I will try to make it simple
I have a vesc hw 4.12 that I can connect and works perfectly under vesc tool 0.83 FW3.30
But impossible to go under the new 0.87,
it remains in limited mode. At the connection it appears the message that the firmware is too old it goes into limited mode,
I go on the firmware tab, I download to the vesc, the cursor goes to 100%,
and the following message appears in red at the bottom right: "Status serial port error: a peripheral device attached to the system does not work properly"
I tried another USB cable and another pc but nothing changes. ..
Can you help me?
