Today that will be fun, you might be able to modify TI’s latest 9.x sdk and update the git repo to our kernel and u-boot changes… (Ti’s 9.x uses same v6.x kernel and u-boot major version)

Regards,

How different is the BB factory kernel than the j722 ti stuff, I was looking into using that with the .dtb of the beagley.

4

Just swap in our u-boot and device tree and it should boot

5

That is what my thoughts were on that, thank you.
My plans are to install a yocto image with my dev-meta-layer onto NVMe so the remote builds should be smoking fast.

6

You’ll need our pcie clock enable patch, TI is looking for another way to do it

7

Okay, thank you for the heads up on that.

8

Will NVMe run out of the box with the factory image and adapter board?

9

Yeap, and we have setup a user selectable (over serial) boot option, to do that.

10

Network boot too?

1:	microSD (production test)
2:	transfer microSD rootfs to NVMe (advanced)
3:	microSD (debug)
4:	microSD (default)

No onboard storage, so today you need a fat 32 partition on a microSD card… but u-boot dhcp worked last I tried

I was testing this one today… Amazon.com other than getting warm (as another fan somewhere) the poe/NVMe combo works nice

Hi Robert,

I use sdk 9.2 on a sk-am62a-lp with TI yocto edgeai sdk. The idea is to adapt this on the BBY-AI.
If i understand, i just need to use your kernel and your uboot.

The kernel source is here : Robert Nelson / ti-linux-kernel-dev · GitLab

And for u-boot ?

Regards

u-boot here: Files · v2023.04-ti-09.02.00.009-BeagleY-AI-Production · BeagleBoard.org / u-boot · GitLab

Thank you !

About the kernel, can i just keep the ti linux kernel edgeAi and apply your patch ?
Then, Which machine should I declare for yocto build ?
image

17

J722S-evm

@RobertCNelson Are we able to put the C7x DSP AI accelerator on the Beagle board to use? Since the platform uses am67a, do I borrow the TI yocto project for am67a and use your kernel and u boot for the image? Are you able to provide a step-by-step guide in this regard?

Thanks
