And this is my log of failure, when trying to flash the Atmega Erasing and programming require separate commands. This allows programming multiple devices of the same family at the same time. Note that unlike Atmel’s BatchISP program, dfu-programmer will only perform a single operation at a time. Unless you override it, commands which write to the microcontroller will perform a validation step that rereads the data which was written, compares it to the expected result, and reports any errors. By default, the first device that matches the id codes for the given target is selected.

The target may be qualified with the USB bus and address number of the device you wish to program. 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 at90jsb dfu bootloader anymore.
This allows using a single. By default, the first device that matches the id codes for the given target is selected.
DFU made me jump around

Another thing to do is looking up the Halfkey bootloader on the teensy. This board is way out of my Arduino comfort zone Flash blank from 0x0 to 0x17F. This is required before the bootloader will perform other commands. All of these commands support the “global options”. This block of flash is out of the normal range of flash blocks and is designed to contain configuration parameters. The offset at90uab assumed to be given in hex if it starts with a “0x” prefix, octal if it begins with a “0”, otherwise is it assumed to be decimal.
Then invoke this program to issue one or more DFU commands. This allows programming multiple devices of the same family at the same time. 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. Expected message length ofgot – 9. This option is particularly useful for the AVR32 chips trampoline code.
Checking memory from dtu to 0x17F AVR command specific below validate: Erasing and programming require separate commands. To activate the bootloader you have to have pulled down the HWE pin when releasing the RST pin, a state that my board is constantly set to, since I’ve copied the teensy design not knowing “better”.
Flash region from 0x0 to 0x17F is blank. To remove any write or read protection from any chips, a full chip erasure is required. Many targets share the same id codes.
The input file or stdin must use the “ihex” file format convention ag90usb a memory image. When the security fuse is set, almost nothing will work without first executing the erase command.
The microcontrollers come up in that mode as shipped by Atmel; or they may reenter that mode after a special hardware reset. Error writing memory data.
