Hi,
I have a nucleo-h743zi, in which I have enabled network.
It seems to work so far.
When I enable Network Info Debug, I get a crash.
The crash does not happen with Network info disabled (Enabling network
warnings and errors is ok)
I am writing on the mailing list to get feedback and discussion.
Here is the crash, pretty obvious cause:
A▒DE
stm32_ethinitialize: intf: 0
stm32_ifdown: Taking the network down
netdev_register: Registered MAC: 2e:7e:27:a2:69:88 as dev: eth0
up_assert: Assertion failed at file:init/nx_start.c line: 703 task: Idle
Task
First of all I dont know where this MAC is obtained but whatever, thats
not my problem. I will put the real mac later.
Note that nx_start is a pretty general file for nuttx, not related to
board or chip.
(gdb) break nx_start.c:703
Breakpoint 1 at 0x8002b9a: file init/nx_start.c, line 703.
Note: automatically using hardware breakpoints for read-only addresses.

=>assert
This function group_setupidlefiles fails to open /dev/console and
triggers an assert.
Now please dont tell me that this code will work when I remove debug, I
dont care. This is not the root cause.
Does this code fails to open the console because some network debug has
been emitted first?
What to do, then?
It is pretty common to have boards emit debug messages before the OS is
started. I cant believe I'm the only one that will see this.
It seems to happen before I have CONFIG_DEV_CONSOLE, which is the
default, and is ok, since i'm just using a serial port with this board.
If I disable CONFIG_DEV_CONSOLE, then nsh does not start, so I believe
this setting is required.
USB console is not enabled nor planned to be used.
Can you please help me understand and fix this?
It does not look to be recent code.
Thanks,
Sebastien
