Hello. thank you for your time. I am using a translator so apologies if some of the words are wrong.
I have some questions:
-Is there a W861 development board available for purchase?
-what does the error "fail! Error code: "NAK" mean when flashing firmware?
-Is it really possible to get wifi working on the W806 by using the W801 SDK? are there any real-world examples of this?
-can I dump existing firmware from a device to a .fls file - to save a firmware from device to a file?
thank you
1.There is currently no W861 development board available.
2.The reason for NAK prompt is that in most cases, due to unstable serial port connections, some USB to serial port boards do not support high baud rates. If this error persists, you can try reducing the download baud rate.
3.The W806 chip does not have Wi-Fi function.
4.Unable to read firmware file from device.
1- thank you
2- hmm OK. I am trying to flash a binary built using W801 SDK. I am flashing at 115200 baud. I can flash other binaries OK at this speed and faster. what other reasons are there for NAK error?
3- OK. Maybe I am mis-reading this post - http://ask.winnermicro.com/article/186.html - where it says "actual testing by netizens shows that W806 is still equipped with Wi-Fi and Bluetooth cores)" - this sounds like wifi should work on W801?
4- that's a shame. could this feature be added to the Upgrade Tools app for dumping via UART?
thank you.
2-If there are no errors when downloading other firmware, it may be that there is a problem with the firmware you compiled yourself. Besides adding application layer code, have you modified configuration parameters or compiled firmware that is large?
3-There is no dispute about the fact that W806 does not have WiFi functionality.
4-Very sorry, we are unable to provide such a feature through the Upgrade Tools app or other tools.

Item 4 is not shame :)
This is a requirement for security and protection of copyrighted firmware from unauthorized copying and reverse engineering. Simple practice
