[edit] Serial Boot Log info
From the OpenWRT wiki:
[edit] CFE memory report
Tot mem: 131072 KBytes CFE mem: 0x00F00000 - 0x00FCC810 (837648) Data: 0x00F414A8 - 0x00F418F4 (1100) BSS: 0x00F41900 - 0x00F66810 (151312) Heap: 0x00F66810 - 0x00FCA810 (409600) Stack: 0x00FCA810 - 0x00FCC810 (8192) Text: 0x00F00000 - 0x00F396D4 (235220)
[edit] MTD partitions
Creating 5 MTD partitions on "bcmsflash": 0x000000000000-0x000000040000 : "boot" 0x000000040000-0x000000240000 : "linux" 0x000000240000-0x000000ee0000 : "rootfs" 0x000000fe0000-0x000000ff0000 : "radio" 0x000000ff0000-0x000001000000 : "nvram"
This means that DD-WRT firmware must be smaller than 0xee0000-0x40000 = 14976 KB (14.625 MB).
- Do not flash builds after 33986 nor before 35452. They are too big and can overwrite the 'radio' partition!
[edit] Revert to OEM Firmware
WARNING: There is no webrevert file, and the other method to flash the C8 back to OEM has had mixed results.
- Some have reported reverting to stock here and here using a specific file name and IP addresses: procedure.
[edit] Reset
Do not 30-30-30 reset ARM devices!
- Use the GUI, or hold the Wi-Fi button to reset the C8.
- If the GUI cannot be accessed after setting a password, try enabling https via telnet.
[edit] Installation
Tested: TP-Link Archer C8 V1 with TP-Link firmware: Archer C8_V1_150515
- Download DD-WRT firmware: factory-to-ddwrt.bin
- "Reset to factory defaults" via the OEM Archer GUI.
- Also from the Archer GUI, upload the factory-to-ddwrt.bin file.
- Wait at least one minute
- Access DD-WRT GUI at 192.168.1.1, set password, then GUI reset (Admin->Factory Defaults) again
- v2 should use the same process, and the 'v1' file.
- 33006 has also been tested.
- v3 is an EU model. There is one report of a v3 running DD-WRT, but with no details.
- No reports of a v4 (also EU). Warning: v4 has different flash size from v1-3.
More information and alternate download locations: FAQ: Where do I download firmware?
[edit] Recovery Mode
The v3 and v4 CFE has a built-in Webpage Firmware Recovery mode for bricked routers: see TP-Link article.
It may be possible to retrofit a v3 CFE onto v1/v2 models, but this is untested.
