Programming / Flashing a Blank Pluto Board

I have tried to replicate your terminal output in both Vivado 2017.4 and 2018.2 and in both situations I get stuck at the targets command

"xsct% connect
attempting to launch hw_server

as well as:

On my smart lynq, I have all the jtag connections made except for the "SRSTn". Vref, GND, TDI, TDO, TCK and TMS are all connected. And I am able to at least program the bitstream.

I'm using -

Xilinx Platform USB Cable II in conjunction with the ADALM-JTAGUART adapter.

I also installed the Xilinx cable drivers.

The platform cable 1 seems to be considerable cheaper than the platform cable 2, do you suppose the platform cable 1 should work?

Hello, I was able to figure out my issues. I can now use the run.tcl file to program the bitstream, source the ps7_init tcl and download uboot.elf

After the disconnect 64 command, the ready LED turns off and the LED1 LED turns on bright and solid. 

After doing this step, what is the next step in order to fully program the pluto board?

Can some one provide any clarification on this? 

I am just looking for some general/high level steps / procedures for flashing and programming the Pluto board. 

From what I understand, there is the bitstream, then the ps7_init tcl, then the u boot. This all needs to be put into flash, so that the fpga can be loaded upon power on. 

What is the process for loading linux/ libiio?

Sorry for the delay - many people are still out for the holidays, and will be back on Monday.

Once you have bootstrapped uboot via JTAG. You should see it's command line interface on the uart console.

The next step would be to DFU (boot.dfu) your initial uboot.

$ sudo dfu-util -D boot.dfu -a boot.dfu

But be aware in case you are still in JTAG boot mode, SPI access to NOR flash will fail until you remove the bootmode jumper.

Once you have your initial u-boot in flash, please continue using DFU to load kernel and userspace 

$ sudo dfu-util -D pluto.dfu -a firmware.dfu

Thank you for the reply, 

For clarity, I will re-list my steps and provide the output of those steps. 

1. Power on Pluto with JTAG_BOOT pin grounded, after power on, remove ground. 

2. Run JTAG Bootstrap TCL

  - Programs bitstream

  - Runs ps7_init and ps7_post_config

  - Downloads u-boot

3. At this point when the TCL is finished running from Vivado SDK, I can see the following output from the Pluto Uart

U-Boot PlutoSDR v0.20-PlutoSDR-00051-gf5f001e (Oct 15 2018 - 20:38:02 +0200)

If I try this again, but interrupt the autoboot,

I am presented with a Pluto Terminal

Can you verify that I am following these steps correctly?

In addition, when trying to use the first command provided,

$ sudo dfu-util -D boot.dfu -a boot.dfu

I get the following output on the terminal. I am using Admin cmd on windows with dfu-util installed.

No DFU capable USB device available

I can also see in my device manager that there is a new USB device labeled "USB Download gadget" and under properties of this device, it says that it is a Pluto SDR DFU

Try:

dfu-util.exe -d 0456:b673,0456:b674 -D C:\Users\KevinE\Desktop\dfu-util\dfu-util-0.9-win64\boot.dfu -a boot.dfu

If this doesn't work try to use the dfu-util deployed with the windows driver.
