Why does this go to error handler?

[Mr4]

Hi! I have a code that is supposed to develop CAN-bus communication, but these two functions go straight to error handler. Any suggestions why that might be?

for reference I'm using the nucle-l433rc-p board.

Hello,

Reproduced the issue.

R19 (100ohm) needs to be soldered too to connect MCO output from ST-Link to the HSE OSC_IN of your MCU.

From what do you deduct that SB68/70 aren't bridged? I claim to say that they do look to have a gap in between. Also do you want me to choose which of them i want to clear the bridging or both of them?

That's not what he said.

He said they are bridged - by zero-ohm "resistors":

SB64 isn't bridged in your picture, but SB68 / SB70 are, with a zero ohm.

which is what I see in the picture:

He said you need to remove those zero-ohm links, and fix SB64 so that it is bridged:

You'd need to bridge SB64, and clear the bridging on SB68/SB70, so that the 8 MHz from the ST-LINK is passed.

Did you manage to get it working? or not yet?

Did you solder R19?
