Hello,
Is it possible to flash the DA14680 via USB (directly, not via a debug chip or so) ? I see the bootloader checks predefined serial lines, eg. UART ,UTX => P1_3, URX => P2_3
and so it is possibile to flash the cpu. (similar like the Production Line tool).
However, I dont see the same for USB . Is any software to do this ?
Thank you,
Device:

I dont quite get the question, there are two ways to erase or program the flash of the 68x family, either via JTAG or via UART, there is no implementation for downloading code into the flash using the USB.
What do you mean flash the CPU ? What is the feature that you ve seen on the PLT ? The PLT uses only UART in order to communicate with the DUTs attached and not USB protocol.

Hello MT,
I mean 'downloading code into the flash using the USB.' as you say, but that's not supported I see.
The board design here has the MCU with USB enabled (and its USB connector). It is small 22x22mm and
would really be nice to be able to programm/download the code/flash to MCU via USB instead the
JTAG connector or another (serial) one since that would occupy space on the board (in such small world).
Otherways said, would be nice the PLT to be able to download the code to the device via USB also (alongside the serial support in the DUT)
but I suppose that would require the MCU bootloader to be upgraded to support USB also.
We put a JTAG (with serial lines pins URX/UTX included), much like in the Sensor IoT app so it can be snapped out of the board after mass
production/programming using PLT but better if we can avoid this.
Thank you,

Hi tecktronic,
Sorry, but as i ve mentioned, there are only two ways to download code into the 68x family either via JTAG or UART, USB is not an option, at least at the moment.
