Qspi Boot Issues; Mct Issues - Enclustra Mars ZX2 User Manual

(b) Open Device Manager
(c) Universal Serial Bus controllers
enable Load VCP checkbox
(d) Reboot the computer if the COM port is still not detected
3. Reinstall the FTDI drivers if the problem persists
If the computer does not output any character in the terminal program:
1. Check that the FTDI device is set to UART mode:
(a) Download and open FT_Prog utility (this is a third party tool offered by the FTDI company
to configure FTDI devices)
(b) DEVICES
(c) Check that for Port A and B the RS232 UART property is true
2. Check that the baud rate for the UART in the block design matches the baud rate set in the
terminal program
3. If the UART used is mapped to the EMIO pins in the PS, resetting the ARM core will not suffice.
Reprogramming the PL is necessary, as the UART lines go through PL.
4. Make sure that Enclustra MCT software is not open. After closing it, unplug and plug in again
the USB cable corresponding to the UART communication.

QSPI Boot Issues

If the Mars ZX2 SoC module is not able to boot from the QSPI flash:
1. Use Vivado to program the flash
(a) Make sure that the Memory Device part type is correctly selected
(b) Make sure Erase and Program options are enabled
(c) Select Entire Configuration Memory Device for Address Range
2. If the problem persists, a possible solution is to first erase the flash, and then program it either
from Vivado or Vitis
Please refer to Section 4.1.2 for details on QSPI flash programming.
5.6

MCT Issues

If the Mars ZX2 SoC module is not enumerated in the MCT:
1. Detach all USB cables and power
2. Close all other tools that may be connected to the FTDI device (Vivado Hardware Manager,
Vitis, UART terminal).
(a) Force close the hw_server process if it is not closed by Vivado/Vitis after closing the hard-
ware server.
3. Configure the boot mode according to section 3.2 and try again.
Boot from QSPI fails after programming:
1. Detach all USB cables and power
2. Configure the hardware to boot from the QSPI flash according to section 4.1.2.
3. Reattach USB cable an power accordingly and try again.
