Hello, friends!
I'm interested if there is any internal Barebox convention about
return types and values of initcall functions. What shall return
my initcall if I want to stop booting and display error message?

Well, how can I call C functions from shell without implementing own shell

My board contains mcp79411 - it's an I2C RTC with EEPROM, which contains
global-registered MAC address. I want this MAC address to be read by Barebox
and passed to Linux kernel FEC driver through bootargs. I was trying to find

You can't get the output of a command, that's not implemented. Some

Got that. However this option seems to be not so universal as if env
is linked straight to binary image.

Dear friends,
Still cannot make my environment be compiled into barebox final image.
Maybe I missed something? Which config parameters should be set
to do this?..

Hi friends,
I need some help with barebox environment management. I've added env/config file
to arch/arm/myboard/ directory, fixed Makefile with `bbenv-y += env` string, but
this config file doesn't apply on barebox boots. What can be the reason for
such a problem?

Dear friends,
I faced a strange problem with serial ports on my board. I have 4 imx-uart's

- CONFIG_CONSOLE_ACTIVATE_FIRST is set Y,
- CONFIG_CONSOLE_ACTIVATE_ALL is set N

Enabel initcall debug - then you can see when they are called.
It is a very usefull debug tool.
Use the .map

There is no such reference, but look at what other DT enabled

Looking at the history I could see that dlmalloc was present since barebox
was forked from U-boot. So and old
Is there any another way to link DT to the image besides

A new portion of questions is ready:)
1. dlmalloc or tlsf - what are pros and cons of each of them?
2. Does barebox apply IMX's pinctrl settings if they are present in DT? If yes,
why do we need setup_uart() function in pbl code?

Hi, I'm trying to add my own custom board support to barebox. It's based on
i.MX6ULL CPU.
So, I have the following questions:
