Downloading and Flashing Images + +4.1 Reflash U-boot Image using U-boot + + =>run update_uboot + + You may want to try + =>tftp $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, + if the new u-boot doesn't boot, you can plug the board into + your PCI slot and with the supplied driver and sample app + you can reburn a working u-boot. + +4.2 Downloading and Booting Linux Kernel + + Ensure that all networking-related environment variables are set + properly (including ipaddr, serverip, gatewayip (if needed), + netmask, ethaddr, eth1addr, fdtfile, and bootfile). + + =>tftp $loadaddr uImage + =>nand write $loadaddr kernel $filesize + =>tftp $loadaddr $fdtfile + =>nand write $loadaddr 7e0000 1800 + + =>boot + +5 Notes + + The console baudrate for SIMPC8313 is 115200bps. |
