Craig, I enabled ext2 support in uboot and it worked fine. At some point i used the ext2load command to load uImage from the compact flash (after using pinit), but forgot to tell the address a2000000, I suspect it assumed 0 and didn't respect the protect flags (I had just used it moments ago), because now I have a brick :-) Is this possible, would it unprotect uboot sectors or ignore the flags somehow? - Alexandre |

Hmm. I think the default load address should be a2000000 but it's possible that ext2load uses a different default. As far as unprotecting the flash, it won't do that by itself; you have to do it manually or it won't happen. Could it be that the boards separated while you were inserting/removing the CF card or something, and possibly fried the gumstix?

The boards were well tied one to another. It was sort of working, I then turned the power off (without realizing what could've happened at that time). When I turned it back on, it was printing this to the console: Resetting CPU ... resetting ... Resetting CPU ... resetting ... Resetting CPU ... resetting ... Resetting CPU ... (and that repeated continuously. Pressing keys didn't do anything) I found that strange and then wondered what was happening, but nevermind. I'll arrange to try to have it reflashed. Thanks! - Alexandre |

Pressing keys didn't do anything) Interesting -- it printed that, but not the u-boot "splash screen?" C |
