P2041: SRIO link test in UBOOT

gouravjain · ‎02-10-2019

Hi All,

In our board based on P2041rdb, SRIO lines are connected to IDT SRIO switch.

Its in 2x mode. serdes lines SD_TX04/SD_RX04, SD_TX05/SD_RX05 are connected to IDT SRIO switch.

I want to perform link test in UBOOT and then linux.

Can some one let me know how to proceed further ??

Thanks,

Gourav

Use Ubuntu 12 or Ubuntu 14. Do not use Ubuntu 16 or Ubuntu 18.

Usually the following command sequence is used for SDK 2.0 installing under Ubuntu 14.04 64-bit:

sudo apt-get install ubuntu-minimal ubuntu-standard patch vim-common sed wget subversion git-core coreutils libbonobo2-common unzip texi2html texinfo libsdl1.2-dev docbook-utils gawk python-pysqlite2 diffstat make gcc build-essential xz-utils g++ desktop-file-utils chrpath libgl1-mesa-dev libglu1-mesa-dev autoconf automake groff libtool xterm libncurses5-dev cvs tofrodos

a) command: ls -l /bin/sh

Message: /bin/sh -> dash

b) command: sudo dpkg-reconfigure dash

Answer after password – No

Message:

Removing 'diversion of /bin/sh to /bin/sh.distrib by dash'

Adding 'diversion of /bin/sh to /bin/sh.distrib by bash'

Removing 'diversion of /usr/share/man/man1/sh.1.gz to /usr/share/man/man1/sh.distrib.1.gz by dash'

Adding 'diversion of /usr/share/man/man1/sh.1.gz to /usr/share/man/man1/sh.distrib.1.gz by bash'

c) command for checking: ls -l /bin/sh

Message: /bin/sh -> bash

mount SDK source .iso file
cd <sdk-install-dir>.
./sources/meta-freescale/scripts/host-prepare.sh

Usually Linux recommends also run the following command: sudo usr/sbin/visudo

Download and unpack the QorIQ Linux SDK v2.0-1703.bz2

Install SDK v2.0-1703

bitbake fsl-image-minimal

New version of SDK usually uses new version of Linux kernel. For example SDK 2.0 Linux kernel is Linux kernel 4.1.8.

Some problems or mistakes are fixed in new SDK version.

I'm trying to compile SDK-2 kernel, but its giving error...

While SDK-1.4 is working fine. So if you guide me how to use SRIO in SDK-1.4, will be easier for me to proceed.

Pavel · ‎03-25-2019

There is the same driver is the SDK 2.0 ("./drivers/uio/fsl_srio_uio.c").

yeah ..i understood your's point.

But, my question is why should I use SDK-2 ?? While same srio files are available in SDK-1.4

Pavel · ‎03-20-2019

Find SRIO driver in kernel source folder.

The following path is needed if T1040RDB board:

/QorIQ-SDK-V2.0-20160527-yocto/build_t1040d4rdb/tmp/work/t1040d4rdb-fsl-linux/linux-qoriq/4.1-r0/git/drivers/uio

Use similar path for the P2041.

Have a great day,

Hi Pavel,

I can see "./drivers/uio/fsl_srio_uio.c" in my working SDK-1.4.
So whats the point of going for higher version SDK-2???

Cant i use all the SRIO related features by using SDK-1.4?

gouravjain · ‎03-21-2019

Thanks for help.

I missed out to enable one more thing. Anyways i got the source code.

Now i'm going to fuse new image into the card and i'll let you know if any issue comes.

See the Sections 9.9.18 and 12.3.5 of SDK 2.0-1703 documentation:

https://www.nxp.com/docs/en/supporting-information/QORIQ-SDK-2.0-IC-REV0.pdf

These Sections contains information for installing and testing SRIO on the P2041/P3041/P4080/P5020/T4240/B4860.

Hi Pavel,

Thanks for the response.

Can you pls share the link from where i can download SDk-2.0 freely.

gouravjain · ‎02-10-2019

Currently we are using "Linux-3.8.13-rt9-QorIQ-SDK-V1.4" and there is no USDPAA SRA application.
Pls let me know how to get it.
