How to flash a new nRF51822 with mbed firmware?
Hi, I've been working with the Redbearlab BLE Nano for prototyping and now am moving to a PCB and still want to use mbed. I designed and soldered up a PCB with an nRF51822 based on the reference design. I (possibly naively) tried flashing the new board from the MK20 dongle connecting the Vdd, GND, SWCLK, SDIO pins with no success. I received the 'fail' text file with 'sw error' when I drag the hex (BLE_initial_test_RBLAB_BLENANO.hex) to the dongle (in Windows).
What's the usual process for flashing the mbed firmware onto a new board? Do I need to use additional pins? Do I need to buy a programmer?
I'm fairly new to the ARM/mbed platform so apologies if my question is way off base or has gaping issues. I've spent hours googling and haven't found examples for this step of development.
