CLI mode provide wide set of commands to manipulate module.
To enter CLI mode, switch COM port "Baudrate" to "123456".
In this mode firmware read user input and process commands. Commands is case sensitive and should be lower-case. "Backspace" can be used for command line correction. "Enter" with empty command line cause re-execution of previous command.

The "flash status" command read and print SPI Flash "Status register 1" and "Status register 2" values. Please refer your Flash datasheet to registers bit layout.

...
| To get full control on SPI bus firmware disable FPGA power supply before this operation. After each flash command, use "power on" command and "fpga reset" command to run FPGA. |
Example:
> flash status
SR1 00 SR2 00
...
The "flash id" command read and print first 3 bytes from result of SPI Flash "READ IDENTIFICATION" command.

The "flash erase" command execute SPI Flash "Bulk Erase" command. Processing of this command usually require some time. User should wait command to complete before power off module or enter next command. Refer your Flash chip datasheet for maximum required time.
