To get console access via UART on Akai devices you have to proceed like on the pictures below :
On my AKF i have 6 pins, sometimes on MPC there is less pins. Use an USB/TTL converter to avoid damage on your board. You can use this one as on the photo : USB-TTL Converter
Connect like this :
- GND from Akf to GND on usb stick (you can measure gnd when running with a voltmeter), if you have 0v between measuring point and the gnd, there is a big change that the measuring point is a gnd.
- Rx from Akf to Tx on usb stick
- Tx from Akf to Rx on usb stick
/!\ Do not connect Pins 5v or 3.3v
Connect USB dongle to your computer. Connect USB type B on force to the same computer ( if you dont do this, you can have inconsistent messages when sending commands or receiving messages in the console application).
Then when its done, download putty and run it. In session choose Serial and adjust Com1 port to the port used by your USB/TTL converter. On my side its often COM6, COM4 or COM7. Change speed on 115200, and click Open. I wrong port has been chosen you will have an error message. Otherwise you'll have black screen.
Then power on your force and Uboot prompt & start will appear.
Let linux boot then you will see login prompt (force login:), waiting for you to login.
If you have already a firwmare with ssh enabled, you can log like this on your device. Otherwise if you dont have the login, you'll have to go into uboot console.
To do this and just after booting your device, there is a quick message allowing you to interrupt boot process.
