Hi,
I'm working with the Odroid XU4 board. I want to execute a standalone application, like the hello_world function that is included with u-boot source. My steps to compile are: 1. clone the u-boot repo 2. `export ARCH=armv7a` 3. `export CROSS_COMPILE=arm-linux-gnueabi-` 4. `make` 5. Use sd_fusing.sh to write the sd card
After boot, I use `setenv loads_echo 1,` and then I am able to use the "loads" command to transfer the file "hello_world.srec," but I am notified:
CACHE: Misaligned operation at range [0c100000, 0c10027a]
and when I try to execute the application via `go 0c100000 hello world,` it hangs and becomes unresponsive. I've tried the other included srec file, but it also fails in the same way. I've tried defining CONFIG_SYS_DCACHE_OFF and the same with ICACHE, as per a blog post, but that was not effective. I've tried abbreviating the file to include only the app_startup() function and a return, but that also doesn't work.
Do you have any advice to help me with this?
Ultimately, I would like to write an application that runs automatically before a kernel image is loaded, in order to take advantage of some system hardware that gets locked when the OS boots. Is this possible?
Best, Michael Neises
