Hi, Just downloaded the latest 24th Oct Beaglebaord ROM and installed it on my SDCard and booted up the Beagleboard and now I get an error message “Disc Drive not Known”. I can clear the error and boot continues but I’ve noticed that my RAM drive is missing. If I look at task display I see: Dynamic Area – RAM Map [Drive 4] and System Memory Allocation – Ram Disc 655536K. If I zero the Ram Disc memory to 0K and then drag it back up then the error message comes back. If I go in to Configure and Discs then disable teh RAM disc option then I again get the error message. Should not the RAM Map show Drive 0 as reverting back to the previous ROM Image and booting does show the RAM Map against Drive 0. Has something being built incorrectly in or is this as a result of some recent change that is not yet complete? |

Chances are that Sprow has accidentally broken RAM discs with some of his code tidying he’s been doing recently. I’ll take a look into it, unless Sprow gets there first… |

Ah – it looks like I left in one of my experiments in researching the density=0 bug, and RAMFS is registering with FileCore with 1 fixed disc (and hence drive 4) rather than 1 floppy disc. Easily resolved. Also as a mental note to myself RMLOADing test versions of RAMFS only works for the first test, because it gets killed and restarted (hence reverting to the ROM copy) when the disc is resized: I think that’s why I concluded it worked on earlier testing. |

I had similar issues when testing some changes to RAMFS. In fact, it turned out my changes were impossible to softload because of the way half of the RAM disc behaviour is actually implemented in the Kernel (i.e. all of the dynamic area part). Annoying! PS: there are new ROMs on the ROOL site which have Sprow’s latest fix in now. |
