2018-01-07: Created the configuration. At present it does not work; I
believe because of tool-related issues. I do the following:
a) Open TeraTerm, select COM7 at 1200 baud, type a few ENTERs, and
close teraterm.
b) Execute the following command which claims to have successfully
written to FLASH.
/bossac.exe --info --debug --port COM7 --usb-port=0 --erase --write --verify -b nuttx.bin -R
But the code does not boot. There is no indication of life.
c) Repeat a) then
bossac.exe --info --debug --port COM7 --usb-port=0 --verify -b nuttx.bin
And it says that the content of the FLASH is not good.
