I had a M5475evb board ,rev b, with Motorola Dbug as the bootloader
last night, I reflashed the bootflash without storing the original one
Later, I used an old version, 3b.1a.1b instead, but did not work
There was a source copy which had the version 4a.1b.1c on freescale's web, also did the same result

Where could I find a workful Dbug boot?
Thanks!
