Here is the datasheet for the bootloader: Note that unlike Atmel’s BatchISP program, dfu-programmer will only perform a single operation at a time. When the security fuse is set, at90ub nothing will work without first executing the erase command. They seem to be important.

I tried and tried and couldn’t figure out what I’m doing wrong until I’ve read someone writing in a forum that in a case of a flashed program there wouldn’t be the generic ag90usb bootloader anymore. And this is my log of failure, when trying to flash the Atmega Checking memory from 0x0 to 0x17F Yes, delete it Cancel.

Global Options –quiet – minimizes the output –debug level – enables verbose output at the specified level Configure Registers The standard bootloader for based chips at90ubs writing data bytes which are not relevant for the AVR based chips.

The following link [ http: The target may be qualified with the USB bus and address number of the device you wish to program.

Flash region from 0x0 to 0x17F is blank. To use it, first connect the device to be programmed and ensure that it comes up in DFU mode. I was trying to get this code running http: This option is particularly useful for the AVR32 chips trampoline code. Another thing to do is looking up the Halfkey bootloader on the teensy. All of these commands support the “global options”. The only way to clear the security fuse once set is to use a JTAG chip erase, which will also erase the bootloader.

There must be an even number of hex digits, but the sequence can be any length. By default, the first device that matches the id codes for the given target is selected. The microcontrollers come up in that mode as shipped by Atmel; or they may reenter that mode after a special hardware reset.

Luckily Atmel gives you the DFU hex files on the download page. AVR command specific below validate: About Us Contact Hackaday. Many targets share the same id codes. This is required before the bootloader will perform other commands.

The offset is assumed to be given in hex if it starts with a at90ub prefix, octal if it begins with a “0”, otherwise is it assumed to be decimal.

This block of flash is out of the normal range of flash blocks and is designed to contain configuration parameters. Then invoke this program to issue one or more DFU commands.
