Title: Programming Arduino Bootloader takes 10+ Minutes
Post by: jamesC4S on March 16, 2013, 02:03:11 am
Programming an arduino bootloader on an ATmega328 is taking on the order of 10-15 minutes to complete.

Here's the command I'm using:
avrdude -patmega328p -c buspirate -P /dev/tty.usbserial-A6005lHR -e -Ulock:w:0x3F:m -Uefuse:w:0x05:m -Uhfuse:w:0xDA:m -Ulfuse:w:0xFF:m -U flash:w:optiboot_atmega328.hex

Here's the initial output:

Code: [Select]
Detecting BusPirate...
**  
**  Bus Pirate v3b
**  Firmware v5.10 (r559)  Bootloader v4.4
**  DEVID:0x0447 REVID:0x3043 (24FJ64GA002 B5)
**  http://dangerousprototypes.com
**
BusPirate: using BINARY mode
avrdude: AVR device initialized and ready to accept instructions

Any ideas why it is taking so long?  Have I missed something?
