Question: How to flush RBL nRF51822 and BLENano? #14

Closed bojh closed 8 years ago

bojh commented 8 years ago

The arduino-nRF5 project can flush the nRF52-DK with it's buildin JLink debugger. Do I have to connect a external JLink to the RBL nRF51822 board by soldering a header to SWD-B? Or is the idea to support a serial programmer later on - especilly for BLENano?

Nope, that board has a built-in CMSIS-DAP programmer on the USB port, just select it as the programmer from Tools -> Programmer to flash the soft device etc.

Or is the idea to support a serial programmer later on - especilly for BLENano?

No plans for serial programmer, this would require use of a boot loader on the device.

The USB programmer board that comes with the Nano (MK20 based), is also a CMSIS-DAP programmer, so the above applies to it as well.

@sandeepmistry Ah OK Thanks at all for that help - I have got a better view now. I have done that, but I'm still struggling against it - a simple "blink" or "Serial" example does not work - and I think the setting and initialization is all done well.
