First of all the flat device tree handling depends on CONFIG_SYS_BOOTMAPSZ. So I have to define a valid value. As far as I understand the initial memory map for Linux there have to be space for the kernel (text+data), fdt_blob and kernel parameters (at least). I'm unsure with an embedded init ramdisk as produced by simpleImage. The simpleImage can quickly grow up over 6MB with embedded initrd. So I borrowed this configuration (8MB) from most other configurations (mainly PowerPC). br, Stephan > > > + > > + > > BTW: One black line is enough > > Thanks, > Michal -- Viele Grüße, Stephan Linz ______________________________________________________________________________ OpenDCC: http://www.li-pro.net/opendcc.phtml PC/M: http://www.li-pro.net/pcm.phtml CDK4AVR: http://cdk4avr.sourceforge.net/ CDK4NIOS: http://cdk4nios.sourceforge.net/ CDK4MSP: http://cdk4msp.sourceforge.net/ CPM4L: http://download.opensuse.org/repositories/home:/rexut:/CPM4L _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
