The smoked TRB (Serial No. 5) is in repair. After removing the DC/DC converters (48V, 2,5V, 3.0V) there is no short-circuit anymore and the ETRAX is working again. The replacement FPGA were delivered today (2005-07-11) and will be soldered tomorrow.

Removed pads (due to unsoldering):

pinn	function
AB22	GND
AA22	x
AB21	x
AB16	x
AB04	x
Y1	x
V1	x
A2	x

After resoldering the FPGA, the ETRAX-chip is not working anymore. This is the second Axis-Chip, which is defective after soldering in the vapor-phase reflow-oven.

New AXIS-ETRAX-chip was soldered "by hand". The processor is working and network connection is established, but I can not load the FLASH. Strange!
