Another bootloader @ 3.3v & internal 8MHz clock w/SD card...

ok..

well I updated the title.. :slight_smile:

since I have the base +3.3v/8MHz internal clock Arduino going.....

I'll focus now on the two remaining issues at hand for this board:

1.) cant upload any sketches using IDE 1.0+.... I dont believe this is a board 'problem'.. just an IDE 1.0+ problem.. that needs some fixing, however I am not 'clear' on the fixes I read..

Confused on the correct directories I need to be working with..

I have a 'hardware' folder in my MAIN Arduino directory..

  • Arduino_1.0 >>
    *** hardware >>
    ***** arduino
    ***** breadboard
    ***** tools

and then I 'also' have a folder called 'hardware' in my sketches folder (that in My Documents >> Arduino)

  • seems I need to add either an Arduino.h or a pins_arduino.h file to one of these directories?
  • I need to edit my boards.txt file (the one located in the Arduino_1.0 >>> hardware >>> breadboard/boards.txt folder Im assuming?..not in My Documents >>> hardware >> breadboard/boards.txt

2.) (and this is probably the most important currently) the SD card is NOT working. :frowning:

I have is set up as so:

SD PIN >>> Arduino
DAT2(9) >>> NOT USED
CD/CS (1) >>> D10
CMD/DI(2) >>> D11
VSS1/GND(3) >>> GND rail
VDD/V++(4) >>> +3.3v rail
CLK/SCK(5) >>> D13
VSS2/GND(6) >>> GND rail
DAT0/DO(7) >>> D12
DAT1(8) >>> NOT USED

I have a cap on VSS1 and VDD (+3.3v) pins.

this is an SD card 'adapter'... that I stick my micro SD cards in.. (I have soldered right angle headers on it, to fit in the breadboard.. this has worked before.. with lever shifters/voltage dividers, and Arduinos running @ 16MHz and +5v)

  • I have tried many micro SD cards (at least 5)
  • I have tried 3 different SD card adapter all with right angle headers that have worked in other non-minimal applications..

you think the software/libs need to be edited to work @ with a 8MHz board?

I was hoping/under the impression that using a bootloader that s native +3.3v & 8MHz internal clock would mean direct/easy interface with microSD? :frowning:

any ideas?

thanks!!

update:

SdInfo sketch gives this as my error message:

SdFat version: 20110902

type any character to start

card.init failed
SD errorCode: 0X1
SD errorData: 0X0

basically all sketches fail to init the card.. so Im 'missing' something.. :slight_smile:

All voltages check out on the meter too.. (rails check out at +3.3v... pins on chip are +3.3v...... pin on SD card is +3.3v...etc)

thanks for any suggestions on chasing this down! :slight_smile:
