Reflash NAND

I have both BBB on debian now but would like to try and install Angstrom on one of them again. I have several questions for now which are:

1. Will reflashing Remove all the files on the EE memory and write only the image file in with none of the old stored files deleted completely including all the files and directories I have added erased? Where can I find information on hot to erase all the system files and reflashing to a virgin looking system ready for reflashing?

2. The last time I tried to flash angstrom I could never get past the blank screen, was there supposed to be changes I had to do to the uenv file so it would bring up the angstrom screen?

3. Is thecloud9 environment capable of running Java?


Haven’t encountered the problems you’re asking about, but I find this a good starting place to learn from:
