Anyone got the details on how the default memory map on Verdex XL6P and space available for rootfs work out? Thanks, Marc Marc Humphreys LogicLink Design, Inc. Office: 978-274-5673 Fax: 978-274-5674 Cell: 978-844-0196 |

Hi Marc, > Anyone got the details on how the default memory map on Verdex XL6P and > space available for rootfs work out? Pages 28-2 and 28-3 of the PXA270 Developer's Manual has a pretty decent memory map. <http://pubs.gumstix.com/documents/PXA%20Documentation/PXA270/PXA270%20Processor%20Developer's%20Manual%20%5b280000-002%5d.pdf> Note that this is the physical memory map. Once linux starts running, everything is virtual, and some stuff moves around. In terms of flash, the first 256K is u-boot, and the last Meg is the kernel. rootfs gets what's left, which is 0x01EC0000 = 32,243,712 bytes. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

Thanks Dave, Exactly what I needed - the u-boot and kernel sizes and locations. Marc -----Original Message----- From: gum...@li...
