OpenOCD bat file details

 Created dropbox dir with openocd bat files as backup

 Goal: get openocd working on my laptop

 Status: 
   Trying to change the lab PC openocd bat files so openocd can flash from a fixed location


Questions:

• Can the arm sectors be unlocked from OpenOCD or just via SAM-BA?
• yes
• flash protect 0 0 15 off
• Can .cfg files on Lab PC be used on Laptop
• So far - no, but lab pc can be in local directory
• lab pc is openOCD 3 and Laptop openOCD 4
  

Bat files examined in detail:

openocd - FLASH.bat

.cfg files will be copied here as backup, but real files used.

Not currently used:
arm-elf-objcopy
-->Copies a binary file, possibly transforming it in the process
Option
--gap-fill               Fill gaps between sections with

Files used:
D:\AA_local\eclipseWork\forte_lms_neu\bin\lms\src\forte 

-- created by ???
D:\AA_local\eclipseWork\forte_lms_neu\bin\lms\src\forte.bin

-- created from forte file

arm-elf-size D:\AA_local\eclipseWork\forte_lms_neu\bin\lms\src\forte

To see size of data downloaded to know if too big for LMS 

openocd.exe

Options:

-v display version

-f flash

C:\openocd\trunk3\src\openocd.exe -v

C:\openocd\trunk3\src\openocd.exe -f C:\openocd\trunk3\testing\examples\SAM7S256Test\prj\SAM7S256_flash.cfg -d2

.cfg files 

Here are the real instructions to open 

Feb. 13,14 Code Review 1

Code Review was done via SkyPe.
The comments have been organized by topics, not time.


cMake compile of hg + 1103 code

[10:37:33 PM] Carolyn Oates: for cmake you copied everything from arch/ecos/lms unchanged into modules'/lms?

[10:37:40 PM] Alois Zoitl: nope

[10:37:51 PM] Alois Zoitl: I moved it to modules/lms/lms_hw

[10:38:04 PM] Alois Zoitl: I thought a little seperation might be nice

[10:38:09 PM] Carolyn Oates: No cmake...txt changes

[10:38:28 PM] Alois Zoitl: yes added subdirectory and added additional cmake.txt there

[11:07:23 PM] Carolyn Oates: lms_main goes in plain lms dir?

[11:11:20 PM] Carolyn Oates: filenames should all be lower case?

[11:11:27 PM] Alois Zoitl: yes and yes

[11:11:46 PM] Carolyn Oates: So I need to rename Buttons to buttons

[11:22:01 PM] Carolyn Oates: Do the .h files need to be listed in the CMakeLists.txt file?

[11:22:30 PM] Alois Zoitl: I'm not sure. However for building distributins afterwards it would be better I gues

[11:27:10 PM] Carolyn Oates: Does your code have #include "../../arch/ecos/lms/buttons.h" in it?

[11:27:38 PM] Alois Zoitl: no changed it to "lms_hw/buttons.h"

2/14 note: avr_ctl, buttons, sensors now start with lowercase letter and end with cpp
 Other files must stay .c files

////
follow the coding rules
10:15:31 PM] Alois Zoitl: How about having a baseclass for all sensor port fbs e.g. CSensorPortFB : public CFunctionBlock{...};
[10:15:43 PM] Alois Zoitl: and put there the port management


[10:26:17 PM] Alois Zoitl: please don't start functions with uppercase letters


////


2/14 note: LED on/off and initialization are ready inline functions in the FB.
Need to change lms_main to use these functions.

[11:44:04 PM] Alois Zoitl: I'll be gone for today. Had a look on the i2c files in ecos they are somewhat different. so we should currently stay with the ones we have.

10:23:46 PM] Carolyn Oates: LMS_LTLED_INIT and LMS_RS485 are init functions

[10:24:06 PM] Carolyn Oates: LMS_LT_LED_ON /OFF are led fns that do something

[10:25:30 PM] Carolyn Oates: The LMS_ functions should go in an LED.h except LMS_RS485... its initialized the Port in general.

[10:26:24 PM] Carolyn Oates: so lms_RsvSensorPort  and LMS_RS485_PORT_INIT() belong together

[10:26:45 PM] Alois Zoitl: there should also be a unrsv function

10:28:58 PM] Alois Zoitl: it is just needed to support the an INIT-

[10:30:42 PM] Alois Zoitl: no it means that you want to deinitialize the FB

[10:30:48 PM] Alois Zoitl: i.e., QI false

[11:39:46 PM] Carolyn Oates: isnt this backwards?

[11:39:48 PM] Carolyn Oates:   if (pa_nInputPortPin < NXT_SENSOR_PORTS_MAX)

    return PORT_NUMBER_UNDEFINED; // Port doesn't exist

[11:40:43 PM] Alois Zoitl: yep

Open Question: 
2/14 latest comment - avr_ctl content is ok.

Anything else in avr code other than sensor code that is:

[10:16:44 PM] Alois Zoitl: currently your separation feels for me not very natural as it seperates things that belong together
[10:16:48 PM] Alois Zoitl: e.g., avr code
[10:16:56 PM] Alois Zoitl: and isolates other stuff




What is the event sent to the application?
[10:35:52 PM] Alois Zoitl: there is the nice clean recsource feature we used in the demo with the students   


[10:55:52 PM] Carolyn Oates: Off the top of your head - any idea what misc.h an miscxx.c are?
[10:58:12 PM] Carolyn Oates: Asked without looking... Having looked I think its Alex's and Dominik's debug via usb print.


[11:05:57 PM] Carolyn Oates: Did you compile with or without boot blinky?
[11:06:18 PM] Alois Zoitl: without but that should't be an issue afik
[11:06:51 PM] Carolyn Oates: Does it compile files not needed?

(Short-term) Future Task (Wishlist)

Very near future: SIGCSE
Before SIGCSE work out what is feasible and what could be a problem:


Racket on KIPR BotBall
- Want to demo to Racket group March 9 
Greenfoot connection to Forte/4DIAC for simulations
- Want to discuss with Greenfoot author
LMS Forte 
- Would like to be able to demo to individuals when asked specfics


March:
[Online access to student statistics for distance learning school]
   
By end of June:
LMS Forte:
- More HW FBs (need larger blocks of time)
  like Tacho motor; Sonar (I2c);
        LCD; Sound on board (if possible)
4DIAC/forte Applications formalization
- Lego Segway
- Line Follower with Timed Events instead of E_DELAY


Summer: 
NXTBee and distributed applications

Feb.11 More Project Notes

Blinky works under hg version with smaller ecos
next:- avr with led, motor and light sensor support.


next steps:
- code review
--- stable version
--- cleaned-up version
--- lab version


Blinky support functions:
- void InitLed(void);
- delay( x)


Fix (must be pushed into hg!!!!!)
Warning about Strings  need in Stringdict.h
to add include:
#include

Feb. 10 Next Step- Boot blinky in new forte

Just project notes today:
Moved into Dropbox folders.


cmake process is repeatable.


Next step move code from summer into project.
Change lmsmain.cpp so boot blinky works


What are .cdl files? eCos related

Feb.8 SAM-BA again

For SamBa 2.10 on Vista use  com port LMS connected to with usb to serial driver.

For SamBa 2.9 on XP use Atm6124 TestBoard USB driver

http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3883&category_id=&family_id=&subfamily_id=1586

Sam-Ba Users Guide (see p.7.8)

Flashes under Vista now, 
eCos is much smaller .Only flashes 9 sectors now instead of 14 or 15..

Jan.29 hg cMake set-up

Q:\Carolyn\hg4\forte\2010\forte1103WS\FORTE   last good autoconf workspace

Get forte source

•  First check-out from hg 
• http://fordiac.hg.sourceforge.net/hgweb/fordiac/forte/

Put forte source under eclipse

• create WS directory
• Import into Eclipse the hg clone directory as an existing project 
• Check copy source into eclipse project (optional)

Copy built ecos under eclipse

• create directories bin/lms and copy the ecos include and lib directories into it.
• create bin/lms/src directory

Generate Makefiles using Cmake

• Install cMake
• Open cMake Gui 

• For source directory enter the Eclipse project directory.
• For build directory, enter the top level binary directory (usually pathto/bin)
• Configure
• Press configure button
• From the dropdown for: Specify the generator for this project
• Choose: UNIX Makefiles

• For cross compiler use first 
• choose toolchain  with UNIX makefiles and press configure
• 
  
• Operation System: eCos
• Compilers for C:     arm-elf-gcc 
• and for C++:  arm-elf-g++
• Need to include path if not installed under cygwin
• path to target  
• Usually same as path to build binaries
• This has to be changed when ever workspace / file location changes
• then
• clear cache (will not clear the toolchain default)
• choose options and press configure.
• enter the text file with the options like below and press configure

INCLUDE(CMakeForceCompiler)

# this one is important
SET(CMAKE_SYSTEM_NAME eCos)

# specify the cross compiler
CMAKE_FORCE_C_COMPILER(arm-elf-gcc GNU)
CMAKE_FORCE_CXX_COMPILER(arm-elf-g++ GNU)

# where is the target environment 
SET(CMAKE_FIND_ROOT_PATH  C:/Users/Carolyn/Desktop/DistCntl/lms/forte012811WS/FORTE/bin/lms)

# search for programs in the build host directories
SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
# for libraries and headers in the target directories
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

• Chose options wanted and press configure. 
• Check LMS - (A system must be checked.)
• Check FBDK, but uncheck IP
• Check FBs needed (none in example)
• Uncheck all 3 real data types (not available in LMS)
• Press generate
• In Eclipse make all
• (Note: under cygwin in lms/bin dir - make forte also works)
• Generate forte.bin separately or as part of flashing bat file
• arm-elf-objcopy --gap-fill 0xFF -O binary forte.elf forte.bin
• Notice now .elf  before no extension
• Ready to flash and test on LMS
