prototype not working
I powered up my first 100LX based board, and unfortunately it did not
I have these major parts on the board:
ETRAX100LX, 8MB SDRAM, 4MD FLASH, BCM5221A4KPT.
I am trying to download the image using flashitall, but the program just

few minutes, link may get dropped and I had to reset the board to bring it
I have printed the schematic in pdf format and uploaded it to our website.
it is available at www.vitalsystem.com/Network.pdf
I hope somebody can figure out what's wrong with this design. I will be very
grateful. I am already running late on the delivery schedule and hope I can
complete this project in due time.
