Debian SDK Not booting in am62p (Am62x dev kit)
Added by Rajkumar Dumala 27 days ago
Hello There,
We have a MitySOM-AM62x Development Kit and the AM62P family SoM as well. I flashed the Debian image onto the SD card and tried to boot the board, but it didn't boot, and nothing is printing on the Putty terminal (/tty/USB1 on Linux).
Could you please help me understand why this is happening?
We have previously worked with the TI evaluation board and their Debian SDK for development. Can this be directly ported into Critical Link's development kit?
The reference SD card from Critical Link seems to have a Yocto-based SDK (apt was not available). For our application requirements, we need to install the EtherCAT Igh master and ROS2 Humble (from source) on the Debian SDK. Could you provide the procedure to flash a Debian OS?
Thank you,
Rajkumar.

Hi Mike,
I was on leave for the past four days, so I wasn't able to communicate.
When we tested on the TI EVM, the behavior was slightly better, and we were able to achieve 800 Hz.
Thank you,
Rajkumar.

Hi Rajkumar,
It's not clear why there would be a difference between the two. It's the same processor / frequency design.
You might try and disable all of the peripherals you don't intend to use in the device tree you are using, as they might be consuming processor bandwidth. Some candidates (I don't know your design):
- Heartbeat LEDS
- Display(s)
- CAN bus
Maybe there are some network services that could be shut down as well.
It might also be worth experimenting with the CPU governor and forcing it to a fixed performance vs an on-demand setting (not sure what it is now, but often it defaults to on-demand).
