- JC 08:52 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P Software Development: RE: Toolchain Versions Question
- We are working on the SDK 09 release right now. This is built using yocto kirkstone and uses gnu 11.3 and bumps u-boot to 2023.01 and the kernel to 6.1. The release is supposed to be imminent though unrelated problems keep redirecting r...
- What is the recommended approach to toolchain management?
For example, I see the toolchain today uses CXX compiler GNU 9.2.1.
* Is it recommended to "stay in that lane" to maintain support?
What if I want GNU 11?
* Is that a ... - NW 08:06 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P Software Development: RE: Error with certificates in the Docker container

- JC 07:14 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P Software Development: RE: Error with certificates in the Docker container
- I pushed an updated Dockerfile which deletes the git executables from the SDK since the system git is newer and uses the correct ca-certs.

- The issue is the certs in the SDK toolchain are old. I'm not even sure why yocto ships its own certs but it does... If I force it to use the system's git under /usr/bin then the clone works fine. I'll see if I can update the Dockerfil...

I am attempting to use the mitysom_ubuntu:22.04 image created via containers/am62xx/make.
We have a cmake project that wants to fetch some stuff at configure time.
The fetches are failing with... - JC 03:10 PM MitySOM-AM57X Software Development: RE: AM57x QT Starter Guide 2022 problem
- According to TI they only tested this release on Ubuntu 18.04. I've tested it on 20.04 and it works, but it doesn't work on 22.04+. I've updated the wiki to remove the reference to 22.04

- For additional information, I tried both in virtual machine and dual boot setup symptoms are same.
- I am just trying to follow QT Starter Guide 2022 step by step.
First I guess, there is no package called qt5-default in Ubuntu 22.04, So I installed qtbase5-dev, qtchooser,qt5-qmake, qtbase5-dev-tools by hand.
Additionally, standart ...

I don't know, I've never used an SFP in a design before. - SS 04:03 PM MitySOM-AM57X PCB Development: RE: Ethernet Connectivity issues with DP83822
- Hi,
Thank you for your prompt support.
Is there any modifications to be done in the kernel side for the fiber optic communication using SFP modules ?

- Hi,
The problem is solved now. We removed the 165 ohm resistance connected in the TDP,TDM, RDP and RDM lines. Now the ethernet connectivity is okay and ping also working.
Now we are facing another problem. We are planned for RJ45...

Did you also comment out or change the original MCASP2_AXR4 line. Just to make sure that pinmux isn't getting set twice.

I will verify the voltage levels on each lines.

If the phy link goes up and down, we can ignore the processor side of things. The phy itself handles establishing a link. ... - SS 04:36 PM MitySOM-AM57X PCB Development: RE: Ethernet Connectivity issues with DP83822
- Q: Do the link lights on the ethernet jack also go on and off?
Yes. Left side led of RJ45 is go on and off. When we connect to PC, the ethernet link is showing not connected.

- Hi,
We designed our own custom AM5728 board with two DP83822 PHYs. Desired phy address are phy0 and phy 1.
In the schematic shown , we removed R219 to make it to PHY 1. The other DP83822 has COL pin pull down with 2.2k resistance is... - JC 08:48 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: DSP FPGA EMIF GPIO Failure
- Alright, let's simplify. The base module's register 0 contains some version info. You can read it 4 times in a row and then it will start repeating. For example on my board:

Okay, so that should mean your fpga code is fine. Note its a good idea to make sure the fpga_gpio.ko kernel module isn't loaded if you are trying to control it from the DSP. They could fight each ot...
