Dragino LSN50 and STLink
|
Hello everyone, I noticed the Dragino LSN50 board has been ported to Zephyr and that's pretty cool. I have one of this board and following the page https://docs.zephyrproject.org/latest/boards/arm/dragino_lsn50/doc/index.html#flashing-an-application-to-dragino-lsn50 they say 'Connect the Dragino LSN50 to a STLinkV2...'. Since the the board has no dedicated connect to JTAG/SWD, I read the stm32l072cz datasheet and found out the the SWDIO is PA13 and SWCLK is PA14. I connected these pins at my J-Link Ultra in the following way: JTAG -> LSN50 pin 6 -> pin GND pin 7 -> pin PA13 (SWDIO) pin 9 -> pin PA14 pin 19 -> pin VDD (+3.3V) And tried to connect the Ozone but it did not work. At Ozone, in J-Link Settings I have the target device: STM32L072CZ, Target Interface: SWD:auto speed and Host Interface: USB. If someone knows how to connect the LSN50 board and could explain me I'll be very grateful. All the best,

Hi Gustavo, Sorry, I'm not familiar with Dragino, nor J-Link, maybe Endre would know better, as he did the board port. Erwan
