Linux/TMDSEVM572X: Developing for 572XEVM/AM5718 - What Gotchas will we Encounter with RedHat vs. Ubuntu?

Hi,

I'm relatively new to developing Linux on TI SOC platforms. I'm working with a TI572X EVM.

**I need to know, if I install Red Hat LInux on one of my corporate PC's instead of Ubuntu version 16.04, what potential gotchas could we face? I believe our IT department will allow me to install Red Hat natively on a PC, and the hope there is that we would have more control over what protocols (e.g. TFTP, NFS) are allowed.**

Recently, we ran up against stumbling blocks with network booting the Sitara 572x EVM with Ubuntu 16.04 running within VirtualBox on a Windows 7 host machine, apparently due to policies put in place by our IT department. For instance, when the Sitara is attempting to mount the development FS on an Ubuntu/Virtualbox, Wireshark shows the response from the NFS server is administratively prohibited. I've tried all kinds of gyrations with the firewall and opening the ports, but no luck thus far. But the operation just works on my personal Windows machine at home running Ubuntu within VBOX.

Please let me know what you think...

Thanks!

Hello,

Please check this guide:
processors.wiki.ti.com/.../Processor_SDK_Linux_Getting_Started_Guide
Configure a Linux Host chapter. There you could find what are the recommendations.

Hi,

Yes I know the Linux SDK calls out Ubuntu 16.04 for the SDK. That would be my preference. But due to my corporate IT department's constraints, I MAY only be able to install Red Had natively on a PC and put it on our corporate network. Alternatively I can install Ubuntu 16.04 natively on a machine, but I imagine it will be a real pain if I cannot place that machine on the internet when it comes to downloading packages.

So, I'm still very much interested in where we'll run into issues with the latest Red Hat distro. I'm not sure if this will be mainly an issue with compatibility, for instance, with the Linaro tool chain or whether there are other dependencies. I will research this as best as possible, but I would greatly appreciate it if TI could help point me in the right direction.

Thanks!

Jeff

Hello,

Let me try to check with someone more aware.

Thank you!!

I'm "almost" able to network boot with the 572xEVM using the BBB as an intermediate TFTP and NFS server. This maybe a work-around for the apparent communication issues in the NFS mount between the EVM (NFS client) and my laptop with Ubuntu/VBOX (NFS server).

Hello,

Answer:
"It should be possible PSDK to be install on RedHat host machine. Some setup scripts should be modify and the host check to be skip."

Hope this helps.
