Hi,
Recently, John Hansen's Enhanced Firmware version 1.28 was posted to BrixCC. I'm
trying to find out if the Source Code is available for that version.
The source package http://bricxcc.sourceforge.net/lms_arm_nbcnxc_src.zip appears
to be for the old firmware (1.06) only (as of Sept 16 2009).
It's difficult to tell when a new version of the Firmware is posted to BrixCC
since the filename does not get updated.
In addition, is there any detailed Changelog describing the differences between
the 1.0x and 1.28 firmware versions?
TIA

There is an update to the NXTGCC toolchain. I have added a complete download
package including arm-elf-gcc, Elipse, and a converter (from IAR to gcc). Check
it out at http://nxtgcc.sf.net
Best,
Rasmus

This is only for debugging purpose!

Fortunately the processor has a special boot mode to recover from that without
ressorting to JTAG. But I appreciate the concept of "un-bricking a bricked NXT
brick" ;o)

The download page has this nice little notice:
DISCLAIMER: You have to open the LEGO® MINDSTORMS® NXT and solder on PCB. Please
note that the LEGO Group warranty of the NXT is invalid after doing this.
Neither IAR Systems nor the LEGO Group will take any responsibility of damages
done to your NXT once it has been opened. We strongly recommend previous
knowledge of soldering on PCB and open electronics.
Is this required or intended for in circuit debugging?
I can see how it could un-brick after a bad firmware load.

If you haven't heard yet, IAR has released a free LEGO MINDSTORMS version of
their compiler. It happens to be the same compiler that LEGO uses to build the
NXT firmware so it makes it extraordinarily simple to build your own modified
firmware images. I don't think it is available for non-Windows platforms. This
is the tool I have been using to develop the enhanced NBC/NXC firmware for the
NXT.
