He now works for Red Hat in the desktop group, and also manages a company selling open source calibration equipment.

It’s a community-based project which helps to repair anything. At the end of programming, the new application will start running on the EVK This allows programming multiple devices of the same family at the same time. If you xvr32 on native Linux, you can run the shell script that performs all the steps for you.

You can already program this kind of hardware in Linux, using clunky commands like: 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.

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


Once the new user application firmware is programmed in the on-chip Flash memory in the range [h-end of the Flash array]the USB MSC bootloader updates the Avf32 user page configuration word to avoid restart at next start-up and resets the part. To use it, first connect the device to be programmed and ensure that it comes up in DFU mode. Erasing and programming require separate commands.

You will normally need to start by issuing the “erase” command; the default security policies prevent extracting firmware, to prevent reverse engineering of what is usually proprietary code.

How do I do that? This trampoline code ensures that the application code starts at h and is located above this address. The only way to clear the security fuse once set is to use a JTAG chip erase, which will also erase the bootloader.
