- MW 12:12 PM MitySOM-AM57X PCB Development: RE: I/O voltage levels
- The SOM ties the following AM57x voltage IO domains to 1.8V. You will need to use level shifters on your board to get to +3.3V IO interfaces.

- Hello Mike,
Thank you for your swift and helpful response.
We are planning to use I2C3, I2C4, and I2C5 interfaces of AM57XX in our design.
Kindly correct us if we are mistaken — as we understand from the documentatio... - MW 11:41 AM MitySOM-AM57X PCB Development: RE: I/O voltage levels
- Hello,
You should use level shifters to shift up to 3.3V. Do not pull the I2C pins directly to 3.3V or modify the SOM.
Our Dev Kit schematic uses TCA9803DGKR, but there are several shifters avialable that should work.
Which I... - In the data sheet of MITY-SOM_AM57F SOM board page 4, it is mentioned that the AM57XX MFIOs are operating at 1.8V level except mmc1 pins. We have an I2C connections that goes to AM57XX processor, we need the voltage levels of the I2C pin...

The U-Boot build is working fine. I haven't tried the SD card image you mentioned yet, but I will try it and update you.
Thank you.

I was just looking into this error case last week. Do you happen to be using a sandisk sdcard?

Hope you're doing well.
We received the AM62A SoM today from Critical Link and inserted it into the AM62x Development Kit.
We flashed the SD card with the reference microSD card image (tisdk-default-image-mitysom-am62ax.roo...

Update on the above comment:
It is working now. The issue was that pins B23 and F20 were already being used in the main_gpio_p3_pins_default node for the P3 connector. I commented out those two pins, and now UART5 has started ... - RD 11:54 AM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P Software Development: RE: Debian SDK Not booting in am62p (Am62x dev kit)
- We’ve now implemented the changes you suggested, and the OS is working fine.
Since we only copied the U-Boot and device tree from the Critical Link (CL) build into the TI file system, we needed to explicitly enable main_uart5 in the d...

- Nothing beyond some of the MIPI camera streaming.
Do you have a specific encoding in mind? A gstreamer pipeline we could try? - Have you done any performance testing with video encoding? We are specifically looking for the power consumption delta between AM62A HW encode vs AM62 software encoding.

Ok. I rebuilt the image using TI's SDK 10.01 debian trixie am62pxx-evm build (vs. the am62xx build) and only copied the boot files (in the first partition) and added our device tree.

The image I provided was for a MitySOM-AM62x, not an MitySOM-AM62P. You'll need to redo what I have listed in the link below with our AM62P reference image. Sorry for the inconvenience.
