Errors after getting started

Support

Hi everyone !
i have a little issue here, i have flowed the getting started guide but when i try to run odrv0.axis0.requested_state = AXIS_STATE_CLOSED_LOOP_CONTROL
nothing happens, and when i dump the errors i get :
In [1]: dump_errors(odrv0)
system: not found
axis0
axis: Error(s):
UNKNOWN ERROR: 0x00000010
UNKNOWN ERROR: 0x00000020
motor: Error(s):
UNKNOWN ERROR: 0x00004000
sensorless_estimator: no error
encoder: no error
controller: no error
axis1
axis: Error(s):
UNKNOWN ERROR: 0x00000010
motor: Error(s):
UNKNOWN ERROR: 0x00004000
sensorless_estimator: no error
encoder: no error
controller: no error

i am only using axis0
I have the latest version of Odrivetool, and a freshly received 3.6 odrive board

This is all i typed during the getting started guide:

I think you will have to update the firmware before fixing this.

pip install --upgrade odrive
odrivetool dfu

Yep that worked !
but now i am getting these errors

In [29]: dump_errors(odrv0)
system: Error(s):
ODRIVE_ERROR_DC_BUS_OVER_REGEN_CURRENT
axis0
axis: no error
motor: Error(s):
MOTOR_ERROR_SYSTEM_LEVEL
sensorless_estimator: no error
encoder: no error
controller: no error
axis1
axis: no error
motor: Error(s):
MOTOR_ERROR_SYSTEM_LEVEL
sensorless_estimator: no error
encoder: no error
controller: no error

Update ALL GREEN YAY !!!
Turns out i forgot to put a ‘-’ before the value of odrv0.config.dc_max_negative_current
now it’s good
Thx

You may also need to enable your brake resistor if you are using one. That fixed this same error for me.
