- Openblocks A6
- Intro
- =====
- This default configuration will allow you to start experimenting with the
- buildroot environment for the Openblocks A6. With the current configuration
- it will bring-up the board, and allow access through the serial console.
- How to build it
- ===============
- Configure Buildroot:
- $ make openblocks_a6_defconfig
- Compile everything:
- $ make
- Updating board over TFTP
- ========================
- Copy the content of output/images to the root of your TFTP server.
- Connect serial and ethernet, power up board and stop it in U-Boot:
- DRAM (DDR2) CAS Latency = 5 tRP = 5 tRAS = 14 tRCD=5
- DRAM CS[0] base 0x00000000 size 512MB
- DRAM Total size 512MB 16bit width
- Addresses 8M - 0M are saved for the U-Boot usage.
- Mem malloc Initialization (8M - 7M): Done
- NAND:64 MB
- POST: mac verify Eth0 PASSED
- CPU : Marvell Feroceon (Rev 1)
- Streaming disabled
- Write allocate disabled
- USB 0: host mode
- Net: egiga0
- Hit any key to stop autoboot: 0
- openblocks>>
- Load kernel from tftp:
- setenv serverip <tftp-server-ip>
- setenv bootfile uImage.kirkwood-openblocks_a6
- bootp && tftp
- Write it to nand:
- nand erase 0x590000 0x1c5c000
- nand write.e $loadaddr 0x590000 0x1c5c000
- Load rootfs from tftp:
- setenv serverip <tftp-server-ip>
- setenv bootfile rootfs.jffs2
- bootp && tftp
- Write it to nand:
- nand erase 0x2214000 0x1dc4000
- nand write.jffs2 $loadaddr 0x2214000 0x1dc4000
- Configure kernel to use rootfs:
- setenv root /dev/mtdblock5 rootfstype=jffs2
- saveenv
- boot
