I have a mc7455 connected to a mikrotik board which doesn’t support usb 3.0 and therefor I use the at!usbspeed=0 command to set it as usb 2.0 only.
If I don’t do this it won’t be recognized by the router.
I tried moving to Verizon FW on the device that didn’t support this command and had to tapeout the pins in order to upgrade the FW but then I had to reapply the command to enable usb2.
My question is, if I had done a FOTA upgrade to the old Verizon FW instead of moving to it would it keep the usb2 setting?
Just to clarify the order of actions I want to do:
- Have a device running latest generic and usb2 mode set by at command
- Preform FOTA upgrade of old Verizon FW(upgrade to same version as generic) , causing a switch to Verizon FW and restart
- Now would I get the device running latest Verizon FW and usb2?
