This is a WiFi to UART bridge, it should complete following features to make it a product:

• Connect to different port to connect different target board
• Support configuration file similar to .kermrc
• Support Wireless credential configuration.
• Connect to laptop via USB should also support.

Wireless JTAG

At the end of last year, I followed ryan instructions to make a JTAG with Raspberry Pi, after connected via telnet, I can use it with OpenOCD, it act as a host machine, this is not the way I expected, I want a real remote JTAG, I want to connect to it with OpenOCD directly, no telnet is required, I know this kind of product exists in the market, the price is not good for me, for student and for geeks.

Make Blog Public

I run this blog for two years, mainly serving as my learning note, and improve English written skill, I deeply understand the fact that, sharing is a good way to make achievements, and may correct my understanding if I was wrong (which is very likely).

Another reason is many of the posts I wrote are quite easy to understand, this may help some other entry level users.

So this year I want to make it public.
