Add Support for Archer C50 (W) v6 BR

For Developers
1

Could you add support for this router Archer C50 (W) V6 BR? It is exactly the same router as the TP-Link Archer C50 v6 (CA/EU/RU), but the partition layout is different. I compiled an image myself and it's working.

If anyone is interested, you can get my code here: https://github.com/FabianoTSS/openwrt — it's on the openwrt-24.10 branch.

I am trying to build an image factory, I am getting the following log below.
The error occurs when trying to install the firmware by the web. I have already fixed the TPLINK_HWID, but now it's giving an MD5 error. I have no clue how to solve it.

[ rsl_sys_verifyFirmware ] 3780:  Image md5 checksum is not correct, len is 5c0338!

My image codes is:

define Device/tplink_archer-c50-w-v6
  $(Device/tplink-v2)
  IMAGE_SIZE := 7808k
  DEVICE_MODEL := Archer C50 (W)
  DEVICE_VARIANT := v6 (BR)
  TPLINK_FLASHLAYOUT := 8MSUmtk
  TPLINK_HWID := 0x600500c
  TPLINK_HWREVADD := 0x6
  DEVICE_PACKAGES := kmod-mt7615e kmod-mt7663-firmware-ap
  IMAGES := sysupgrade.bin
endef
TARGET_DEVICES += tplink_archer-c50-w-v6

The header of the original firmware looks like this:

The Header of the openwrt image looks like:

I solved this problem it was because I needed a factory image and I was using a sysupgrade image. But now the problem changed:
