|
Hi all -
I have an espresso bin and I was following this page:
https://wiki.gentoo.org/wiki/ESPRESSOBin
I grabbed the code from here https://github.com/sarnold/arm64-multiplatform
and used the build script with no issues. I wanted to try booting the kernel after loading it over tftp. So, I got to the uboot prompt and did the following:
| Code: |
TFTP from server 10.10.0.1; our IP address is 10.10.0.2
Filename '/boot/4.13.12-aarch64-r0.Image'.
Load address: 0x200000
Loading: #################################################################

and it just sits. That is okay. I got it to load something into memory - baby steps. But I am wondering what I am missing? Is there a specific address I need to load the code into? Is it even supposed to do anything at that point? I was expecting to see "something" (messages, etc.) and then a kernel panic because it is missing everything else. Could someone point me in the right direction?
Thanks! |

Got it!
I kept reading the page and realized I needed to:
setenv bootargs $console
where
console=console=ttyMV0,115200 earlycon=ar3700_uart,0xd0012000
and then run booti
Messages and a kernel panic! |
