A brief introduction about how to use te Glyn TMPA900-CPU-Board devices with Linux and U-Boot.
We are going to replace all contents of the NAND flash - so make sure to have a backup if there is any valuable data on your device. For now we assume you have U-Boot installed on your device already.
setenv ipaddr <your IP address> setenv serverip <your TFTP server IP address>
tftp 0x40600000 uImage nand erase 0x80000 0x300000 nand write 0x40600000 0x80000 0x300000
Erasing the environment resets all U-Boot configuration setting to their defaults. This is useful if you upgraded U-Boot from an old release.
