I have done some experiments with u-boot (version 1.2.0) and with linux kernel (version 2.6.23) and it seems to be that the limitation of 8MB is not anymore the problem. I have built u-boot and linux for ppc405 (virtex-4). I have set the CFG_BOOTMAPSZ to 16 MB: #define CFG_BOOTMAPSZ (8 << 21) /* 16 MB */
and Linux has picked up the command line parameters which were set in u-boot. >/* > * For booting Linux, the board info and command line data > * have to be in the first 8 MB of memory, since this is > * the maximum mapped by the Linux kernel during initialization. > */ > #define CFG_BOOTMAPSZ (8 << 20) /* Initial Memory map for > Linux */ -- View this message in context: http://www.nabble.com/U-boot-and-linux-command-line-parameters-tp23698384p23712750.html Sent from the linuxppc-dev mailing list archive at Nabble.com. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
