Hi, I noticed you had a live demonstration on how to use the Mediatek WiFi on mangOH Red, unfortunately I noticed this too late. Hopefully some information came up that someone could use to help me. I am trying to get WiFi working on my Red (WP8548). Trying to follow the wiki: > **[mangOH Red mt7697](https://github.com/mangOH/mangOH/wiki/mangOH-Red-mt7697)** > > Primary mangOH git repository. Contribute to mangOH/mangOH development by creating an account on GitHub. and building the git repo with the SDK gives me: > Build CM4 Firmware…Done > ============================================================== > ./build.sh linkit7697\_hdk MT7697\_WiFi\_BT\_fw bl > Start Build: Mon Feb 19 15:59:15 EET 2018 > BOOTLOADER BUILD : PASS > End Build: Mon Feb 19 15:59:41 EET 2018 > TOTAL BUILD: FAIL I do not know why it says `TOTAL BUILD: FAIL`, cannot find any failed parts of the build. When trying to use MT76x7 flash tool it does not go past “Waiting for COM” when pressing `Start`. Tested, and verified the serialport used is correct. The flashtool gives me the following errors on the CLI: > libpng warning: iCCP: known incorrect sRGB profile > libpng warning: iCCP: known incorrect sRGB profile ---

Update: There was an issue with Linux (Mint 18.3) that was causing issue with the flash tool. Got the chip flashed on Windows 7. But the only thing I am seeing on console USB output is (not sure if this is normal): > loader enable 30s timeout > loader init > fota: TMP is empty, skip upgrade > jump to (0x10079000) Should WiFi now work with wifiService application for example, because I cannot get it working. Thanks again in advance! ---

It should print more than that in the console. Above it says “TOTAL BUILD: FAIL”. Did you resolve the build failure? Look at `out/linkit7697_hdk/MT7697_WiFi_BT_fw/log/err.log` ---

Hi @dfrey, Ah of course. I tried looking through the error log to see if there was something I recognized, something is definitely wrong but I cannot pinpoint what. The errorlog is attached here: [err.log](https://mangoh.discourse.group/uploads/short-url/ze5oKofvgJXXuFRwB0XcJFlFuS9.log) (8.7 KB) Maybe you have seen similar errors before? ---

Hallo, I followed the steps motioned here [https://github.com/mangOH/mangOH/wiki/mangOH-Red-mt7697-WiFi](https://github.com/mangOH/mangOH/wiki/mangOH-Red-mt7697-WiFi). But I was not able to build the project. I get ============================================================== ./build.sh linkit7697\_hdk MT7697\_WiFi\_BT\_fw bl Start Build: Di 24.

Are you building against the LinkIT 4.3.0 SDK? Note that 4.3.0 is _not_ the latest version. ---

Hi dfrey, thanks for your info. It was my mistake. I used the LinkIT version 4.6.1 instead of 3.4.0. Now the build works well.
