Error : Blinky on stm32f303 discovery board.
Hi,
I'm trying to run blinky on stm32f303 discovery board.
But I get the the following error, when I try to upload the bootloader to
board.
Can someone tell me what is the reason for that?

Hi,
openocd is not able to connect to target, and there are many possible reasons for that.
Usually it’s not either finding the USB device, openocd is not compiled with the support
for the adapter, or permissions when trying to access it.
You can extract the openocd command from the BSP debug script, and try running
it with more debug output. This sometimes gives more data about the cause of the failure.
openocd -f board/stm32f3discovery.cfg -c init -d 3
If ST-Link is not supported, the output should tell you that.
Check that you OS can see the debug port:
—8<----
[marko@ubuntu:~]$ lsusb | grep ST
Bus 002 Device 009: ID 0483:3748 STMicroelectronics ST-LINK/V2
—8<——
If it does, then try running openocd as root; if this succeeds then it’s an issue with
device permissions.
Hope this helps,
