We only have data for the 6254-TX-DAE-RI, which should be worse than the model you have.

Please supply the MTBF data for the 6252-TX-X8D-RI.
Thank you and best regards,

- Thanks Nathan. I have noticed that on the SDK 10 builds. TI recently removed the matrix-gui recipe so we just need to remove our bbappend.

- TI maintains a separate -rt kernel branch, that has the realtime kernel patches applied. I should be able to apply the same patches to our kernel commits to create a comparable -rt branch that supports our SOM.

- Will we get this for free in SDK 10? I think it is kernel 6.6. I thought RT went mainline completely in 6.12? I am probably wrong.

- Hi Iseori,
I double-checked your schematic's phy and magnetics parts, and nothing looked wrong.
Note that the magnetics symbols J7/J8 are not correct. However, I looked up the "lpjg16414aenl":https://www.l-p.com/file/datasheet/lpjg1...

- Hi, Jonathan
Thank you for your prompt response.
We should be able to resolve this issue, currently at “Kernel: 5.10.168-01697-g501ba3235e01-dirty”.
Can you please check if there is a workaround in the 5.10 kernel?
Thank you a...

- Hi Iseori,
We have released an errata relating to emmc boot detection. See here: https://support.criticallink.com/redmine/projects/mitysom_am62x/wiki/Errata_and_Module_Product_Change_Notifications.
Fixes for this have been released... - Occurs on certain products, boots normally when product cools down.

- Hi Iseori,
I tested a 10Mbps link using our devkit and the KSZ9131RNXI PHY and had no issues. The PHY linked and I was able to send network traffic without issue. We have not used the DP83867IR phy in any design.

100/1000Mbps work well.
But, 10Mbps is only LINK and ping does not work. (both fixed 10M and auto-negotiation)

- Hello,
How is the USB0 device configured? As a gadget device (rndis, cdc, serial port, mass storage device, etc.)?
We have not seen this behavior here, I'd like to try to reproduce your setup if possible.
With regards,
Mike
- USB0 is set to device mode.
It stops working on some laptops.
The driver is detected but communication stops.
The problem does not occur when connecting through a USB hub.
Have you ever seen a similar case?

In Ti Arago documentation it implied we needed to add ARAGO_RT_ENABLE=1 to our image bake but ... - JC 09:26 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P Software Development: RE: Recommended quick method to install Linux image on EMMC storage for high volume products

- Thank you, Jonathan. We were able to adapt the mitysom-auto-flash-emmc image and use it in our layer to flash the emmc. It only takes about 90 seconds after boot to flash it.
