##Hi.
I make a demo GPS device with Sara SFF , and AFF (N211 rev2) and I have some problem.
I want use this battery type with 3.6 V cell voltage for my project, but when I connect the battery + to te 3.3 Volt and to the below GND the module send 1.4-1.6 volt to my server and the GPS won’t work well. [When I connect the battery to the left side Battery + GND nothing is happening]
I want to debuging this devide at runtime. I want see the variable values and more in real time [I use VS2019 and Visual Micro] but I am willing use sany other free software for debuging.
For answere 4.: The variable value prints via serial is not enought. I want make a normal debugging accross JTAG or SWD with GDB. Remember i have AFF (not just SFF) for developing. I want to buy a hardware debugger but i don’t know wich is working fine and won’t really expensive. Maybe the next one?:
We will change the dev. devices to 412 so the hardware debugger must work on all sara AFF , SFF devices.
For answere 1.: Remove the soldering jumper need only for usb + unchargable battery using same time? Only for useing unchargeble battery dont need remove the jumper? (on unchargable battery test, my device wont work correctly )
If the Serial output isn’t enough a SWD debugger is required. In the office we use an Atmel ICE.
Other SWD Programmer also may work.
It isn’t required to remove the zero-ohm resistor, just for safety. It disables the recharge capability.
In the office we often use the 3.6v saft batteries, we really like them. But we usually use two of the 14500 to be able to provide the max pulse for the sara module.
Hi Jan.
Thanks for your answares!
Could you help me with what solredable or pluggable adapter they use to connect the atmel-ice to the Sara board?
I want to use same solution with your company.
