I have a developed a portable RFID scanner that can scan a MIFARE tag and send the tag ID via BLE to a connected App.
Working fine using the Adafruit Bluefruit M0 feather.
Being a battery operated unit, I have a auto power logic to power up , scan and then cut out power to the board.
The issue is this : When the user presses the scan button, the MCU powers up and there is this 3 sec dealy before the bootloader yields to the machine code. User finds this delay a nuisance. Now that the code is proven I want to erase the bootloader and do away with the start up delay.
I have the choice of Atmel Studio 7 + ICE
or the Segger Embedded Studio + JLink programmer.
Which is easy to learn and use ? And are there any other options ?
