QUICKDEV2 NOTES

20100808

AVR ISP

• quickdev standart cable that has isp as serial
• connect avr dragon isp to isp header at combo cable
• avr dragon isp
  • vcc has to be connected
  • vcc: red
  • gnd: black
  • sck: yellow
  • mosi: green
  • rst: black
• works on os x

AVR JTAG

• connects to the xilinx jtag cable
• AVR ISP has to be disconnected
• jtag header
  • vcc: red
  • gnd: black
  • tdi: yellow
  • tdo: green
  • tms: white
  • sck: red
• last test on linux and osx with avarice (2.09,2.10) didn't work, starting up a gdb yields and 'cant access memory' error

CPLD JTAG

• runs under linx in vmware
• preload usbdriver
• export LD_PRELOAD=/home/david/Devel/arch/fpga/tools/usb-driver
• check usb vendor id, has to be 03fd:0008
• otherwise fxload the firmware by hand
• start impact, it should find the cable automatically, if not reboot
• the cpld gets dedecteted by it self, if not run boundairy scan
• run 'program' from context menu

QUICKDEV DEBUG HEADER

• then head pins located at the reset button
• connect to saleae LA:
  • gnd: grey
  • debug0: black
  • debug1: brown
  • debug2: red
  • debug3: orange
  • debug4: yellow
  • debug5: green
  • debug6: blue
  • debug7: violet

POC MASSSTORAGE

• makefile include 'programm' for avrdude with dragon_isp
• uart uses the quickdev combo cabel and runs at 115200
• compile works on os x
• serial screen works on os x
• masstorage device should pop in finder

POC SREG

• makefile include 'programm' for avrdude with dragon_isp
• uart uses the quickdev combo cabel and runs at 115200
• compile works on os x
• serial screen works on os x
• to debug the sreg or the fsm reduce the speed of the avr
  • program fuse divide clock by 8 internally
  • set uart baud speed to 9600 by setting UBRR1=25
  • change speed in screen session
