DRA7xx Linux SDK installation issue

Jianwei Gao
Prodigy 10 points

Hello,

I am trying to install Linux SDK for TI jacinto6 Vayu EVM board. From TI website: https://www.ti.com/tool/PROCESSOR-SDK-DRA7X#tech-docs, I downloaded the DRA7xx EVM Linux SDK 64-bit Binary and Software Developers Guide for Processor SDK Linux Automotive.

According to the Software Developer Guide (ubuntu 14 or ubuntu 16 is recommended), I installed Ubuntu16.04 Linux at first. Then I run DRA7xx EVM Linux SDK binary on this Ubuntu16.04. I got some error which mentioned that the Ubuntu version is not 14. Then I installed Ubunt14.04 on this machine and followed the procedure described in Developer Guide. Then I got python mismatch issue. The reason is that some TI script downloaded ‘repo’, which version is relative new and it requires python3. However, on Ubunt14.04, the default python is python2. I installed python3, but still got errors. Then I googled this issue and found an old ‘repo’ which name is ‘repo-1”. I downloaded the ‘repo-1’ and replaced the original bin/repo installed by TI script with this ‘repo-1’. The TI Linux SDK was installed successfully.

Since I need to build a wifi driver, so I need to fetch source with command “./bin/fetch-sources.sh”. However, I always got below errors. I tried this in office and at home, so it should not be a proxy issue.

Could you please provide a procedure to properly install Linux SDK for Jacinto6 Vayu EVM and fetch all related kernel source code? Thank you very much for your support.

Thanks

    Hello Jianwei,

    Please note that the DRA7x is one of our previous generation of devices and the SDK and releases on ti.com would be in as-is condition with limited support. So we would like to know the background of working on this device family. Can you share the details?

    Regarding the connection errors, it could be possible that some of the publically posted repositories could have either moved or deprecated.  But please note that the release page has the bootfs and rootfs tar files that can be directly used on the TI EVM board for any testing.

    Thanks.

    Hi Praveen,

    We have a mutual customer who has chosen TI Jacinto 6 for their automotive product.  There are major concerns with this platform on performance with data throughput.

    My team member Jianwei needs to get this platform running using a Linux-based OS as a reference to compare against QNX OS with our throughput testing.

    Please let me know if we can get this resolved soon, or if we need to get on a conference call to discuss this issue.

    Hello Don,

    Thanks for the background.

    As previously noted, your team member need not build the Linux SDK and instead he can use the pre-build bootfs and rootfs tar files for his performance evaluation. 

    Thanks.

    Hello Praveen,

    I need to run throughput test for a wifi driver (for Synaptics PCIe wifi module). To do this, I need wifi driver's binary, iperf2, hostapd/wpa_supplicant utilities, etc.  Does the pre-built rootfs contain everything for this test?

    Thanks

    The pre-build rootfs must contain all the tools & binaries, that you can build out of the given source package.

    Thanks.
