Command Line interface

Command line interface

The CL is available via the UART (front panel or eventually Zynq). As of 7/11 the available commands are listed below.

The I2C controllers that can be currently addressed are

1. I2C 1 (for power supplies)
2. I2C 2 (for clock synthesizer)
3. I2C 3 (for FF devices on the VU7P)
4. I2C 4 (for FF devices on the KU15P)
5. I2C 6 (for the two FPGAs)

Nota Bene

• the ADC command output for the last four outputs (ADCIN 16-19) are weird. This affects the 3.3V, the V_MGTY2_VCCAUX, V_MGTY2_AVCC and V_MGTY2_AVTT voltages. Please ignore these values.
• to use the command line interface to manipulate the I2C 1 device you must first stop the monitoring task which reads the PMBUS status registers. This can be done via task MON suspend and restarted via task MON resume. The way this is implemented it just freezes the FreeRTOS task, so there might be some residual errors when you restart the task.

The output of the help command is listed below.
