Compilation - - Assuming you're using BASH (or similar) as your shell: - - export CROSS_COMPILE=your-cross-compiler-prefix- - make distclean - make MPC8313ERDB_XXX_config - (where XXX is: - 33 - 33 MHz oscillator, boot from NOR flash - 66 - 66 MHz oscillator, boot from NOR flash - NAND_33 - 33 MHz oscillator, boot from NAND flash - NAND_66 - 66 MHz oscillator, boot from NAND flash) - make - -5. Downloading and Flashing Images - -5.1 Reflash U-boot Image using U-boot - - NOR flash: - - =>run tftpflash - - You may want to try - =>tftpboot $loadaddr $uboot - first, to make sure that the TFTP load will succeed before it - goes ahead and wipes out your current firmware. And of course, - have an alternate means of programming the flash available - if the new u-boot doesn't boot. - - NAND flash: - - =>tftpboot $loadaddr <filename> - =>nand erase 0 0x80000 - =>nand write $loadaddr 0 0x80000 - - ...where 0x80000 is the filesize rounded up to - the next 0x20000 increment. - -5.2 Downloading and Booting Linux Kernel - - Ensure that all networking-related environment variables are set - properly (including ipaddr, serverip, gatewayip (if needed), - netmask, ethaddr, eth1addr, rootpath (if using NFS root), - fdtfile, and bootfile). - - Then, do one of the following, depending on whether you - want an NFS root or a ramdisk root: - - =>run nfsboot - or - =>run ramboot - -6 Notes - - The console baudrate for MPC8313ERDB is 115200bps. |
