[En-Nut-Discussion] Firmware >256K flash issue

[Ulrich Prinz]

Hi Mathieu,

my code not reached this size... I wonder what you did to the radio :)
I use openocd and EIR myself and you can send me the binary for testing 
if you like.

Just for curiosity, is there anything in your code that might be 
interesting for the EIR community? Sometimes it looks like I am the only 
one who is developing for the nice piece of hardware.

Best regards, Ulrich
