Having an incorrect value for the name/location of the kernel file.Īt the point the screen shoes the Hit any key to stop autoboot - hit any key and you can break into the u-boot console.Confused the hell out of me when I had that issue, and spent days trying to debug a non-existant problem! If it is wrong, your board may actually be booting, you just can't see it as the messages are being sent to a port you are not looking at.
#Imagetype ap iptc serial
This should be the name of your serial port, e.g. Not passing in the correct value for console=. That shows that u-boot is trying to boot :) It immediately seemed to boot my kernel instead. Recipes-bsp/u-boot/files/fw_env.config:1:/boot/uboot.env 0x0000 0x4000īut I don't know what to make out of this for the moment.Īssuming there is no uboot at all on my system so far: What layer/recipe should I get to have uboot?Īssuming there somehow already is a uboot in my image: How can I access uboot? I tried to ctrl+c during the rpi's startup but I didn't get uboot's command line.

I am using a raspberry pi 3 model b+ and building a core-image-minimal using this layer from openembedded. 
I don't think this is what I actually need. But I only found some scripts and devtools. I want to add uboot to my yocto image in order to later configure it. I tried looking online but was quite confused on how I should approach this.
