Programming SD card for Zed

MP
Miller, Peter
Wed, Sep 25, 2019 2:21 PM

Installed using the instructions at https://www.opencpi.org/services

  •    sudo yum install yum-utils epel-release

  •    sudo yum-config-manager --add-repo=http://opencpi.github.io/repo/opencpi.repo

  •    sudo yum install 'opencpi*'

To prepare the Zed SD card, instructions in https://opencpi.github.io/OpenCPI_Installation.pdf Page 23 say:
" ...OpenCPI source tree, its path is: projects/core/rcc/platforms/xilinx13_4"
which is not there. Instead I find the desired content at:
"/opt/opencpi/cdk/zed/sdcard-xilinx13_4"

The specified procedure to copy to SD in a CentOS7 VM fails:
$ sudo cp -r /opt/opencpi/cdk/zed/sdcard-xilinx13_4/* /media/sf_SD_card
cp: cannot create symbolic link '/media/sf_SD_card/opencpi/xilinx13_4/bin/ntpd': Read-only file system
cp: cannot create symbolic link '/media/sf_SD_card/opencpi/xilinx13_4/lib/libgmp.so': Read-only file system
cp: cannot create symbolic link '/media/sf_SD_card/opencpi/xilinx13_4/lib/libgmp.so.10': Read-only file system
cp: cannot create symbolic link '/media/sf_SD_card/opencpi/xilinx13_4/lib/libgmpxx.so': Read-only file system
cp: cannot create symbolic link '/media/sf_SD_card/opencpi/xilinx13_4/lib/libgmpxx.so.4': Read-only file system
cp: cannot create symbolic link '/media/sf_SD_card/opencpi/xilinx13_4/lib/liblzma.so': Read-only file system
cp: cannot create symbolic link '/media/sf_SD_card/opencpi/xilinx13_4/lib/liblzma.so.5': Read-only file system
Resulting SD card won't boot the Zedboard.

Q1. Is the Installation Guide just out of date regarding the location of the content to copy to the SD card?
Q2. Any suggestions for the VM symbolic link copy issue?
Q3. Better to install from source as in "OpenCPI_Installation" rather than from RPMs?

Sincerely,

This is a source-install vs. rpm-install issue, and the docs should be
clearer about this distinction.  This is in fact a current work item.

If looks like the /media was mounted read-only?

Both RPM and source installations should allow you to do this.

Not sure what the "VM symbolic link issue" is.  Other email?

Do you confirm that copying from /opt/opencpi/cdk/zed/sdcard-xilinx13_4/* is correct?
Media is write-able - this issue with sym links is a VM problem and I wondered if you had a simple workaround. I'll either chase it down or go to a native linux machine to copy it.

I have certainly had problems with symlinks when mounting a "host" file
system into a VM.  I solve it by always using NFS, even between a VM and
its host.
I'm not sure that is your issue...

Yes, that is the intention of that directory.

I'm actually doing something similar later today to test some new FPGA
loading code...

Peter,

If believe  "cp -rL" is what you're looking for, for the symlink issue. The -L option: "always follow symbolic links in SOURCE". The platform specific getting starting guides tell you to use cp -rL when copying the opencpi directory within the sdcard directory.  For example the ZedBoard Getting Starting Guide says for xilinx13_3 run:
cp -rL /opt/opencpi/cdk/zed/sdcard-xilinx13_3/opencpi run/media/<user>/<partition>/

Regards,

Jerry

I have certainly had problems with symlinks when mounting a "host" file
system into a VM.  I solve it by always using NFS, even between a VM and
its host.
I'm not sure that is your issue...

Yes, that is the intention of that directory.

I'm actually doing something similar later today to test some new FPGA
loading code...

Media is write-able - this issue with sym links is a VM problem and I wondered if you had a simple workaround. I'll either chase it down or go to a native linux machine to copy it.

This is a source-install vs. rpm-install issue, and the docs should be clearer about this distinction.  This is in fact a current work item.

If looks like the /media was mounted read-only?

Both RPM and source installations should allow you to do this.

Not sure what the "VM symbolic link issue" is.  Other email?

Jim,
Still trying to get OpenCPI 1.5 from RPM, and Zedboard up. I find that the embedded OS and boot files (boot.bin  devicetree.dtb  opencpi  uImage  uramdisk.image.gz) from /opt/opencpi/cdk/zed/sdcard-xilinx13_3 can be copied to SD card and the zedboard boots PetaLinux v2013.10. But using the files from /opt/opencpi/cdk/zed/sdcard-xilinx13_4 the zedboard will not boot.

WORKS:
% sudo cp /opt/opencpi/cdk/zed/sdcard-xilinx13_3/* /media/sf_SD_card

FAILS:
% sudo cp /opt/opencpi/cdk/zed/sdcard-xilinx13_4/* /media/sf_SD_card

Also, per Jerry Darko's comment, the instructions in "OpenCPI_Installation.pdf" Section 4.1 should be revised to something like:
% sudo -RLp cp /opt/opencpi/cdk/zed/sdcard-xilinx13_4/* /media/xyz

Jim,
Still trying to get OpenCPI 1.5 from RPM, and Zedboard up. I find that the embedded OS and boot files (boot.bin  devicetree.dtb  opencpi  uImage  uramdisk.image.gz) from /opt/opencpi/cdk/zed/sdcard-xilinx13_3 can be copied to SD card and the zedboard boots PetaLinux v2013.10. But using the files from /opt/opencpi/cdk/zed/sdcard-xilinx13_4 the zedboard will not boot.

WORKS:
% sudo cp /opt/opencpi/cdk/zed/sdcard-xilinx13_3/* /media/sf_SD_card

FAILS:
% sudo cp /opt/opencpi/cdk/zed/sdcard-xilinx13_4/* /media/sf_SD_card

Also, per Jerry Darko's comment, the instructions in "OpenCPI_Installation.pdf" Section 4.1 should be revised to something like:
% sudo -RLp cp /opt/opencpi/cdk/zed/sdcard-xilinx13_4/* /media/xyz

I have certainly had problems with symlinks when mounting a "host" file system into a VM.  I solve it by always using NFS, even between a VM and its host.
I'm not sure that is your issue...

Yes, that is the intention of that directory.

I'm actually doing something similar later today to test some new FPGA loading code...

Media is write-able - this issue with sym links is a VM problem and I wondered if you had a simple workaround. I'll either chase it down or go to a native linux machine to copy it.

This is a source-install vs. rpm-install issue, and the docs should be clearer about this distinction.  This is in fact a current work item.

If looks like the /media was mounted read-only?

Both RPM and source installations should allow you to do this.

Not sure what the "VM symbolic link issue" is.  Other email?

To prepare the Zed SD card, instructions in https://opencpi.github.io/OpenCPI_Installation.pdf Page 23 say:
" ...OpenCPI source tree, its path is: projects/core/rcc/platforms/xilinx13_4"

Q1. Is the Installation Guide just out of date regarding the location of the content to copy to the SD card?
Q2. Any suggestions for the VM symbolic link copy issue?
Q3. Better to install from source as in "OpenCPI_Installation" rather than from RPMs?

Can you describe the failure?  I think I understand, but we're doing
more testing.

The sdcard image directories only have symlinks that should remain
symlinks, so in fact using cp -L is masking some other problem.

I only copied the embedded OS and boot files (boot.bin  devicetree.dtb  opencpi  uImage  uramdisk.image.gz) - no opencpi/* so no sym links. I think one or more of those files is corrupt. The procedure was:

  1. $ sudo cp /opt/opencpi/cdk/zed/sdcard-xilinx13_3/* /media/sf_SD_card
  2. Put the SD card in the zedboard and power up
  3. Open a putty terminal and log in. Success
  4. Put the SD card back into PC/VM/CentOS
  5. $ sudo cp /opt/opencpi/cdk/zed/sdcard-xilinx13_4/* /media/sf_SD_card
  6. Put the SD card in the zedboard and power up
  7. Open a putty terminal and log in. Fails

I am now installing OpenCPI 1.5 in a fresh CentOS 7.5 VM from source. I will run the scripts and build the boot images.

I have certainly had problems with symlinks when mounting a "host" file system into a VM.  I solve it by always using NFS, even between a VM and its host.
I'm not sure that is your issue...

Yes, that is the intention of that directory.

I'm actually doing something similar later today to test some new FPGA loading code...

Media is write-able - this issue with sym links is a VM problem and I wondered if you had a simple workaround. I'll either chase it down or go to a native linux machine to copy it.

This is a source-install vs. rpm-install issue, and the docs should be clearer about this distinction.  This is in fact a current work item.

If looks like the /media was mounted read-only?

Both RPM and source installations should allow you to do this.

Not sure what the "VM symbolic link issue" is.  Other email?

Hi Peter,

I have just (re)built the xilinx13_4 from source, make the SD card and
successfully executed on it.
This is based on a development branch rather than 1.5, but I don't know
of anything that changed here.

After building the source tree for xilinx13_4 (and the driver), I had to
do (in the source tree):

make deploy Platform=xilinx13_4
make deploy Platform=zed:xilinx13_4

The first line was unexpected and actually also builds RPMs as a side
effect, and we'll clean it up a bit in 1.6.
The result was an SD card in cdk/zed/zed-deploy/sdcard-xilinx13_4
And I used:
cp -R -p cdk/zed/zed-deploy/sdcard-xilinx13_4/* /Volumes/BOOT

(Where /Volumes/Boot was the mount point of the SD card).

I was doing this since we have just done a xilinx19_1_aarch32 version
for zed and I wanted to back-test.

I have certainly had problems with symlinks when mounting a "host" file system into a VM.  I solve it by always using NFS, even between a VM and its host.
I'm not sure that is your issue...

Yes, that is the intention of that directory.

I'm actually doing something similar later today to test some new FPGA loading code...

Do you confirm that copying from /opt/opencpi/cdk/zed/sdcard-xilinx13_4/* is correct?
Media is write-able - this issue with sym links is a VM problem and I wondered if you had a simple workaround. I'll either chase it down or go to a native linux machine to copy it.

This is a source-install vs. rpm-install issue, and the docs should be clearer about this distinction.  This is in fact a current work item.

If looks like the /media was mounted read-only?

Both RPM and source installations should allow you to do this.

Not sure what the "VM symbolic link issue" is.  Other email?

  •    sudo yum install 'opencpi*'

To prepare the Zed SD card, instructions in https://opencpi.github.io/OpenCPI_Installation.pdf Page 23 say:
" ...OpenCPI source tree, its path is: projects/core/rcc/platforms/xilinx13_4"
which is not there. Instead I find the desired content at:
"/opt/opencpi/cdk/zed/sdcard-xilinx13_4"

The specified procedure to copy to SD in a CentOS7 VM fails:
$ sudo cp -r /opt/opencpi/cdk/zed/sdcard-xilinx13_4/*

Q1. Is the Installation Guide just out of date regarding the location of the content to copy to the SD card?
Q2. Any suggestions for the VM symbolic link copy issue?
Q3. Better to install from source as in "OpenCPI_Installation" rather than from RPMs?

Hi Peter, I have just (re)built the xilinx13_4 from source, make the SD card and successfully executed on it. This is based on a development branch rather than 1.5, but I don't know of anything that changed here. After building the source tree for xilinx13_4 (and the driver), I had to do (in the source tree): make deploy Platform=xilinx13_4 make deploy Platform=zed:xilinx13_4 The first line was unexpected and actually *also* builds RPMs as a side effect, and we'll clean it up a bit in 1.6. The result was an SD card in cdk/zed/zed-deploy/sdcard-xilinx13_4 And I used: cp -R -p cdk/zed/zed-deploy/sdcard-xilinx13_4/* /Volumes/BOOT (Where /Volumes/Boot was the mount point of the SD card). I was doing this since we have just done a xilinx19_1_aarch32 version for zed and I wanted to back-test.
