flashing TI CC2531 stick with TI Zstack ZNP firmware

[AndrewLinden]

Just wanted to say that I successfully flashed the CC2531 USB stick with the TI provided firmware that can be found here: https://github.com/mtornblad/zstack-1.2.2a.44539/tree/master/CC2531

I used Arduino MKR1000 board which is a 3.3V board so I just connected CC_DD_I and CC_DD_O together. I used the "Write anywhere" branch from @Sjord https://github.com/wavesoft/CCLib/pull/18 And I had to remove the second line from the end (:0400000500002DD0FA) because https://github.com/wavesoft/CCLib/issues/16

However I could not flash the hex file for CC2531 from here: https://github.com/zigbeer/documents/tree/master/zigbee-shepherd I did not debug this further because I succeeded to flash CC2531ZNP-Pro-Secure_LinkKeyJoin.hex

I also had troubles trying to flash using an 8Mhz 3.3V Pro Micro. I traced the problem to that I could not communicate reliably with the Pro Micro serial at 115200 speed.
