ath79: modify mtd partitions for Buffalo BHR-4GRV2
This commit modifies mtd partitions define for Buffalo BHR-4GRV2 and
move it to generic subtarget.
In Buffalo BHR-4GRV2, "kernel" partition is located behined "rootfs"
partition in the stock firmware. This causes the size of the kernel
to be limited by the fixed value.
0x50000 0xe80000 0xff0000
+-------------------------------+--------------+
| rootfs | kernel |
| (14528k) | (1472k) |
+-------------------------------+--------------+
After ar71xx was updated to Kernel 4.14, the kernel size of BHR-4GRV2
exceeded the limit, and it breaks builds on official buildbot.
Since this issue was also confirmed in ath79, I modified the mtd
partitions to get rid of that limitation.
0x50000 0xff0000
+----------------------------------------------+
| firmware |
| (16000k) |
+----------------------------------------------+
However, this commit breaks compatibility with ar71xx firmware, so I
dropped "SUPPORTED_DEVICES += bhr-4grv2".
This commit requires new flash instruction instead of the old one.
Flash instruction using initramfs image:
1. Connect the computer to the LAN port of BHR-4GRV2
2. Set the IP address of the computer to 192.168.12.10
3. Rename the OpenWrt initramfs image to
"bhr4grv2-uImage-initramfs-gzip.bin" and place it into the TFTP
directory
4. Start the tftp server on the computer
5. While holding down the "ECO" button, connect power cable to
BHR-4GRV2 and turn on it
6. Flashing (orange) diag LED and release the finger from the button,
BHR-4GRV2 downloads the intiramfs image from TFTP server and boot
with it
7. On the initramfs image, create "/etc/fw_env.config" file with
following contents
/dev/mtd1 0x0 0x10000 0x10000
8. Execute following commands to add environment variables for
u-boot
fw_setenv ipaddr 192.168.12.1
fw_setenv serverip 192.168.12.10
fw_setenv ethaddr 00:aa:bb:cc:dd:ee
fw_setenv bootcmd "bootm 0x9f050000 || bootm 0x9fe80000"
9. Perform sysupgrade with squashfs-sysupgrade image
10. Wait ~150 seconds to complete flashing
And this commit includes small fix; BHR-4GRV2 has QCA9557 as a SoC,
not QCA9558.
