: 1) Connect a USB/Serial dongle to UART pins or 2) Use the “usbnsh” configuration to get the serial console in the MicroUSB port (CN5).

I opted to use the UART pins because I have many USB/Serial dongle here.

The NuttX serial console for STM32F4Discovery board is on UART2:

PIN   |   FUNCTION
------------------
PA2   |    TX
PA3   |    RX

Then all I need to do is to connect the dongle GND signal to board GND, RX signal to PA2 pin (TX) and TX signal to PA3 pin (RX).

After getting the NuttX running in the board I connected a Nunchuk receptacle connector (I cut it from a Wii Mote damaged board) to STM32F4Discovery.

I’m using I2C 1 in the pins PB7 and PB8:

/* I2C config to use with Nunchuk PB7 (SDA) and PB8 (SCL) */

#define GPIO_I2C1_SCL  GPIO_I2C1_SCL_2
#define GPIO_I2C1_SDA  GPIO_I2C1_SDA_1

This is the Nunchuk to STM32F4Discovery wiring connection:

---------------------------------
  Nunchuk  |   STM32F4Discovery
-----------|---------------------
     1     |       PB7
     2     |       NC
     3     |       3V
     4     |       PB8
     5     |       NC
     6     |       GND

This is the Nunchuk pinout:
nunchuk_pinout

The Nunchuk can be detected at I2C address 0x52. And to initialize it you need to write “0x40 0x00” (write 0x00 in the register 0x40).

This is the command used to debug the reading of data:

nsh> dd if=/dev/nunchuk0 of=/dev/null bs=6 count=1 
 X: 114 | Y: 126 | Buttons: 3 
nsh>

More than one thousands words:
nunchuk_connection

JTAG 20 pins to SWD 10 pins cable adapter

This is how I created a JTAG to SWD cable adapter/converter:

   JTAG   |   SWD  
--------------------
    1     |    1 
    7     |    2
    9     |    4
   20     |    5

Don’t get fooled by git

It is strange, I “git add” a directory and then rename a file inside it to another name and pushed it to github. Then when cloned again from github noticed the rename file wasn’t there.

So you need to pay attention when renaming files…

Then I order to avoid mistake I decided to document how I’m doing things:

$ git clone https://github.com/getfilament/NuttX-L21.git
...
$ git fetch origin master
$ git merge origin/master
...
Modify/Git Add if new file/
...
$ git push        ... or ...      $ git push origin master
...

That is it!

Flashing NuttX on SAML21 microcontroller

I was trying to use OpenOCD and STLink-v2 to flash a board powered by Atmel SAML21 microcontroller, using this openocd.cfg:

# SAML21 X Pro Target

# Using stlink as SWD programmer
source [find interface/stlink-v2.cfg]

# SWD as transport
transport select hla_swd

# Use SAML21 target
set WORKAREASIZE 0x4000
source [find target/at91samdXX.cfg]

But OpenOCD was reporting this error:

Warn : UNEXPECTED idcode: 0x0bc11477
Error: expected 1 of 1: 0x4ba00477

Then I modified at91samdXX.cfg replacing 0x4ba00477 by 0x0bc11477, but the “reset halt” command was failing.

Then I decided to use a J-Link programmer:

$ sudo JLinkExe

J-Link also detected the same idcode: 0x0bc11477 (I think this is the ID for Cortex-M0 microcontroller), then OpenOCD is correct. Using J-Link I got nuttx.bin flashed correctly.

Now I need to investigate about the STLink-v2 reset issue.

Modifying the original NOR Flash layer of IP Camera to support a big uncompressed kernel

The original VStarCAM H6837WI NOR flash reserves only 1.5MiB for Kernel, 4MiB for main rootfs and about 2.3MiB for IPCamFS.

Then I decided to increase the kernel size to 3.3MiB, the my layout becomes:

[ 0.870000] 0x000000000000-0x000000030000 : "ARMboot"
[ 0.880000] 0x000000030000-0x000000390000 : "Kernel"
[ 0.890000] 0x000000390000-0x000000770000 : "RootFS"
[ 0.900000] 0x000000770000-0x0000007f0000 : "IpcamFS"
[ 0.910000] 0x0000007f0000-0x000000800000 : "param"

These are the mtd partition size:

# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00030000 00010000 "ARMboot"
mtd1: 00360000 00010000 "Kernel"
mtd2: 003e0000 00010000 "RootFS"
mtd3: 00080000 00010000 "IpcamFS"
mtd4: 00010000 00010000 "param"

This is the command I used to create the decompressed kernel uImage :

$ mkimage -A arm -O linux -T kernel -C none -a 0x50C08000 -e 0x50C08000 -n '2.6.24ssl' -d arch/arm/boot/Image uImage
Image Name:   2.6.24ssl
Created:      Tue Jun  2 17:21:23 2015
Image Type:   ARM Linux Kernel Image (uncompressed)
Data Size:    2737056 Bytes = 2672.91 kB = 2.61 MB
Load Address: 0x50C08000
Entry Point:  0x50C08000

This is the bootargs to map this new layout:

bootargs=mtdparts=physmap-flash.0:192k(ARMboot)ro,3456k(Kernel),3968k(RootFS),512k(IpcamFS),-(param) mem=20M console=ttyS0,115200n8 init=/sbin/init root=/dev/mtdblock2

Flashing Kernel:

object$ loady
object$ erase 0x10030000 0x1038FFFF
object$ cp.b 0x50C07FC0 0x10030000 0x360000

Flashing RootFS:

object$ erase 0x10390000 0x1076FFFF
object$ loady
object$ cp.b 0x50C07FC0 0x10390000 0x200000
object$ loady
object$ cp.b 0x50C07FC0 0x10590000 0x1E0000

Flashing IpcamFS:

object$ loady
object$ erase 0x10770000 0x107EFFFF
object$ cp.b 0x50C07FC0 0x10770000 0x80000

Flashing param:

object$ loady
object$ protect off 1:134 
object$ erase 0x107F0000 0x107FFFFF
object$ cp.b 0x50C07FC0 0x107F0000 0x10000
object$ protect on 1:134

Now I can boot but I’m facing a segmentation fault:
