HadCon's and HadCon2's Software for/of Atmel

Introduction

... needed ..

ATMEL

Toolchain & Access

Prerequisites

Since USB devices are not assigned statically and may change, in the following it is assumed that the serial/usb devices used to program/access the Hadcon are:
• programming with olimex: /dev/olimex
• access: /dev/hadcon2 An automatic assignment of specified USB devices to those dev ports is described here
  at "usbdev - dynamic dev symbolic link and proper access rights"

AVR

• AVR - gcc based
  • avr : e.g. zypper se avr
  • Warning: reading http://www.nongnu.org/avr-libc/bugs.html pointing to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30289 tells us, that memset is wrong compiled
    • avr-gcc 3.3.5 - OK
    • fixed in 4.1.3, 4.2 branch, and >= 4.3.0.
    • typically you get 4.1.2
• avr-gcc, avr-libc
  • openSuse - Repository: (from: http://www.mikrocontroller.net/articles/AVR_Eclipse#openSuSE)
    1. zypper ar http://download.opensuse.org/repositories/CrossToolchain:/avr/openSUSE_13.1/ <Some Name>
    2. zypper install avr-libc cross-avr-gcc

avrdude

• AVRDUDE - AVR Downloader/UploaDEr
  • AVRDUDE is a utility to download/upload/manipulate the ROM and EEPROM contents of AVR microcontrollers using the in-system programming technique (ISP).
  • https://www.nongnu.org/avrdude/
• Programming:
  
  $> avrdude -v -P /dev/ttyUSBx -pc128 -c jtagmkI -x jtagchain=0,1,0,8 -Uflash:w:<hadcon>.elf
  • Don't forget setting fuses, to be done when HadCon2 is programmed the first time:
    $> avrdude -v -P /dev/ttyUSBx -pc128 -c jtagmkI -x jtagchain=0,1,0,8 -Uefuse:w:0xff:m -Uhfuse:w:0x19:m -Ulfuse:w:0xe0:m

  HadCon Note

  In case of HadCon(1) use jtagchain=0,1,0,4 instead

avarice

• obsolete alternative to avrdude
  • Development of avarice has been discontiuned
  • avarice: http://avarice.sourceforge.net
Show ... (Expand all... Collapse all)Hide ... (Expand all... Collapse all)
• Programming:
  
  avarice -c 0,1,0,8 --jtag /dev/ttyUSBx -B 1000000 --erase --program --file <hadcon>.elf
  • Don't forget setting fuses, to be done when HadCon2 is programmed the first time:
    avarice -c 0,1,0,8 --jtag /dev/ttyUSBx -B 1000000 -W ff19e0

  HadCon Note

  In case of HadCon(1) use jtagchain=0,1,0,4 instead

• Note:
  • avarice does not support the --program feature from version 2.12 on, so make sure you have maximal 2.11.
• Local build:
  1. Download sources :
     
     %FOREACH{"av_version" in="2.11,2.12"}%
     • avarice-$av_version (local copy)
     %NEXT{"av_version"}%
  2. Patches
     1. Download patches for g++ -version ≥ 6.4:
        
        %FOREACH{"av_version" in="2.11,2.12"}%
        • $av_version
          %FOREACH{"av_file" in="pragma.h,jtagrw.cc"}%
          • patch.avarice-$av_version.$av_file
          %NEXT{"av_file"}%
          %NEXT{"av_version"}%
     2. Apply Patches:
        
        %FOREACH{"av_version" in="2.11,2.12"}%
        • $av_version
          %FOREACH{"av_file" in="pragma.h,jtagrw.cc"}%
          • patch src/$av_file < patch.$av_version.$av_file
          %NEXT{"av_file"}%
          %NEXT{"av_version"}%
  3. build
     • • ./configure && make or
       • ./configure && make && make install
• Pitfalls & Obstacles:

  programming

  HadCon's and HadCon2's CPLD/FPGA size differs avarice must have the right arguments
  $>avarice -c 0,1,0,8 --jtag /dev/olimex -B 1000000 --erase --program --file api.elf

  Set fuses

  First time you are programming a new hadcon board with “Olimex” (s.below) you have to “set fuses” (up-to-now I don't now what this means) by issuing from your cross compiling computer the following sequence:
  $> avarice -c 0,1,0,8 --jtag /dev/olimex -B 1000000 -W ff19e0
