- Hi Tim, still working on releasing the 10 SDK but I did push the mitysom-auto-flash-emmc image to the kirkstone meta-mitysom repo.

- Hi,

-- Yes, need help for the same.
I didnt get the below modifications described in the previous reply. Do i need to modify kernel like this?

How are you loading the processor with the ARM RTOS and DSP RTOS? What boot media are you using, you said you aren't using sdcard? In my experience, we would boot into u-boot and then use u-boot to load the FPGA, DSP and AR... - AK 06:56 AM MitySOM-AM57X Software Development: RE: Hello World on DSP

- Just to follow up, you'll need to make sure the path to the eeprom file is correct in the code.

- If you don't want to use debugfs, you can try to read it from the sysfs eeprom file.
We have utility code as part of other MitySOM uBoot repositories that can be compiled to do this at the link below.

- Hello,
For the bootmode pins:
1. If you are concerned about isolation, you can use a tristate buffer to drive/tristate the bootmode pins using the PORz_OUT signal from the SOM. See the schematic below as an example we used for ano... - JC 08:54 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P PCB Development: RE: Isolation resistors for Bootmode pins on the AM62A Mity-SoM?

I plan to use those video out signals to drive a parallel RGB 24-bit display instead of an HDMI chip. I am considering adding the isolation resistors but make them 0-ohm initially, just to be safe. This way they can b... - JC 07:48 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P PCB Development: RE: Isolation resistors for Bootmode pins on the AM62A Mity-SoM?

I'm new to this forum, sorry about that. - Hi,
On the TI's Eval board for the AM62A (AM62A-SKEVM) they include isolation resistors between Bootmode signals and the SoC pin as shown:

- Thanks Jonathan and Joshua for the info.
We will wait for you to release the updates for version 10 of the SDK, then merge it with our yocto layer.
We are interested in taking Jonathan up on the offer to "provide a flash.sh script ... - BD 03:11 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P Software Development: RE: PRU RP Msg Driver Functionality

(I see that your use of the 57x documentation was not really a mistake. I didn't know you were testing with that platform.) - BD 03:08 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P Software Development: RE: PRU RP Msg Driver Functionality

- Thanks Joshua,
We are currently on a 57x. It seems version 10 of that sdk will not drop until next year. My plan is to go back to 8. The PRUs still worked there and some c++ features my team wants are supported there. - JB 02:21 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P Software Development: RE: PRU RP Msg Driver Functionality
- Perfect, just a heads up that we are currently testing to release the 10 sdk, which TI highly recommends using. It may be better to wait and move to that instead of the 9.
Best,

- Hi Nathan,
You are asking about PRU support for the AM62x platforms, correct? (I am asking because we also have AM57x platforms, and your thread is referring to AM57x support).
Thanks,
