The standard load address for the kernel is at 0x11000000 and the load address for the device tree is at 0x12000000. This has space for a kernel of up to 16 MB. If your kernel image is bigger, but you still load the device tree to 0x12000000, then the…

Hello,

I have built an Kernel image with a bundled initramfs, to show a bootscreen very early using Plymouth. The Kernel image is about 20 MB in size. The default partition size for the Kernel (address $Kernel in U-Boot) is 7 MB in size.

I have…

Yes.that's true. The penguins appear immediatley when the display driver is activated. fbsplash and plymouth cannot appear before the root filesystem is mounted, because they are taken from there. One solution may be a modification…

Hi,

thank you for the detailed answer. I now see the problem is of bigger concern.

However, I could successfully build an initramfs, bundled with the Kernel in a single image. I use this recipe in my custom layer, and I use Plymouth for bootscreen.

Hello again,

we are currently in the process of evaluating possible ethernet solutions.
Particularly a small ethernet switch and an external phy.

As both of these parts have to be on the carrier board of the PicoCore, we would have to route the…

If you use an external 3.3V supply, you have to make sure, that the voltage is not applied to the PicoCore pins during reset.
If voltage to the PicoCore pins is applied, then the processor is powered through this voltage.

You have to decouple the…

Hello,

we conducted additional tests today on the F&S starter kit, a PicoCore with default image from the SD card directory of the Buildroot release (Linux fsimx8mm 5.15.131-F+S #2 SMP PREEMPT Fri Nov 10 18:39:16 CET 2023 aarch64 GNU/Linux), nothing…

Hello,

thanks, just a quick reply.

I quickly setup another PicocoreMX8MM starter kit (PCoreBBDSI Rev1.40), same PicoCore, run the iperf3 test with the same results. Eth0 is down after 60 seconds. A reset gets the interface back online. The starter…
