Trenz Electronic FPGA Modules / Linaro on TE0720
« Last post by nturner on February 16, 2019, 03:08:12 AM »
I am trying to compile the Linux Linaro image and run it on a TE0720+TE0701. One of the steps is to generate the u-boot image, as described here. The problem is that I'm not certain which platform to make the u-boot image for. I would guess "Zynq cse_qspi", or is there a TE0720 platform file somewhere?

Hi,

I acquired a second TEI0003 unit today and programming the new unit works fine so far (but then it initially worked fine with the first board as well). I don't think I was at all rough with the first board. I was pretty careful with the ESD.


re your questions: 

win10 native quartus prime lite 18.1.  I tried different USB ports.
Had problem on programming (as described)and on autodetect.

when I attempted to autodetect the jtag chain it said it was "unable to scan device chain" and offered to open jtag chain debugger.  When I click the Test jtag chain button in the debugger it reports:"Error: JTAG chain problem detected Error:No Device detected".  I don't know the jtag debugger so going deeper into it would require some reading. I tried my best guess for how to do something (some sign of life) since at this stage the warning about damaging the device is a bit moot but when I attempted to run a test, the debugger froze and eventually crashed.   I don't know if that has anything to do with the fundamental problem or it is just my using the  debugger improperly.

regards, Dana

Hi,

I don't know this tutorial, so I can't tell you if something is missing on it.  Sorry.
It's also not clear with which Vivado/Petalinux version this tutorial was created. Depending on the Vivado/Petalinux version some steps can be changed.

Try out our reference design (currently 18.2), and if you has problem, let me know.

Hi John,
Thank you for the quick reply, so I followed this tutorial here ( https://www.digikey.com/eewiki/display/Motley/Getting+Started+with+the+ZynqBerry#GettingStartedwiththeZynqBerry-Linux )  to create the image with petalinux, and the result was a directory containing the kernel, device tree and the rootfs.

There are additional configurations needed?
Ill try the prebuilt image now and let you know the outcome.
Regards,
Ailton Lopes

Hi,
did you reduced JTAG speed on time?

So from your text, I think your use Windows, correct? Which version? Native or VM?

When did this messages appears? When you open JTAG Chain with Quartus or when you try to program?
From other forum entries "209040 Can't access JTAG chain" this appears when you try to programming, correct?

Which USB Port did you use on your PC? USB1 m USB2 or USB3? You should use USB2 or USB3. Can you try out another USB Port?

Maybe you has some power problem, because modules is supplied over USB. And when you start programming, it needs more power for short time.

Can you get access with JTAG chain debugger?

Hi,
can you try out one time the prebuilt boot.bin and image.ub, please.

If I understand you correctly, you did not use  image.ub container with all included. You has separated device tree, kernel, rootfs, correct? Did you configure petalinux(and uboot) for this setup?

On Monday I received it and used the demo to test it.  It failed when I attempted to load my own design on Wednesday.  I'm not aware of any significant changes to the computer in that time. It immediately failed with a "209040 Can't access JTAG chain" error message.   From searching on this error message, this error seems to be often associated with physical issues with the jtag connection. I then wesnt back and attempted to replicate the steps I did to program the demo on Monday and received the same error.  I checked the troubleshooter and ran the diagnostic.  I found no problems and the diagnostic program found no problems. 

When I deliberately disconnected the USB and attempted to program the unit a different error message "209037 JTAG Server can't access selected programming hardware" was displayed.  I take this to mean that the original problem is somewhere downstream from the USB cord.

Hi,
did you installed some other drivers during this time? Or OS Updates?
Did you try to change something on the FTDI of the module?
Can you try out another USB connector on your PC and maybe other USB Cable?

Which OS did you use?
For WinOS there is a trouble shoot guide and a diagnose tool available:
Can you try out  this please?

For Linux are only general notes available:

Trenz Electronic FPGA Modules / Linux TE0726-2 not booting
« Last post by andersenbond on February 14, 2019, 10:59:28 AM »
Hi,
So I'm new with the TE0726-2 board and I'm having some issues running Linux on the board. I've tried both Petaliux 2017.4 and 2018.2 and got the same result that the kernel never starts. Everytime I tried the last output I get is the "Starting Kernel" from U-boot and nothing happens after that.

Basically I created the .hdf file with the script provided by Trenz in the Test_board example, used it as input in petalinux and after getting the image and everything I created the BOOT.bin and burned it in the flash memory copy the .dtb and the kernel to the SD but the kernel never gets to print anything. Id appreciate if you guys have any suggestion in how to fix this problem.

Kind regards,
Ailton Lopes

Removing
#Interface number zero is a JTAG.
# SUBSYSTEM=="usb",\
# ATTRS{idVendor}=="0403",\
# ATTRS{idProduct}=="6010",\
# ATTR{interface}=="Arrow USB Blaster",\
# ATTR{bInterfaceNumber}=="00"
# RUN="/bin/sh -c 'echo $kernel > /sys/bus/usb/drivers/ftdi_sio/unbind'"
rrom the rules file allows /dev/ttyUSBx and JTAG to work at the same time.  Created a simple loop back on the serial pins using the CYC1000 and was able to echo data back up to 3Mbps using minicom  Also, adding some pins to route the serial out to the header and validated pins were toggling using a log analyzer.
